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

Excavated top of well casing cleaned and prepped for 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

Mapping the long history of oil drilling in Los Angeles

Re-Post of original article on Curbed Los Angeles

Los Angeles has had always had a complicated relationship with oil. In 1892, what had been a small agricultural city popular with Midwestern tourists became a boomtown nearly overnight when oil was discovered in modern-day Echo Park.

From the beginning, the needs of the oil drillers collided with those of residents, visitors, and developers. The city we know today grew up alongside the oil industry and continues to be shaped by it—about 3,000 active wells remain in LA County, many of them in close proximity to residential neighborhoods, parks, and schools.

LA Curbed mapped a few of the places that show how the industry has embedded itself into the urban environment of Los Angeles.

1. Echo Park Deep Pool

1419 Colton St
Los Angeles, CA 90026
(213) 481-2640

Visit Website

Here’s where it all began—yes, here. The current site of the Echo Park Deep Pool is where Edward Doheny and his partner Charles Canfield drilled the first oil well in Los Angeles in 1892, using a sharpened eucalyptus tree. According to lore, they found the site after Doheny spotted a slick black substance on the wheel of a passing cart. As casually as possible, he asked the driver to show him exactly where he had come from.

2. Discovery Well Park

2200 Temple Ave
Signal Hill, CA 90755
(562) 989-7330

Visit Website

A plaque and adjoining park commemorate the first productive well drilled at Signal Hill. On June 23rd, 1921, a geyser of oil erupted from the Alamitos number one well, leading to an explosion of drilling in the Long Beach area. By 1923, Signal Hill was the state’s largest field, and California was producing a quarter of the world’s supply of oil. Per the plaque, the monument is a “tribute to the petroleum pioneers for their success here, a success which has, by aiding in the growth and expansion of the petroleum industry, contributed so much to the welfare of mankind.” We’ll take their word for it.

3. Pico Canyon Oil Field

Doheny may have set off the oil boom within the city of Los Angeles, but the first successful well in LA County was to the north, in the Santa Susana Mountains. A gusher at Charles Mentry’s Pico Well No. 4 on September 26, 1876, announced to the world that Southern California was rich in black gold. The nearby town of Newhall later became home to the state’s first refinery (pictured below).

4. Phillips 66 Oil Refinery

1660 W Anaheim St
Wilmington, CA 90744

The massive Wilmington Oil Field is the largest in California, having produced somewhere between 760 million and 1.2 trillion barrels of oil since it was first tapped in 1932. The Phillips 66 refinery in the southeast Los Angeles neighborhood paints one of its massive storage tanks orange  every October as a strange and festive Halloween tradition.

5. Andeavor Refinery

22600 S Wilmington Ave
Carson, CA 90745
(310) 816-8100

Visit Website

Perhaps the most recognizable oil facility in the world, the Andeavor Refinery in Carson is adorned with an enormous American flag easily visible to drivers on the 405. Like Andeavor’s Wilmington refinery, this one dates back to the region’s oil boom of the 1920s and 1930s. Together, the two facilities now process a combined 380,000 barrels daily.

6. THUMS Islands

(562) 786-2385

Visit Website

At the southeastern end of the Wilmington field is are the THUMS islands, constructed by the Texaco, Humble, Union, Mobil and Shell oil companies in 1965. As part of an agreement with the city of Long Beach, the oil companies invested considerable funds in disguising the drilling sites with boulders, palm trees, sculptures, and water falls—so much so that they are sometimes mistaken for luxury resorts.

7. Venice Beach

Venice Beach
Los Angeles, CA

Starting in the 1930s, Venice had a run as one of the leading oil producers in the state. During that time, derricks ran all along the canals and dotted the beach. Waterways became filled with oily sludge and the ocean was badly polluted. Production eventually dropped off in the 1970s and the last wells in the area were capped less than two decades later.

8. Inglewood Oil Field

College Blvd
Culver City, CA 90230

The enormous Inglewood Oil Field was first tapped in 1924 and has produced close to 400 million barrels of oil since then. Despite years of complaints from nearby residents, hundreds of wells continue to operate daily right alongside its neighbors in Baldwin Hills and Culver City.

9. False building

1351 S Genesee Ave
Los Angeles, CA 90019

From the outside this edifice looks like a particularly soul crushing office building with no windows. Inside, however, it’s not a building at all. The structure is simply a shell disguising the site of an oil derrick slurping away at the Beverly Hills Oil Field.

