Significant volumes of hydrocarbons have been discovered in Upper and Lower Wilcox reservoirs in the Gulf of Mexico (GOM), typically consisting of stacked sets of lower-permeability sandstones. Several of these discoveries have been developed successfully using cased-hole vertical wells and single-trip multizone frac-pack completion systems. The complete paper describes an alternative lower‑completion concept for developing these reservoirs referred to as high-angle multifractured (HAMF) well design. The value of the HAMF concept was assessed with reservoir modeling to understand its value for low-mobility reservoirs.
Introduction
A key feature of these low-mobility Wilcox reservoirs is that they often consist of multiple stacked sets of individual sand bodies rather than only a single-sand, high-mobility reservoir.
