OGS hosts technical and core workshop on the STACK Play

Last September, the Oklahoma Geological Survey hosted a workshop focusing on the Sooner Trend Anadarko Basin Canadian and Kingfisher Counties (STACK) Play in Oklahoma. The play was discovered in 2011, and has quickly become one of the hottest resource plays in North America. Despite extensive drilling activity in this play, understanding of the petroleum geology of the area is limited.

The workshop spanned two days, beginning with a day-long technical workshop held at the Moore-Norman Technology Center, which was attended by over 200 people. The following day, two half-day workshops focusing on core were held at the OGS’s Oklahoma Petroleum Information Center (OPIC) in Norman. Each core workshop was attended by around 40 people.

The main objective of the technical workshop was to learn from researchers and operators in the STACK Play, with an emphasis on the Meramec Lime and Woodford Shale. The core workshops presented core from several key wells of the Meramec and Woodford Shale in Blaine, Kingfisher, and Canadian Counties.

David Brown, OGS Associate Director, said that the OGS was uniquely suited for hosting this workshop.

“It’s one of the most important plays in the country right now,” Brown said, “and it happens to be in our backyard.”

OGS Hosts Seismology Workshop for Teachers

Eleven educators participated in a two-day workshop hosted by the Oklahoma Geological Survey. The educators are part of a project called BLOSSM in Oklahoma. BLOSSM (Bridging Local Outreach & Seismic Signal Monitoring) aims to place a total of 100 personal seismographs (Raspberry Shakes) into educational institutions in Oklahoma, including schools, libraries, and museums. During the first day of the two-day workshop, teachers and librarians received a Raspberry Shake, learned how to install it in their educational facility, and experimented with the type of data it collects. During the second day of the workshop, participants explored introductory seismology and Earth science concepts with the help of State Seismologist, Dr. Jake Walter, his undergraduate student, Sarah Sundberg, and Education & Outreach Coordinator, Dr. Molly Yunker. Participants concluded the workshop with numerous resources including lesson plans, ideas for classroom activities, a working seismograph, seismology posters, and other teaching tools to aid in STEM education next fall and beyond.

USGS Forecast for Damage from natural and Induced Seismicity for 2018

The U.S. Geological Survey has released updated maps identifying potential ground-shaking hazards.  The report shows continuing elevated risk of damage in Oklahoma, with some expansion of the area of greatest concern.  The expanded area is in part due to slight increases in seismicity in areas that have experienced very few earthquakes previously.  The results are significantly dependent upon algorithms used to distinguish main events from aftershocks, which may be different for induced than for natural earthquakes.  Earthquake frequency has declined by more than three quarters from the peak in 2015-2016.  The Oklahoma Geological Survey, the Oklahoma Corporation Commission, industry and university scientists, are collaborating together to further reduce seismic activity in Oklahoma.

Oklahoma researchers’ studies on Pawnee quake focus of peer-reviewed journal

Seismological Research Letters, an internationally recognized peer-reviewed journal, is dedicating a special issue to scientific studies related to the 5.8 magnitude earthquake that struck near Pawnee last September — the largest recorded seismic event in Oklahoma history.
