Terra-Petra Completed Successful Oil Well Leak Test

Terra-Petra Completed Successful Oil Well Leak Test

Terra-Petra completed another successful oil well leak test, this time in Placentia, CA.

We were on-site to direct the excavation contractor in an effort to locate two buried oil wells on a property scheduled for a commercial redevelopment.

Once uncovered, Terra-Petra completed in oil well leak testing activities accordance with State of California Department of Conservation, Geologic Energy Management Division (CalGEM) guidelines and the Placentia Fire & Life Safety’s Combustible Soil Gas Hazard Mitigation Guideline. The top of thw well casings were located at 11.5’ below surface grade.

Results of the emissions monitoring at the top of both well casings showed combustible gas at non-detectable concentrations (less than 1 ppmv), and background air concentration of combustible gas away from the well casings was measured at 0.1 to 0.2 ppmv.

Results of the monitoring at the top of the well casings showed non-detectable concentrations of hydrogen sulfide. Results of the bubble leak-testing activity showed no dynamic bubble formation and therefore no indication of gas pressure leakage from the top of the well casing.

All work was performed under the supervision of a CalGEM representative.

Abandoned Oil Well Leak Test – Redondo Beach, CA

ABANDONED OIL WELL CONSULTATION, INSPECTION AND TESTING

Terra-Petra was recently hired to by the developer of a Redondo Beach property to consult on all California Department of Conservation, Geologic Energy Management Division (CalGEM) requirements associated with the potential discovery of an old abandoned oil well on their property.

Historical records and photos identified the oil well within the property boundaries, however, previous efforts to locate the well by the developer proved fruitless.

Once engaged by the client Terra-Petra employed our standard process for well locations which we call our “oil well due diligence”.

STEP 1 - Geophysical Survey

The first step in the process is to conduct a geophysical survey of the site. Oil Wells can be identified by the magnetic anomaly that shows up when conducting this work given that their casings are usually constructed of steel. Steel cased oil Wells have a specific “signature” that is very distinct from other metallic objects such as buried pipe or equipment. It becomes very apparent in the mapping system when an oil well is present.

STEP 2 - Oil Well Excavation

The second stage of the process is to physically locate the well by excavating and uncovering it. We inspect the integrity of the casing and the surface plug (if present). Once this is done, we notify the local CalGEM representative that we have located a well and that we will be conducting the leak testing.

STEP 3 - Oil Well Leak Test

We then conduct a leak test at the well casing to identify if any fugitive gasses are emanating from the casing. The precise location of the oil well is then surveyed in by our survey crew and plotted on a site plan per CalGEM’s standards.

STEP 4 - Final Inspection & Client Summary Report

Los Angeles was an oil town

Los Angeles Oil Drills Give Way to Skyline Views

(from Urbanize.LA)

One can also say that LA oil drills gave way to new skyline views as well as the birth of environmental engineering.

Long before becoming the epicenter for the film industry, Los Angeles was an oil town. Though few remnants remain today, a large oil field once cut a broad swath through the heart of Los Angeles, running from just south of present-day Dodger Stadium to Vermont Avenue in what is now Koreatown.  It began large-scale operations in the early 1890s, before peaking at the turn of the 20th century and falling into decline as development encroached into its territory over ensuing decades.

The photo (above) from the USC Digital Archive was taken near the intersection of Edgeware Road and Court Street in the first decade of the 1900s.  It depicts oil production in the Westlake area near the era’s peak.  Note the small home at 1274 Court Street at the terminus of Edgeware.  The after image below, taken in 2018 by Laurie Avocado, shows this same view in a modern context.  Gone are the abundance of oil drills, replaced by the skyscrapers of Downtown Los Angeles.  The lone remnant of the century-old image is that same house at 1274 Court Street.

UST abandonment status update – Los Angeles, California

The in-place UST abandonment went well this past week with a current Terra-Petra project in the Downtown Los Angeles area. LAFD Inspector Sanchez was satisfied with the procedure. Next step in the process will be to follow through with the soil borings, sampling and testing, and the investigative results shall be compiled in the UST Closure Report to LAFD.

Approximately 558,000 underground storage tanks (USTs) nationwide store petroleum or hazardous substances. The greatest potential threat from a leaking UST is contamination of groundwater, the source of drinking water for nearly half of all Americans. EPA, states, and tribes work in partnership with industry to protect the environment and human health from potential releases.

Successful Oil Well Re-Abandonment Work in Santa Fe Springs

Terra-Petra Oil Well Abandonment The end of August 2016 marked the commencement of Terra-Petra’s re-abandonment of a single oil and gas well located on a client’s property in Santa Fe Springs, California.

Terra-Petra managed all of the oil well permitting matters associated with an unspecified redevelopment of the site since March of this year — consulting with the property owner and negotiating with the Division of Oil Gas and Geothermal Resources (DOGGR) on all oil well related compliance matters in an attempt to bring the site up to current standards so that it can be redeveloped.

Terra-Petra provided a full turn-key approach to address the oil well compliance matters upon submitting the Construction Site Plan Review, wrote the well reabandonment program, filed for and received the Permit to Conduct Well Operations and currently in the process of re-abandoning the well. The well re-abandonment work typically consists of drilling out all existing cement plugs within the well all the way to depth.

Oil well re-abandonment

Once the well is cleaned out new “isolation plugs” consisting of cement are installed at varying depths to seal off different oil and gas producing zones including the upper hydrocarbon zone as well as the base of fresh water.

The cementing operations are completed with a final cement plug from 25’-35’ deep to the surface.  A steel plate is tack welded to the exterior steel casing and the last 5 digits of the API number are welded to it.

The well then must be surveyed prior to burying with latitude and longitude in a specific DOGGR approved format. Terra-Petra is anticipating a completion date of September 23, 2016. Please contact Terra-Petra for any of your oil well related needs.

Update on Terra-Petra’s Pacific City Oil Well Abandonment Project

Joe Morelli, Fire Protection Analyst of the HBDF, and Terra-Petra's Larry Barnes consulting near an abandoned oil well trenchNearly two years after commencing environmental work on the Pacific City project in Huntington Beach, California, the site is prepared for further construction. After intensive environmental work to verify the integrity of the on-site oil and water well abandonments, all necessary permits are in place to start constructing the foundation of the approximately 190,000 sq. ft. property. Terra-Petra is proud to have taken part in such a notable development project while contributing to tremendous cost savings for the client.

In order to bring incredible value to the project, Terra-Petra came to a practical remediation plan contradictory to one which may have been reached by blindly conforming to re-abandonment codes and procedures. After a careful review of all information obtained from field explorations and well documents from the DOGGR, Larry Barnes – Terra-Petra’s Senior Petroleum Geologist – determined that a minimally intrusive remediation approach would be sufficient for the site. This approach involved shortening all wells to a depth between 6 and 10 feet below grade, recapping each well head with a circular metal plate, and installing a methane mitigation vent cone at each well head. Rather than disturbing the abandoned wells and replacing all cement plugs with costly drilling expenses, this much more non-intrusive approach was deemed more than adequate for preventing any future leaks and site contamination.

In convincing the governing agencies that is safer to leave the wells relatively undisturbed and proceeding with the aforementioned action plan, Terra-Petra was able to successfully save the client millions of dollars while simultaneously reducing their risks on this sizeable development project. With the combined expertise of the construction team Terra-Petra was able to meet the expedited construction schedule. The client is now in the process of grading the site in preparation for foundation construction. Terra-Petra will be on hand to proceed with the necessary methane gas mitigation measures on the foundation of the site for the safety of future site residents.
