Author of the Book “Fundamentals of Gas Lift Engineering: Well Design and Troubleshooting” Gulf Professional Publishing, Elsevier, 2016.
Design of high-rate, MRC, extended-reach wells:
Dynamic simulations using Dynalift to determine the range of the operating gas injection pressure to avoid gas lift instabilities and provide flexibility to handle water cuts from 0 to 100% with a single gas lift valve design as well as to avoid instabilities due to valve interference during the unloading process to increase the life of the subsurface gas lift valves.
Chairman of API task group for the development of RP 11V10 (Recommended Practice for Intermittent Gas Lift).
Brown field network simulations using PIPESIM-NET.
Development of the following analytical and operational tools:
New mechanistic model for the dynamic behavior of gas lift valves for continuous flow.
Functional relationship for liquid fallback prediction and the dynamic behavior of gas lift pilot valves for intermittent gas lift.
Design of a new type of insert chamber capable of handling high formation gas/liquid ratios.
New mechanistic model for gas chamber pumps.
New design and optimization procedure for dual completions.
New field procedure and method of analysis for downhole pressure surveys for intermittent gas lift.
