Application of Grading Technology of Injection-Production Reallocation in Oil Sands Developed by SAGD: A Case Study in Longlake Oilfield, Canada
Springer Series in Geomechanics and GeoengineeringProceedings of the International Field Exploration and Development Conference 2019(2020)
Abstract
In the SAGD development process of oil sands in Longlake oilfield, Canada, there exists some problems such as large injection and production difference among wells and steam ineffective circulation. Through comprehensively considering geology, production, facility and economic factors, differentiation reallocation is conducted from single well to oil drainage area, and to the whole oilfield.
