Radar images show large swath of West Texas oil patch is heaving and sinking at alarming rates

Analysis indicates decades of oil production activity have destabilized localities in an area of about 4,000 square miles populated by small towns, roadways and a vast network of oil and gas pipelines and storage tanks

Two giant sinkholes near Wink, Texas, may just be the tip of the iceberg, according to a new study that found alarming rates of new ground movement extending far beyond the infamous sinkholes.

That’s the finding of a geophysical team from Southern Methodist University, Dallas that previously reported the rapid rate at which the sinkholes are expanding and new ones forming.

Now the team has discovered that various locations in large portions of four Texas counties are also sinking and uplifting.

Radar satellite images show significant movement of the ground across localities in a 4000-square-mile area — in one place as much as 40 inches over the past two-and-a-half years, say the geophysicists.

“The ground movement we’re seeing is not normal. The ground doesn’t typically do this without some cause,” said geophysicist Zhong Lu, a professor in the Roy M. Huffington Department of Earth Sciences at SMU and a global expert in satellite radar imagery analysis.

“These hazards represent a danger to residents, roads, railroads, levees, dams, and oil and gas pipelines, as well as potential pollution of ground water,” Lu said. “Proactive, continuous detailed monitoring from space is critical to secure the safety of people and property.”

The scientists made the discovery with analysis of medium-resolution (15 feet to 65 feet) radar imagery taken between November 2014 and April 2017. The images cover portions of four oil-patch counties where there’s heavy production of hydrocarbons from the oil-rich West Texas Permian Basin.

The imagery, coupled with oil-well production data from the Railroad Commission of Texas, suggests the area’s unstable ground is associated with decades of oil activity and its effect on rocks below the surface of the earth.

The SMU researchers caution that ground movement may extend beyond what radar observed in the four-county area. The entire region is highly vulnerable to human activity due to its geology — water-soluble salt and limestone formations, and shale formations.

“Our analysis looked at just this 4000-square-mile area,” said study co-author and research scientist Jin-Woo Kim, a research scientist in the SMU Department of Earth Sciences.

“We’re fairly certain that when we look further, and we are, that we’ll find there’s ground movement even beyond that,” Kim said. “This region of Texas has been punctured like a pin cushion with oil wells and injection wells since the 1940s and our findings associate that activity with ground movement.”

Lu, Shuler-Foscue Chair at SMU, and Kim reported their findings in the Nature publication Scientific Reports, in the article “Association between localized geohazards in West Texas and human activities, recognized by Sentinel-1A/B satellite radar imagery.”

The researchers analyzed satellite radar images that were made public by the European Space Agency, and supplemented that with oil activity data from the Railroad Commission of Texas.

The study is among the first of its kind to identify small-scale deformation signals over a vast region by drawing from big data sets spanning a number of years and then adding supplementary information.

The research is supported by the NASA Earth Surface and Interior Program, and the Shuler-Foscue Endowment at SMU.

Imagery captures changes that might otherwise go undetected
The SMU geophysicists focused their analysis on small, localized, rapidly developing hazardous ground movements in portions of Winkler, Ward, Reeves and Pecos counties, an area nearly the size of Connecticut. The study area includes the towns of Pecos, Monahans, Fort Stockton, Imperial, Wink and Kermit.

The images from the European Space Agency are the result of satellite radar interferometry from recently launched open-source orbiting satellites that make radar images freely available to the public.

With interferometric synthetic aperture radar, or InSAR for short, the satellites allow scientists to detect changes that aren’t visible to the naked eye and that might otherwise go undetected.

The satellite technology can capture ground deformation with an accuracy of sub-inches or better, at a spatial resolution of a few yards or better over thousands of miles, say the researchers.

Ground movement associated with oil activity
The SMU researchers found a significant relationship between ground movement and oil activities that include pressurized fluid injection into the region’s geologically unstable rock formations.

Fluid injection includes waste saltwater injection into nearby wells, and carbon dioxide flooding of depleting reservoirs to stimulate oil recovery.

