General Meeting: Diagnostic Driven Multiphase Well Performance Analysis and Production Forecasting

May 15 @ 11:30 AM - 1:00 PM



Diagnostic Driven Multiphase Well Performance Analysis and Production Forecasting



This presentation focuses on diagnostics driven multi-phase well performance analysis and production forecasting methods in unconventional (low-permeability) reservoirs.  We will provide background for recently introduced methodologies adapted/developed for unconventional reservoirs including basis for selecting/identifying decline parameters.  This presentation will primarily include examples from various basins illustrating methods for forecasting gas-oil ratio, evaluating multi-phase behavior and addressing challenges associated with significant changes in well performance such as fracture-driven interactions, refracturing, etc. We will finally discuss applications, limitations associated with those methodologies.



Dilhan Ilk is an Executive Vice President and Manager of the North America Division at DeGolyer and MacNaughton. Dr. Ilk earned a bachelor’s degree in petroleum engineering in 2003 from Istanbul Technical University. In 2005, he received a master’s degree in petroleum engineering, and in 2010 he was awarded a doctorate in petroleum engineering, both from Texas A&M University.  He manages projects including independent evaluations of reserves and resources. He specializes in assisting clients with the assessment of unconventional resources and well performance evaluation and forecasting using a systematic workflow that combines diagnostic methods with analytical and numerical techniques. He is a registered professional engineer in the State of Texas.


He is a member of SPE Reservoir Description and Dynamics advisory committee, and currently he is the chair of Well Performance sub-committee of the SPE Reservoir Description and Dynamics advisory committee. He is a contributing author of the SPEE Monograph IV—Estimating Ultimate Recovery of Developed Wells in Unconventional Reservoirs and SPE PRMS Applications Guidelines (2022). He was co‑editor of the SPE digital publication series “Performance Forecasting in Shale Reservoirs.”
