Title: High-pressure coiled-tubing technology solves resin-sand-control problems

Abstract

Operators of high-pressure offshore gas wells (> 5,000 psi) have had few options for controlling sand production. Sand-control (SC) processes can be economically prohibitive when they involve extensive mobilization, demobilization, and rig-up cost of the conventional offshore rig or hydraulic workover unit. Bullheading SC chemicals from the surface can damage the formation and prohibit production. Coiled-tubing (CT) technology now allows an offshore operator to remove extensive cement residue effectively from the wellbore and place chemical SC treatments in a high-pressure-gas environment. An example from the Gulf of Mexico illustrates the technology.