Injected fluids increase the pore pressure in the rocks, and the release of the stress is followed by ground uplift. The researchers found that ground movement coincided with nearby sequences of wastewater injection rates and volume and CO2 injection in nearby wells.

Also related to the ground’s sinking and upheaval are dissolving salt formations due to freshwater leaking into abandoned underground oil facilities, as well as the extraction of oil.

Sinking and uplift detected from Wink to Fort Stockton
As might be expected, the most significant subsidence is about a half-mile east of the huge Wink No. 2 sinkhole, where there are two subsidence bowls, one of which has sunk more than 15.5 inches a year. The rapid sinking is most likely caused by water leaking through abandoned wells into the Salado formation and dissolving salt layers, threatening possible ground collapse.

At two wastewater injection wells 9.3 miles west of Wink and Kermit, the radar detected upheaval of about 2.1 inches that coincided with increases in injection volume. The injection wells extend about 4,921 feet to 5,577 feet deep into a sandstone formation.

In the vicinity of 11 CO2 injection wells nearly seven miles southwest of Monahans, the radar analysis detected surface uplift of more than 1 inch. The wells are about 2,460 feet to 2,657 feet deep. As with wastewater injection, CO2 injection increased pore pressure in the rocks, so when stress was relieved it was followed by uplift of about 1 inch at the surface.

The researchers also looked at an area 4.3 miles southwest of Imperial, where significant subsidence from fresh water flowing through cracked well casings, corroded steel pipes and unplugged abandoned wells has been widely reported.

Water there has leaked into the easily dissolved Salado formation, created voids, and caused the ground to sink and water to rise from the subsurface, including creating Boehmer Lake, which didn’t exist before 2003.

Radar analysis by the SMU team detected rapid subsidence ranging from three-fourths of an inch to nearly 4 inches around active wells, abandoned wells and orphaned wells.

“Movements around the roads and oil facilities to the southwest of Imperial, Texas, should be thoroughly monitored to mitigate potential catastrophes,” the researchers write in the study.

About 5.5 miles south of Pecos, their radar analysis detected more than 1 inch of subsidence near new wells drilled via hydraulic fracturing and in production since early 2015. There have also been six small earthquakes recorded there in recent years, suggesting the deformation of the ground generated accumulated stress and caused existing faults to slip.

“We have seen a surge of seismic activity around Pecos in the last five to six years. Before 2012, earthquakes had not been recorded there. At the same time, our results clearly indicate that ground deformation near Pecos is occurring,” Kim said. “Although earthquakes and surface subsidence could be coincidence, we cannot exclude the possibility that these earthquakes were induced by hydrocarbon production activities.”

Scientists: Boost the network of seismic stations to better detect activity
Kim stated the need for improved earthquake location and detection threshold through an expanded network of seismic stations, along with continuous surface monitoring with the demonstrated radar remote sensing methods.

“This is necessary to learn the cause of recent increased seismic activity,” Kim said. “Our efforts to continuously monitor West Texas with this advanced satellite technique can help sustain safe, ongoing oil production.”

Near real-time monitoring of ground deformation possible in a few years
The satellite radar datasets allowed the SMU geophysicists to detect both two-dimension east-west deformation of the ground, as well as vertical deformation.

Lu, a leading scientist in InSAR applications, is a member of the Science Team for the dedicated U.S. and Indian NASA-ISRO (called NISAR) InSAR mission, set for launch in 2021 to study hazards and global environmental change.

InSAR accesses a series of images captured by a read-out radar instrument mounted on the orbiting satellite Sentinel-1A/B. The satellites orbit 435 miles above the Earth’s surface. Sentinel-1A was launched in 2014 and Sentinel-1B in 2016 as part of the European Union’s Copernicus program.

The Sentinel-1A/B constellation bounces a radar signal off the earth, then records the signal as it bounces back, delivering measurements. The measurements allow geophysicists to determine the distance from the satellite to the ground, revealing how features on the Earth’s surface change over time.

