Abstract

Numerical simulation of complex geological formations can be simplified using a series of 1D geological models as an approximation to the formation. Assuming the existence of a known 3D formation geometry, the first step in the approximation is to obtain a curtain section along the path of a proposed or actual well. The curtain section is a vertical slice through the formation that intersects the well path along its length. This first step provides a 2D approximation to the formation near the borehole. Using this 2D approximation, a series of 1D approximations are generated by taking vertical slices perpendicular to the horizontal direction of the wellbore. The resulting models are used as input for 1D numerical simulations can be significantly faster than performing 3D modeling in the original formation. The speed and accuracy of the method is consistent with the requirements for simulations used to assist in geosteering.
