Western Geophysical
Western Geophysical was an international oil exploration company founded in California in 1933 by Henry Salvatori for the purpose of using reflection seismology to explore for petroleum. The company prospered and was sold by Salvatori to Litton Industries in 1960. In 1987, Litton and Dresser Industries formed a joint venture comprising Western and Dresser Atlas. The joint venture, Western Atlas, was spun off as a public company in 1994. Western then purchased Halliburton Geophysical Services, which had been formed from Geophysical Service Incorporated, Geosource and several other companies. In 1998, Western Atlas was acquired by Baker Hughes. In 2000, Western Geophysical became part of a joint venture between Baker Hughes and Schlumberger Schlumberger Limited (), doing business as SLB, is an oilfield services company.

Clarence Karcher, John Clarence Karcher and Eugene McDermott in 1930 for the purpose of using refraction and reflection seismology to Hydrocarbon exploration, explore for petroleum deposits. History On December 6, 1941, the company was purchased by Eugene McDermott, Cecil Howard Green, J. Erik Jonsson, and H.B. Peacock. During World War II, the company produced submarine detection devices. In 1951, the company was renamed Texas Instruments (TI) with GSI as a division.

After several years of losses in 1994 Halliburton sold ...

Oilfield Services Companies
A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations. Such reservoirs form when kerogen (ancient plant matter) is created in surrounding rock by the presence of high heat and pressure in the Earth's crust. Petroleum reservoirs are broadly classified as ''conventional'' and '' unconventional'' reservoirs. In conventional reservoirs, the naturally occurring hydrocarbons, such as crude oil or natural gas, are trapped by overlying rock formations with lower permeability, while in unconventional reservoirs, the rocks have high porosity and low permeability, which keeps the hydrocarbons trapped in place, therefore not requiring a cap rock. Reservoirs are found using hydrocarbon exploration methods. Oil field An oil field is an area of accumulation of liquid oil underground in multiple (potentially linked) reservoirs, trapped as it rises by impermeable rock formations. In industrial terms, an o ...

Technology Companies Disestablished In 2000
Technology is the application of knowledge to reach practical goals in a specifiable and reproducible way. The word ''technology'' may also mean the product of such an endeavor. The use of technology is widely prevalent in medicine, science, industry, communication, transportation, and daily life. Technologies include physical objects like utensils or machines and intangible tools such as software. Many technological advancements have led to societal changes. The earliest known technology is the stone tool, used in the prehistoric era, followed by fire use, which contributed to the growth of the human brain and the development of language in the Ice Age. The invention of the wheel in the Bronze Age enabled wider travel and the creation of more complex machines. Recent technological developments, including the printing press, the telephone, and the Internet have lowered communication barriers and ushered in the knowledge economy.