“Near real-time monitoring of ground deformation at high spatial and temporal resolutions is possible in a few years, using multiple satellites such as Sentinel-1A/B, NISAR and others,” said Lu. “This will revolutionize our capability to characterize human-induced and natural hazards, and reduce their damage to humanity, infrastructure and the energy industry.” — Margaret Allen, SMU

SMU student to share innovative texting app at SXSW Red Bull Launch Institute

Users earn rewards with the “Just Drive” app designed to prevent distracted driving.

Neha Husein gripped her steering wheel as her car jolted forward, hit from behind on one of Dallas’ busiest and most dangerous freeways. Shaken, but not injured, the high school senior surveyed the significant damage to her car. The cause of the crash? The driver behind her was texting while driving.

The 2014 collision was the SMU junior’s inspiration to develop a solution to stop drivers from texting while driving, a practice that killed 455 Texans and played a role in 109,660 crashes in Texas in 2016. Her smart-phone app, “Just Drive,” awards points to drivers who lock their phones while driving. Those points can then be redeemed for coupons or free food, drinks or merchandise.

Husein is one of six college entrepreneurs selected to participate March 10 in the Red Bull Launch Institute at Austin’s South by Southwest Interactive Festival. She will meet with industry leaders and other entrepreneurs to further develop and amplify her project. The institute is scheduled from 3 to 6:30 p.m. at Palazzo Lavaca, 1614 Lavaca St., Austin.

She’s not being judgmental. Everyone has texted while driving, Husein says.

“We are used to multitasking, and sitting in traffic gets boring,” she says.

But the marketing and human rights major believes positive reinforcement can change behavior. Rewards are motivating to millennials like Husein. According to the Texas Department of Transportation, drivers age 16 to 34 are most likely to text while driving, but Husein is betting the app will appeal to all ages.

“Expecting incentives is a generational thing, but it’s a human thing too,” she says. “People enjoy rewards.”

Husein first presented “Just Drive” at SMU’s October 2017 Big Ideas pitch contest. She won $1,000 for her 90-second pitch and used it to create a wireframe app mock-up. The Big Ideas pitch contest is part of SMU’s Engaged Learning program, a campus wide initiative designed to enhance student learning by connecting a personal passion to academic learning and turning it into a personal project. Faculty mentorship is a key part of the Engaged Learning program.

Husein’s mentor, SMU law professor Keith Robinson, is a specialist in patent, intellectual property and technology law and co-directs the Tsai Center for Law, Science and Innovation in SMU’s Dedman School of Law. He also teaches a class to law students on designing legal apps.

“I like people who show initiative and are willing to bet on themselves,” says Robinson, who meets weekly with Husein to discuss intellectual property issues and trademark application. “Neha has developed an app for a relatable problem, one that can save lives.”

Husein is a Carrollton, Texas, native who grew up with an entrepreneur mindset. She remembers manning a toy cash register alongside her father at his convenience store. He was on hand in February 2018 to see his daughter present her business plan at the second stage of SMU’s Big Ideas competition – and win $5,000 in start-up funds.

“Just Drive is a perfect combination of my interests in human rights and marketing,” Husein says. “It combines business with a philanthropic cause.”

She plans to launch the “Just Drive” app in September, 2018. — Nancy George, SMU

KERA: 8 Questions For The Government To Consider Before Investigating Encrypted Data

“This debate is quite polarizing; it’s been in the media for a couple of years now. It was quite an accomplishment on our part to agree on a set of facts, to agree on a vocabulary and to agree on the framework.” — Fred Chang, SMU

Journalist Justin Martin with KERA public radio covered the new government guidelines for investigating encrypted data from the National Academies of Sciences, Engineering and Medicine. Frederick Chang, director of SMU’s Darwin Deason Institute for Cyber Security and former director of research for the National Security Agency, participated in developing the guidelines.

KERA’s interview, “8 Questions For The Government To Consider Before Investigating Encrypted Data,” aired March 7, 2018.

Chang, a member of the prestigious National Academy of Engineering, joined SMU in September 2013 as Bobby B. Lyle Endowed Centennial Distinguished Chair in Cyber Security, computer science and engineering professor and Senior Fellow in the John Goodwin Tower Center for Political Studies in Dedman College. The Darwin Deason Institute for Cyber Security was launched in SMU’s Lyle School of Engineering in January 2014, with Chang named as its director.

