MEASURING EFFECTIVE FRACTURE HALF-LENGTH AND QUANTIFYING FLUX DISTRIBUTION IN AND AROUND FRACTURES IN PETROLEUM RESERVOIRS

摘要

Flux distribution along a fracture plane in a subsurface reservoir hydrocarbon containing formation is determined, and an effective half-length of the fracture is also determined. Previously, flux distribution along such a fracture plane has been considered uniform, in what were termed infinite conductivity fractures. The fracture half-length is calculated at a distance along the fracture from the wellbore where change in pressure (across the fracture plane) approaching zero. The results obtained according to the present invention are used for reservoir production planning and management.
