Estimating Production, Drainage Volume, And Interference From Multiple Stacked Wells: A Midland Basin Case Study

The Challenge

The dynamics of full-field development for multi-target Midland Basin acreage have a tremendous impact on the total EUR per section. Depletion can be hard to model and results are often only clearly seen after a significant amount of wells has been drilled. Traditional models assume unrealistic fracture geometries and do not account for the amount of variability in the geology.

The Solution

Using a FracStar® surface array, acoustic data were acquired during the treatment of an eight-well pad in three target formations. Microseismic events and the created fracture network were imaged and allowed for a realistic reservoir model due to the accurate modeling of the discrete fracture network, distinction between propped and unpropped fractures, and the calculated permeability enhancement due to the treatment. Microseismic–based reservoir simulation was then used to estimate production and understand the interference between wells.
