Presentation Summary:

California and the Los Angeles Basin were once the epicenter of the United States oil industry,

contributing over one-third of all American oil production in 1923. Although local production has

dropped dramatically, reminders of this oil boom are present around and underneath us.

Developers have found wealth, along with a few land mines (idle and abandoned wells), in the

vacant lots that were the site of significant oil production. These developers and the associated land

use authorities need the expertise of knowledgeable engineers and geologists as they look to avoid

or abandon / reabandon these oil wells and provide the residential and commercial development

needed in our state. The goal of this talk is to give a brief insight into the history of oil development

in the Los Angeles Basin; provide guidance on how to locate the wells that stand between vacant

lots and development; and give a high-level look at the effort required to initiate the abandonment

or reabandonment of these wells.

 
Speaker Biography:

Mr. Thomas Walker developed an early interest in the energy industry growing up in Tyler, Texas, as

the son of a petroleum geologist, and began working in oil and gas as a student in 1980. After

earning a Bachelor of Science in Petroleum Engineering (cum laude) from Texas A&M University in

1985, he joined Mobil Oil Corporation as a field petroleum engineer. Early in his career, he

contributed to the development of an economic model for the Luling Branyon oil field during a

major oil price downturn, an experience that set the foundation for his expertise in oil and gas

property valuation. In 1991, he relocated to the Los Angeles Basin with Mobil, where he gained

regulatory experience as an Environmental, Health and Safety Engineer. He transitioned to

consulting in 1999, founding Walker Engineering, Inc., which later became Evans & Walker following

a partnership formed in 2001. Based in the Los Angeles Basin for more than 35 years, he has built

extensive experience in urban oil and gas operations. Outside of work, he lives in Huntington Beach

with his family and has been deeply involved in community service, youth sports, scouting, and his

church.