In addition to his positions at SMU, Chang is a distinguished scholar in the Robert S. Strauss Center for International Security and Law at the University of Texas at Austin. Chang has been professor and AT&T Distinguished Chair in Infrastructure Assurance and Security at the University of Texas at San Antonio and he was at the University of Texas at Austin as an associate dean in the College of Natural Sciences and director of the Center for Information Assurance and Security. Additionally, Chang’s career spans service in the private sector and in government including as the former Director of Research at the National Security Agency.

Chang has been awarded the National Security Agency Director’s Distinguished Service Medal and was the 2014 Information Security Magazine ‘Security 7’ award winner for Education. He has served as a member of the Commission on Cyber Security for the 44th Presidency and as a member of the Computer Science and Telecommunications Board of the National Academies. He has also served as a member of the National Academies Committee on Responding to Section 5(d) of Presidential Policy Directive 28: The Feasibility of Software to Provide Alternatives to Bulk Signals Intelligence Collection.

He is the lead inventor on two U.S. patents, and he appeared in the televised National Geographic documentary, Inside the NSA: America’s Cyber Secrets. He has twice served as a cyber security expert witness at hearings convened by the U.S. House of Representatives Committee on Science, Space and Technology.

Chang received his B.A. degree from the University of California, San Diego and his M.A. and Ph.D. degrees from the University of Oregon. He has also completed the Program for Senior Executives at the Sloan School of Management at the Massachusetts Institute of Technology.

Listen to the KERA radio interview with Justin Martin.

EXCERPT From KERA News:

The debate over government access to personal and private information dates back decades. But it took center stage after the 2015 mass shooting in San Bernardino, California, when Apple refused to open a backdoor into an assailant’s encrypted cell phone for FBI investigators.

The agency ultimately paid a hacker to unlock the phone instead.

Now, the National Academies of Sciences, Engineering, and Medicine has produced a set of guidelines for government agencies to consider before approaching or investigating encrypted data.

To learn more about them, I talked with Frederick Chang, the executive director of Southern Methodist University’s Darwin Deason Institute for Cyber Security.

He’s also a member of the National Academy of Engineering and former director of research for the National Security Agency.

Cyber grad and U.S. Marine Corps vet Michael Taylor proved his mettle as an outstanding student researcher

‘Outstanding student in computer science & engineering’ graduates Dec. 16 with master’s degree and Raytheon ticket to a Ph.D.

Michael Taylor will be the first to tell you that he was not ready for college when he graduated from Plano East High School in 2006. And he’ll also tell you that nobody was more surprised than he was when SMU admitted him in 2014, a little later than the average undergrad.

But Taylor’s disciplined approach to life, honed through five years in the Marine Corps, combined with the intelligence he learned to tap, has earned him a master’s degree from SMU’s Lyle School of Engineering that will be awarded Dec. 16. And after proving his mettle as a student researcher in Lyle’s Darwin Deason Institute for Cyber Security, Taylor has been awarded the first Raytheon IIS Cyber Elite Graduate Fellowship, which will fund his Ph.D. in quantum computing at SMU and then put him to work as an employee at Raytheon.

“Michael Taylor stood out to me when I first had him in an undergraduate class,” said Mitch Thornton, research director for the Deason Institute and Cecil H. Green Chair of Engineering at SMU. “I could sense there was something special about him and that he had a lot of talent. I actively encouraged Michael to do research with me and he has excelled in everything I have asked him to work on. He is a credit to the student body of SMU’s Lyle School, and a credit to the nation.”

Taylor learned to focus on the details in the Marine Corps. He had sampled community college very briefly after high school, but it didn’t stick. He knew he didn’t have skills to trade for a decent job, so joining the Marine Corps made sense to him.

“Honestly? In retrospect, I wasn’t ready for school,” Taylor acknowledged.

After the Marines, finally ready for college
Taylor’s dad was an SMU engineering alumnus, and this was not the career path he’d envisioned for his son. But it’s funny how things work themselves out. Taylor completed Marine basic training, and took an aptitude test to determine where his skills might fit the Marine Corp mission. He did very, very well.

