Cathy,
The Gas Well Inspections Division is working with the TCEQ to obtain a copy of their air sampling results. The TCEQ estimated four weeks before they will receive the results. In addition, TCEQ stated a concluding report will likely be released towards the end of June. Each of these items will be requested by the City. If you feel any of TCEQ’s information will be helpful to you, please feel free to also request the information from TCEQ. The main line for the Region 4 TCEQ office is 817-588-5800.
As I mentioned to you in a previous email, this site was approved (GWP03-0006) on April 18, 2003. In addition, the City issued Fire Permit number 03-083 for the Bradford 1 well. The Smith-Yorlum 7H gas well was originally permitted by the RRC as the Bradford 1 vertical well, but in 2012, EagleRidge Operating, LLC obtained a new RRC permit to recomplete the well with a horizontal profile and change the well name. A City permit is not required to recomplete, re-drill, or deepen an existing well; therefore, we do not have records in addition to Fire Permit number 03-083. Permitting information is available online via our TRAKiT software by utilizing the Public Login, https://www1.cityofdenton.com/eTrakIt2/Login.aspx?type=public. The issued Fire Permit, 03-083, is not included in this system due to the age of the permit. The Gas Well Inspections Division, however, created a tracking permit to log records and inspections in TRAKiT under number 1108-0323. The City’s mapping program contains some gas well data, http://maps.cityofdenton.com/mapviewer/index_flex.aspx. We track drilling and production site details (e.g., site dimensions and boundaries, layout, approval dates, etc.), and log inspection results and specific information for each well and gas well permit (e.g., well name, surface hole location, operator, inspections, permitting dates, etc.) The data management associated with these details is compiled in a spreadsheet and available through TRAKiT, but will be transferred to the mapping program once our department GIS Intern positions are staffed.
As for the frac plugs, the well operator of record is EagleRidge. All work performed on the site should be the responsibility of the operator. Manufacturer information is not reviewed by the City.
EagleRidge is anticipated to submit a summary report in approximately 2-4 weeks. The summary report may include your requested details regarding depth of drilling and where control of the well was lost. According to preliminary reports, however, it appears EagleRidge concluded drilling and hydraulic fracturing of the well and was performing completion activities.
EagleRidge safety records and training are not reviewed by the City. Preliminary research of EagleRidge wells indicated that approximately 10 other wells in the City of Denton were deepened from vertical profile to horizontal profile by EagleRidge.
