Abstract

This paper presents a discussion of the pressure-transient responses of horizontal wells in anticlinal structures and curved wells in flat reservoirs. It is shown that, in the absence of gas cap, conventional horizontal-well models may be used to approximate the flow characteristics of the systems where the trajectory of the well does not conform to the curvature of the producing structure. If a gas cap is present, however, the unconformity of the well trajectory and producing layer manifests itself especially on derivative characteristics when the gas saturation increases around the well. In general, the most significant deviations from the conventional horizontal-well behavior are observed during the buildup periods following long drawdowns. In these cases, the pressure-transient analysis is complicated and requires detailed numerical modeling of the well and reseryoir curvature in the vertical plane.
