Abstract
Horizontal wells possess great potential for increasing productivity and are becoming the well of choice throughout the world. When a horizontal well cuts water, it often is catastrophic and may inhibit oil production, which is especially disappointing in a newly drilled well.
This presentation disseminates the mechanisms of water production and their effect on production decline in horizontal wells. Key problems and challenges in developing viable water shut-off (WSO) solutions for the various horizontal well completions are discussed.
Selected case examples of water shut-off are shown to illustrate key elements of implementing successful treatments. In addition the use of stimulation in combination with water control will be addressed, as well as some technology gaps.
A recommended approach is a combination of Reservoir Diagnostics, Reservoir Evaluation, Water Control and Stimulation for reducing excessive water production and improving oil and gas production. This methodology will be used throughout the presentation.
"WHAT IS ONE IDEA FOR TAKE AWAY?" There is no "magic" about Water Control, but engineering of Production Improvement water inflow management.
Biography
Keng Seng Chan is currently a Principal Reservoir Engineer for Petroleum Management Unit in Petronas. He is a recognized expert and invited lecturer in the oil and gas industrial on formation damage, matrix stimulation, down-hole scale, reservoir and production water control.
He had held various research and development, technology management, field operation technical support positions through out his 33 years career in the oil industry. With Sohio Petroleum Company, he served as a group leader for EOR and waterflood conformance research team and developed a unique seawater surfactant caustic flood system for Prodhoe Bay Alaska fields. With Schlumberger, he had participated in several key developments of new and innovative cementing, stimulation, water and sand control chemical products. He has also been working on development of stimulation and water control treatment solution development process, treatment fluid placement, zone coverage, job design, and real-time treatment evaluation engineering methodologies. He holds BS and MS degrees in Physics from University of Rangoon, MS and PhD degrees in Chemical Engineering from the University of Florida.
