The California Sate oil and gas regulatory agency the Division of Oil, Gas and Geothermal Resources (DOGGR) an agency of the Department of Conservation has permanently closed 33 injection wells in the State. Including one well in Ventura County located in the Sespe Field.
This is part of the overall of the Underground Injection Control (UIC) program which came under fired over the past year as being inadequate according to federal standards. Injection wells are used for disposal and/or to enhance production from nearby standard production wells.
The injection well in Ventura County now permanently closed is API number 11102615. It is operated by Seneca Resources and is located in the Tar Creek/Topa Topa Area. The well was first drilled in 1963 then converted to a water disposal well in 1988.
The zone of injection was previously thought to hold water with a Total Dissolved Solid count of 4600. This was over the 3000 threshold. But a recent recheck reveal the formation in fact had a TDS count of 900. This means that formation is protected under the federal Safe Drinking Water Act and the injection well is in violation.
The record also contains a notice from DOGGR in Dec. 2011 notifying Seneca the well is noted as Active in the records, but the company has failed to report the injection pressures as required. Then before that in July of 2010, DOGGR had sent another document to Seneca notifying them the mechanical integrity test (MIT) survey as required was "overdue." The record does contain emails from an engineer with Seneca dated May 2009, where he states tests are being scheduled and he confirms which tests are required. He notes that this well requires a "water injection survey."
The record shows in 1991 there were issues with the hydrostatic pressure and the well was to be shut in by Jan. 1 1992. Other information in the well involves fresh water in the area.
