"Chevron now joins the ranks of the ultramajors", Roy Martin, an analyst at Wood Mackenzie Ltd., said in a note.
Shell was seen as the leading contender to buy privately owned Permian producer Endeavor Energy, people familiar with the transaction told Reuters, but the two companies have, so far, failed to agree on Endeavor's valuation.
The transaction will broaden the second highest US vitality firm's operations in USA shale oil and gasoline manufacturing, offshore drilling and liquefied pure fuel exports.
When the organization of oil-producing states released its monthly report this week, it revealed that energy output from OPEC had declined to levels not seen since early 2015. Once the transaction closes the combined entity will be run by Chevron CEO and Chairman Michael Wirth. Chevron also expects shale to generate profits for its pipeline, trading and refining units.
The deal may put pressure on Shell to seek assets in the Permian, where the Anglo-Dutch company has said it wants to grow. Chevron would also assume $15 billion in debt.
Shares of Anadarko jumped 33% Friday, while Chevron's stock fell 5%.
An increase in share buybacks from $4 billion to $5 billion per year.
USA crude was selling for almost $65 per barrel Friday.
BP Plc and Royal Dutch Shell Plc, which lag peers like Exxon and Chevron in the Permian, could make acquisitions to gain more exposure to the formation, analysts said.
Shale and Tight. The combination of the two companies will create a 75-mi-wide corridor across the most attractive acreage in the DE basin, extending Chevron's leading position as a producer in the Permian basin.
Measured by cash flow, Chevron said in a statement it would have generated a combined US$36.5 billion with Anadarko previous year, slightly ahead of Exxon's US$36 billion.
The Chevron executive is detailed-oriented and a relentless worker, said Mike Sommers, president of industry group American Petroleum Institute, where Wirth is a member of the executive committee. He estimated Chevron is paying about $50,000 an acre for Anadarko's west Texas holdings.
Mr Nicol said these attributes are particularly useful in the Permian, which requires more drilling than other leading shale basins because it is larger and also because it is imbued with layers of hydrocarbon, piled one on top of each other. But in general, Flynn said he expects positive things.
Expenses from that project are expected to reach $4bn over several years.
"This deal seems flawless".
In an indication of the worth the business locations on Anadarko's property, fellow mini-main Occidental Petroleum tried to purchase the corporate, sources instructed CNBC's, David Faber.
Occidental Petroleum Corp had made a US$70 per share bid for Anadarko and it is now weighing whether to move forward with a counter offer, a person familiar with the matter said.
