Uniform InFlow Completion System Extends Economic Field Life: A Field Case Study and Technology Overview

Abstract

Abstract Horizontal wells on a global basis continue to serve as a primary well type for improving recovery efficiency, increasing reservoir drainage area, delaying water and gas coning and increasing production rate. However, in longer, highly deviated and horizontal wells, non-uniform flow profiles can result in premature water or gas breakthrough, screen plugging and erosion, which can shorten well life and decrease well profitability. This paper describes historical and new applications of a proven production technology system that optimizes production, delays water and gas coning, minimizes annular flow to prevent erosion and ensures uniform inflow along the lateral at the cost of a minute pressure drop in high-rate horizontal wells. Case histories will be presented from the Norwegian Sector of the North Sea and offshore Saudi Arabia, where this production technology, combined with sand-control technology, has resulted in significant savings for the operator and improved production in horizontal offshore oil wells.