“My score on that test – I qualified for every enlisted job in the Marine Corps,” Taylor said. “I got to pick what job I wanted.” Working as a calibration technician sounded interesting – a job that would require him to conduct testing for proper operation of a wide range of mechanical and electronic devices and tools. But before working in calibration, he’d have to go school for a year.

“Ironic, I know,” Taylor said, smiling. “I had to sign up for an extra year, so I ended up doing a five-year tour in the Marines.”

He spent most of that time working out of Camp Pendleton in California, but was deployed to Helmand Province, Afghanistan, from March through September 2010, at the height of the surge of U.S. troops. “I wasn’t a combat guy,” Taylor said. “But even on base, sometimes, the rockets would come in the middle of the night.”

Nearing the end of his enlistment in 2012, Taylor was getting the hard sell to stay in and make the Marines a career. By now, he had decided he was ready for college, but the career planner he met with tried hard to talk him out of it, predicting that Taylor would “fail again.”

“He actually told me if I got out of the Marine Corps and went back to college, I’d end up living under a bridge,” Taylor said, shaking his head. It just made him more determined to succeed.

He started back at community college, and this experience was very different. “It seemed like it was so hard the first time,” Taylor said. “What then seemed like a monumental task, now seemed like nothing. I started thinking, I might be able to do school, now.”

And he started thinking about SMU. Taylor’s grades at Collin County Community College were good – good enough to get him into his father’s alma mater.

SMU Prof’s mentoring made all the difference
Taylor never dared to think he could live up to what his Dad had accomplished, starting with the scholarship to attend SMU that Jim Taylor ’89 had received from Texas Instruments. “He was a technician there,” Taylor recalled, “and they paid for him to come here. As a kid, if you’d told me I could do something like that, too, I’d never have believed you. For me there was Albert Einstein, and Jim Taylor.”

Michael Taylor came to the Hilltop on the GI Bill, and SMU’s Yellow Ribbon program for military veterans covered what the GI Bill didn’t. Then, the Darwin Deason Institute for Cyber Security picked up the cost of his master’s degree.

Taylor’s first semester at SMU’s Lyle School was a tough adjustment after his relatively easy path at community college, but that class with professor Thornton his second semester changed everything. “Dr. Thornton offered me a position working in the Deason Institute for Cyber Security,” Taylor said. “It’s been going great since then.”

Thornton’s influence and mentoring made all the difference for Taylor.

“If I had not met Dr. Thornton, there were times I wondered if I would have gotten my bachelor’s degree. I definitely wouldn’t be getting the master’s degree. And a Ph.D. wouldn’t have been something I ever considered.”

Compelled to dive into quantum computing and cyber security
Taylor was interested in computer hardware when he arrived at SMU, but the Deason Institute opened the door to the contributions he could make in cyber security. He received the Lyle School’s 2017 Rick A. Barrett Memorial Award for outstanding work in computer science and engineering. And as he neared the completion of his master’s degree, he was tapped for the Raytheon Cyber Elite Graduate Fellowship and is looking forward to pursuing his Ph.D. in quantum computing.

“Quantum computers solve problems that are too difficult for classical computers to solve,” Taylor said. “Certain problems in classical computation are intractable, there’s no way you can solve them in this lifetime. It’s only a matter of time before quantum computers render all encryption obsolete.”

For Fred Chang, executive director of SMU’s Deason Institute and former research director for the National Security Agency (NSA), finding talented students like Taylor to fill the gaps in the cyber security workforce is “job one.” Chang testified before a congressional subcommittee in September that we are likely facing a worldwide shortage of cyber security workers five years from now.

“Today’s students will be responsible for designing, creating, operating, maintaining and defending tomorrow’s cyber infrastructure,” Chang explained. “We need a large and capable pool of folks to staff these positions for the future.”

For Taylor, cyber security is just plain compelling.

“I just like the challenge. There’s somebody out there that’s trying to crack what you have, to break you down. You have to be smarter than them. It’s a game!” — Kim Cobb, SMU