10. Beverly Hills High School

241 S Moreno Dr
Beverly Hills, CA 90212
(310) 229-3685

Visit Website

One of the smaller major oil fields in the Los Angeles area, the Beverly Hills field is nonetheless productive, and the oil derrick on the campus of Beverly Hills High School was, until recently, churning out about 400 barrels of crude each day. The drilling site was ordered shut in 2016 and the complicated process of cleaning it up is scheduled to start this month.

11. Salt Lake Oil Field

6298 W 3rd St
Los Angeles, CA 90036
(323) 936-2864

Visit Website

The Grove and Original Farmers Market today sit atop the Salt Lake Oil Field, discovered by dairy farmer Arthur Gilmore in the mid-1890s. Though the field was most productive in the early 20th Century, it was still being tapped in 1985, when drillers inadvertently caused methane gas to move below ground, rising up to the surface within the Ross store at Third Street and Fairfax Avenue. The resulting explosion injured 23 people.

12. Jefferson Drill Site

1375 W Jefferson Blvd
Los Angeles, CA 90007

The subject of significant community opposition, this South LA drill site was forced last year to comply with city-imposed requirements that ensure its operators enclose the site and monitor vibrations and noxious fumes that neighbors say are caused by the drilling.

13. Del Amo Field

It might not look like it, but this quiet residential street in Torrance was the site of the first major strike in the Del Amo oil field. Throughout the 1920s, this was one of the most productive fields in the LA area with nearly 1,500 wells spread across more than 3,500 acres.

14. Huntington Beach

Offshore oil rigs are a familiar sight to Huntington Beach residents and visitors. On and off land, drillers have been tapping the city’s oil field since the 1920s. Recent research from the U.S. Geological Survey suggests that it may, in fact, have been oil drilling here that triggered the Long Beach Earthquake in 1933.

TERRA-PETRA ELD

The Use of Electronic Leak Detection (ELD) on Waterproofing Membranes over Concrete Surfaces

Waterproofing membranes are a key element in building enclosure systems—a key element that ultimately gets covered up by a variety of finish materials including landscaping, green roofs, topping slabs, pavers and so on. As most of us know, excavation to expose a failed waterproofing membrane for repairs can be prohibitively expensive and in some cases impossible. For this reason, many designers are choosing to specify integrity testing to verify that the waterproofing membrane is free of discontinuities and penetrations through the membrane prior to the installation being permanently covered. When integrity testing is not specified, many contractors are often performing this type of testing voluntarily to avoid future problems or “call-backs.”

The most common integrity testing method is the flood test. Flood testing is typically performed by flooding waterproofed horizontal surfaces with at least two inches (50 mm) of water for a period of up to 48 hours. Temporary dams are often constructed to partition the test areas, provide an up-turned plaza edge and control the depth of the flood testing. During the flood test, access to the underside of the flooded areas is necessary for a visual inspection of water leakage. However, in the case of a membrane failure (leak), flood testing indicates only where water is penetrating through the entire assembly within the test area, not the location above where water is breaching the membrane. In addition, flood testing cannot be performed on vertical surfaces or at locations where the underside of the slab is not accessible.

The aforementioned restrictions and lack of conclusive data associated with flood testing has enabled Electronic Leak Detection (ELD) to gain momentum as a viable alternative to traditional flood testing. This article will focus on the different types of ELD and the applications where ELD is or is not well-suited.

California Commercial Real Estate Unchanged Following Election – Read Survey

The introduction to this survey is provided by John M. Tipton Partner, Real Estate Department Allen Matkins:

Allen Matkins and UCLA Anderson Forecast have partnered to create a Commercial Real Estate Survey and Index to better predict future California commercial rental and vacancy rates. This tool surveys supply-side participants – commercial developers and financiers of commercial development – for insights into their markets. The Survey and the resulting Index provide a measure of the commercial real estate supply-side participants’ view of current and future conditions. Since participants make investment actions based upon these views, it provides a leading indicator of changing supply conditions.

Allen Matkins sponsored this Survey to provide value to the industry. Partnered with UCLA Anderson Forecast, the leading independent economic forecast of both the U.S. and California economies for over 65 years, they have tapped the knowledge of the leading developers and financiers of real estate development in California to provide the best, clear-sighted forecast of the California commercial real estate industry.
