Experimental and Theoretical Simulation of Gravel Pack Displacement in Extended Horizontal Offshore Wells

摘要

This article presents the development of a computational tool to guide horizontal gravel pack design for long horizontal offshore wells. Mechanistic model formulation, experimentation at a large scale flow loop and software development are detailed. The computer simulation results are then compared with field data collected in Campos Basin operations, offshore Brazil. A discussion on design alternatives for long horizontal well at low frac gradient formations is presented. This discussion includes a sensibility analysis on screen eccentricity, open and closed BOP configurations and alpha vs alpha plus beta wave displacement options.
