ITERATIVE TECHNIQUE TO DETERMINE RESERVOIR AND FRACTURE PROPERTIES USING BUILDUP DATA FOR HYDRAULICALLY FRACTURED WELLS. Conference Paper uri icon

abstract

  • This paper presents a new iterative technique for interpreting early time pressure buildup data for hydraulically fractured wells. The technique uses a modified square-root-of-time analysis with permeability and fracture length correction curves generated from Cinco's solution to flow equations for finite-conductivity fractures. The method is applicable to low permeability reservoirs where conventional methods of analysis are difficult to apply. The authors demonstrate how buildup tests dominated almost totally by bi-linear flow can be rigorously evaluated using their model. The model provides estimates of fracture conductivity, fracture length and formation permeability using data before pseudolinear flow is achieved.
