Smith, Vice President apsmith@gsi-net.com; 512.346.4474 Submission Date 31 July 2018 DUNS Number 181780776 Recipient Organization GSI Environmental Inc. 9600 Great Hills Trail, Suite 350E Austin, Texas 78759 Project Period October 1, 2016 to May 31, 2019 Reporting Period End Date June 30, 2018 Report Term or Frequency Quarterly Signature of Submitting Official 2. ACCOMPLISHMENTS: Mandatory a) What are the major goals of the project? The primary goal of the project is to employ a novel combination of complementary measurement methods and technologies to detect and accurately quantify average annual methane emissions from underground natural gas storage facilities, including from above-ground equipment leaks plus seepage at the ground surface from underground leaks. b) What was accomplished under these goals? All project goals for the third quarter (Q3) reporting period of April – June 2018 were met. A summary of the activities performed to achieve project goals during Q3 is included below. High Resolution Subsurface Leak Monitoring Soil Heat Data Analysis: Upon initial review of soil temperature profile data from both wells at Clay Basin, the team observed much higher than expected interference from diurnal temperature variations at the well heads, extending to all monitored depths. Review of current literature and technical publications confirmed that the issue has not been studied previously.
