Terra-Petra, environmental engineering construction division was recently contacted to prepare an Oil Well History Report of 20 oil wells located within an 18 acre site in Huntington Beach, California. In accordance with the requirements of the Huntington Beach Fire Department, Terra-Petra’s team provided the “sniff test” on the oil well heads to check for leaks and then follow-up appropriately with actions to stop any leakage found.

The scope of work began with surveying and staking the location of all 20 oil wells, providing excavation equipment and labor to uncover 15 of the abandoned wells, while making them safe for entry. Dave Lucero, Terra-Petra’s Senior Project Scientist, was responsible for managing all excavations (as well as backfilling) and overseeing all field activities. Dave also monitored all soil stockpiles for V.O.C. emissions and dust control per the requirements of the South Coast Air Quality Management District’s Rule 1166.1. With Dave’s extensive field experience and expert project oversight all oil wells were located, excavated, and exposed for “sniff” testing.

Larry Barnes, Terra-Petra’s Senior Geologist, took charge of conducting the “sniff” testing of the 15 excavated oil wells, 5 vented oil wells and monitoring for fugitive gas emissions at each well head per the requirements of Huntington Beach Fire Department City Spec. 422 and the California Division of Oil, Gas, and Geothermal Resources. As a California Licensed Petroleum Geologist, Larry’s duties include documenting the wells’ history, the casing and liners of the wells, well diagrams, the type of cement used to complete the well abandonments, as well as information on all oil/gas zones. With this information Larry is able to provide the developer with an ongoing Oil Well History Report for the Huntington Beach site. His expert knowledge in the geological field and long-standing relationship with DOGGR facilitate the process of determining the level of safety for structures to be built over or near the wells and the corresponding safety recommendations. With this joint expertise within the construction team, Terra-Petra was able to meet the client’s expedited schedule. Thus far, no leakage has been detected on the site, and the client is now prepared to do with the necessary gas mitigation measures for the safety of future site residents.
