2026-2027 SPE Distinguished Lecturer Series:
Lecture Title: Accelerated Learning in the Unconventionals Through Integrated Field Experiments with Instrumented Monitor Wells
Lecturer: Tim Benish, ExxonMobil
Abstract:
This presentation will provide an overview of unconventional field experiments conducted in recent years to measure fracture dimensions, that when combined with production analysis, can support and inform development decisions to avoid overcapitalization from suboptimal spacing, stacking, or stimulation choices. Specifically, it will highlight the benefits of dedicated monitor wells equipped with fiber optics and pressure gauge arrays to interrogate the three-dimensional fracture network. Pressure measurements integrated with fiber optic measurements provide a holistic interpretation of the extent and heterogeneity of the stimulated rock volume.
Vertical monitor wells are effective in determining the overall height of the created fractures as well as the drainage boundaries of individual benches. Slant monitor wells extend these measurements of fracture density and depletion at varying distances from a stimulated well to enable mapping of the fracture drainage network. Systematic variation of the completion design along the treatment well adjacent to a slant monitor well can be implemented to directly compare the efficacy of treatment design options in the same well.
Typically, well spacing and completion design are decided iteratively using well-level production, which is time intensive and often leads to inconclusive results. While challenging to execute, diagnostic monitor wells provide definitive measurements of fracture dimensions, including their extent, variability, and associated depleted rock volume. This understanding delivers the clear direction needed for well placement and completion design decisions early in the asset development cycle so as to create the greatest value.
Bio:
Tim has a Bachelor degree from Georgia Tech and a PhD from MIT in Chemical Engineering. Starting at ExxonMobil in 1999, heβs had assignments spanning U.S. unconventional completions, Russian shale exploration, Norwegian subsea completions, and research on deepwater and unconventionals technologies with a recent focus on fracture diagnostics. He is currently the Hydraulic Fracturing Principal for ExxonMobil.
