Offset steam injection shut-in guidelines during drilling operations: south belridge field case study

摘要

Offset steam injection wells within a certain radius are typically shut in within a certain time period before drilling an in-field (increased density or replacement) well. The basis of this practice is that the reservoir pressure will eventually decrease to a minimum value, allowing drilling to proceed without problems. A study was undertaken to develop injection shut-in guidelines which consider specific reservoir conditions such as pressure, pattern size, and steamflood maturity.
