International Standard
75.020 Extraction and processing of petroleum and natural gas
This International Standard is designed to provide guidance for improvement of the heavy oil recovery by thermal method.This standard provides content and requirements for the design of Multi-component thermal fluid huff and puff production in heavy oil fields with complicate reservoir conditions including thin layers, thick layers, edge and bottom water as well as medium/deep layers. The standard is applicable to the full development cycle. It is proposed to standardize the design of Multi-component thermal fluid huff and puff process scheme to ensure the reliability and effectiveness of implementation, and ultimately improve the oil production and recovery rate.
