Overview
Weatherford International is a multinational oilfield services company serving oil and natural gas operators and other energy customers. Its portfolio covers the principal stages of the well life cycle: drilling and well construction, formation evaluation, completion, production optimization, and intervention. The company supplies specialized tools, systems, software, and field services rather than producing hydrocarbons itself. The modern company was established in 1987 as Energy Ventures, an enterprise that developed from an earlier exploration and production business. Its corporate and commercial roots reach back to 1941, when Jesse E. Hall Sr. founded Weatherford Spring Company in Weatherford, Texas. The business subsequently expanded through a large number of acquisitions, with the reference material describing more than 300 acquisitions over its development. It adopted the EVI name in 1990 and became Weatherford International in 1998. During the late 1990s and 2000s, Weatherford pursued rapid expansion through acquisitions and organic investment. Unlike some competitors that concentrated heavily on new-field development, it placed significant emphasis on mature fields and on technologies intended to improve recovery, extend well productivity, and manage increasingly complex well conditions. Its activities included drilling tools, tubular-related businesses, evaluation technologies, completion systems, artificial-lift equipment, production services, and intervention capabilities. The company reported particularly strong growth during the period from 1999 through 2008, when it expanded its international presence and reached almost US$10 billion in revenue in 2008; that figure is historical and is not treated here as a current financial measure. Weatherford also went through several changes in legal domicile and corporate structure. It announced a move of incorporation from Bermuda to Switzerland in 2008 and later announced plans to relocate its legal domicile to Ireland in 2014, while maintaining major operational activities in Houston. The company’s international footprint has included oil- and gas-producing regions across the Americas, Europe, the Middle East, Africa, and Asia-Pacific, with the cited reference describing operations in approximately 75 countries. Heavy debt and industry pressures eventually led to a major restructuring. Weatherford and two subsidiaries filed for protection under Chapter 11 of the United States Bankruptcy Code in July 2019. The company completed its restructuring and emerged in December 2019 with a revised capital structure and new financing facilities. The process reduced approximately US$6.2 billion of funded debt and provided additional exit financing and liquidity, according to the company’s restructuring announcement. Following executive changes in 2020, Girish K. Saligram became president and chief executive officer in October of that year. Weatherford’s ordinary shares returned to Nasdaq trading on June 2, 2021, under the ticker WFRD, after the company’s application for relisting was approved. Weatherford remains an active oilfield services provider, with its business positioned around technical specialization, equipment reliability, production enhancement, and digitally supported well-life-cycle management.
History
Weatherford’s corporate history combines a Texas oilfield-services heritage with a later multinational expansion strategy. Jesse E. Hall Sr. founded Weatherford Spring Company in Weatherford, Texas, in 1941. That business established the historical roots of the Weatherford name, although the modern publicly traded oilfield-services company was formed later. In 1972, Energy Ventures was created as an exploration and production company. In 1987, the enterprise was reorganized or established as the company that would develop into the modern Weatherford business. Bernard J. Duroc-Danner was recruited to build oilfield equipment and services operations, shifting the organization toward a broader service-company model. The company was initially known as Energy Ventures, adopted the EVI name in 1990, and changed to Weatherford International in 1998. From 1999 through 2008, Weatherford expanded rapidly through acquisitions and internal growth. The company ultimately became an amalgamation of more than 300 acquisitions, adding technologies, equipment lines, geographic coverage, and specialized field capabilities. Its strategy emphasized mature oil and gas fields, where operators sought to maintain or improve output from existing assets. This focus differed from the sector’s prevailing emphasis on new-field development and gave Weatherford a substantial role in production enhancement and well-life-cycle services. In 2001, Weatherford separated its tubulars business from its core offerings. The stated rationale was that the business required substantial capital and could constrain investment in areas such as formation evaluation, well construction, and production. The company continued expanding through the following decade and reported growth of more than 20 percent per year during the period described in the reference material. Revenue approached US$10 billion in 2008. The company’s legal structure changed as it internationalized. Weatherford announced a move of its place of incorporation from Bermuda to Switzerland in 2008. In April 2014, it announced that its board had approved moving the legal domicile to Ireland, while its operational office remained in Houston, Texas. The company continued to serve oil- and gas-producing regions worldwide, eventually describing a presence in about 75 countries. Weatherford faced regulatory criticism over activities connected with sanctioned countries. In relation to Cuba, United States authorities alleged that the company and P.D. Drilling Holdings supplied products containing US goods and used misleading shipping documentation. In 2007, media reports and investors also questioned operations conducted by a foreign subsidiary in Sudan. Weatherford responded by announcing a withdrawal from foreign-subsidiary operations in countries sanctioned by the United States and exited Sudan in 2008. The company donated equipment and additional support to a humanitarian organization working in the country. Separate reporting from the Paradise Papers identified certain Weatherford subsidiaries among offshore entities in Barbados. Financial pressure and industry conditions culminated in a Chapter 11 filing in July 2019 by Weatherford International and two subsidiaries in the Southern District of Texas. The petitions reported assets exceeding US$1 billion. Weatherford completed its financial restructuring in December 2019 and emerged from bankruptcy protection with a substantially revised balance sheet. The company reported reducing approximately US$6.2 billion in funded debt, arranging US$2.6 billion in exit financing facilities, establishing a US$195 million letter-of-credit facility, and retaining US$900 million of liquidity. Leadership changed significantly in 2020. Mark A. McCollum and chief financial officer Christian Garcia resigned, Karl Blanchard served as interim chief executive officer, and Charles M. Sledge became board chairman. Girish K. Saligram was appointed president and chief executive officer, effective October 12, 2020, and also joined the board. In 2021, the company returned its ordinary shares to Nasdaq trading under the symbol WFRD. Weatherford continues as an active oilfield-services company focused on technologies and services for drilling, evaluation, completion, production, and intervention.
