“…The Tarim Oilfield and Southwest Oil and Gas Field in China have initially developed relevant technologies for integrity evaluation of deep gas wells, and have explored quantitative evaluation of integrity [2] . After 2000, major oil field companies and related institutions around the world have successively conducted research on gas well integrity evaluation and management technology [3][4][5][6][7][8][9][10][11] . Most gas wells will experience annular pressure after completing oil testing.…”

Safety management of high-pressure gas wells is a prerequisite for ensuring the safe production of high-pressure gas wells. In recent years, with the continuous production of high-pressure gas wells in front of Kuqa Mountain, some gas wells have experienced abnormal annular pressure, which has increased the risk of gas well management. The key points of high-pressure gas well production management are to determine the range of annular pressure control, determine the safety status of abnormal pressure wells, and ensure long-term safety production of high-pressure gas wells. Due to insufficient understanding of these risks in the early stage, effective measures were not taken during the oil testing design and construction process, resulting in multiple high-pressure gas wells experiencing incidents such as tubing string failure and casing deformation during the oil testing process, resulting in operation failure or even scrapping. This article evaluates the annular pressure and control mechanism of high-pressure gas wells based on the current concept of integrity, which cannot meet the complex factors of high-pressure gas wells, and combined with the characteristics of high-pressure gas reservoirs in front of Kuqa Mountain;

Workover and Completion Operations in East Java Sour Gas Field, Indonesia

et al. 2012

View full text Add to dashboard Cite

Nowadays many exploration and production companies have high interest in producing deep, high pressure gas reservoirs that contain sour gas. Carbonates in East Java, Indonesia faced challenges related to workover and completion operations that are prone to kick-loss cycles based on the drilling experiences.The presence of hydrogen sulfide (H 2 S) and carbon dioxide (CO 2 ) in the formation made the completion operation dangerous and difficult to be carried out in the field where is adjacent to a populated area, thereby increasing the requirement and need to prevent the release of sour gases during completion operations.
