Determination of Individual Layer Properties by Layer-by-Layer Well Tests in Multilayer Reservoirs with Crossflow

Abstract

An interpretation theory is given for drawdown and buildup tests, which are given to an individual layer of a multilayer reservoir with crossflow. The crossflow behavior and its influence on drawdown and buildup curves are discussed. It is found that both drawdown and buildup curves have two straight lines with a transition period between them. The first straight line corresponds to the period when the well test theory for a single-layered reservoir is effective for an individual-layer test in a multilayer reservoir with crossflow. The first straight line determines the kh product and the skin factor of the ...
