An alternative system to conventional HEC (hydroxyethylcellulose) and particulate fluid loss materials has been developed for fluid loss control in high permeability Gulf of Mexico Flexure trend completions. In offshore operations, the problem of controlling fluid loss to the formation is critical in achieving successful gravel pack completions. The problem is magnified in this environment because of the use of expensive high density brine, lost rig time, and increased standards for well control and safety. A newly developed fluid loss system which consists of a cross linkable, derivatized HEC incorporating a branched ·functional group oil an HEC backbone has been evolving in the industry.The functional group provides a nonionic reaction site which allows the polymer to be crosslinked at a low pH, and broken in a controlled manner using a newly developed breaker.

“…This study discusses in detail the frictional pressure performance along with rheological properties of the three commonly used carrier fluids (Underdown et al 1989;Campbell et al 2002;Houchin et al 1988): VES, xanthan, and HEC. Field-scale yard tests were performed at ambient and elevated temperatures to acquire frictional-pressure data in various conduits including circular pipe (wash pipe), eccentric annuli (wash pipe/screen-base pipe), and rectangular tubes (shunt tubes).…”

Gravel packing is increasingly used in long horizontal wells and challenging environments. Key to executing the gravel-pack job successfully is selecting an appropriate gravel-carrier fluid. Frictional pressure loss exhibited by gravel-packing fluids is an important consideration in their selection. This paper discusses the friction pressure performance of commonly used gravel-packing fluids in the industry today, which include the viscoelastic surfactant (VES) types of fluids, xanthan, and hydroxyethyl cellulose (HEC).In wells with a long horizontal section or narrow margin between pore pressure and fracture gradients, the frictional pressure loss exhibited by these fluids in the wash pipe and washpipe/base-pipe annulus governs whether these wells can be gravel packed without fracturing the formation. In gravel packs with alternative-path configuration (shunts), the frictional pressure loss through the shunts controls the maximum length that can be gravel packed.This paper discusses in detail the fluid friction pressure performance while pumping these fluids through various conduits including circular pipe, eccentric annuli, and rectangular tubes (shunts). These data were generated in field-scale yard tests under controlled conditions, for both ambient and elevated temperatures. The paper also discusses the rheological properties of these fluids at ambient and elevated temperatures. The effect of factors such as surfactant/ polymer concentration, addition of gravel, and temperature on the frictional pressure loss of these fluids is presented, which will help in fluid selection/optimization under different scenarios.
