The highly prosperous Western region of Egypt comprises the Bahariya Formation (Upper & Lower) and Abu Roash sands across multiple fields (such as the Abrar and Silah). These unconventional resource plays are extremely heterogeneous and exhibit variation, both vertically and spatially, over short distances. Such heterogeneity poses a challenge in optimizing completion and stimulation designs for wells targeting low and ultralow permeability plays. Simplistic workflows do not suffice for optimum stimulation. This paper discusses the application of suitable workflows that follow a data driven approach for stimulation design in such heterogeneous reservoirs.
