MMG's Hotbay oilfield won nearly 100 tons of high-yield oil flow
News from <url> (correspondents Liu Dongzhou, Yuan Zhiming, Zhou Tianwei, Hou Dongdong) On April 14th, the 7772 well of the development evaluation well deployed by China Petroleum (Kazakhstan) Mangeshtao Company (MMG for short) in the deep-seated Rydebai oilfield won 99.83 tons of self-injection oil flow.This is the third development evaluation well implemented after the 7770 and 7771 wells deployed last year were discovered by industrial oil flows, marking another breakthrough in supplementary exploration in the Hotbay oilfield.
MMG has steadily produced more than 6 million tons of crude oil for three consecutive years. The Hotbay oilfield is one of its two main oil fields, with an annual output of 2.06 million tons of oil in 2023.The oilfield was put into development in 1969, and the degree of recoverable reserves is as high as 70%. There are thousands of development wells densely distributed in the only 97 square kilometers of development rights, making it extremely difficult for the oilfield to stabilize production in the future.MMG company relies on supporting technologies related to the integration of exploration and development by the Chinese side, and takes the research on “new understanding of the development strata, new deep goals and new areas of encirclement” as its guiding ideology, and strives to carry out supplementary exploration work in the old oil fields.
The Development Department of CNOOC International has organized project companies and research institutes to demonstrate the deep potential of the Hotbay oilfield many times, and proposed a deployment plan for the trap goal of “low-amplitude structure + lithology”.Using the surrounding oil wells, key technical support units were organized to carry out work such as small-pitch mapping and reservoir prediction, and the best well position was selected in the target area, and 7772 wells were successfully deployed.
The precise digging potential of the 7772 well has rejuvenated the 55-year-old oilfield and made new contributions to the company's quality and efficiency.
