In 1932, Bill Lane and Walt Wells invented bullet gun perforating and formed the Lane-Wells Company in Vernon, California. They performed their first job on Union Oil's La Merced #17 well in Los Angeles. The company that would become Western Atlas (later Baker Atlas) grew quickly and added other wireline services, including the gamma ray log in 1939 and the neutron log in 1941, which were developed by Well Surveys Inc., an affiliated company. In 1948, a Lane-Wells crew performed the company's 100,000th job on La Merced #17, the site of the first perforating run.
In 1963, Baker Atlas predecessor Lane-Wells introduced the Neutron Lifetime Log service, providing the ability to detect oil through well casing, and initiating the line of Baker Atlas pulsed-neutron logging tools for cased hole logging and reservoir monitoring. It took another five years for competitors to introduce a comparable service. Beginning in 1948, Well Surveys Inc. physicist Arthur Youmans led the team of engineers and scientists to develop this technology. The highly complex instrument included a miniaturized particle generator and sensors to detect and analyze sub-atomic particles. Mr. Youmans went on to become Vice President of Research and Engineering for Dresser Atlas.
In 1968, Lane-Wells and the Pan Geo Atlas Corporation (PGAC) merged to form Dresser Atlas, a name chosen to “position” the company as more than a perforating provider and as part parent company of Dresser Industries. A competitor with Lane-Wells but possessing deeper expertise and an international reputation in open hole logging, PGAC was the perfect merger partner to form an integrated wireline services company. Since its inception, Lane-Wells had generated most of its income from perforating services, but log interpretation had narrowed down producing zones, resulting in fewer perforations and less revenue. During the oil slump of the 1999, Western Atlas was acquired by Baker Hughes and the wireline division was created within the company rebranded as Baker Atlas. Western Geophysical was meanwhile allied with GecoPrakla of Schlumberger and later combined into a separate business entity called WesternGeco.
