Guar and its derivatives are the most commonly used gelling agents in fracturing treatments. In the last few years, enormous price swings and supply shortages of guar have posed major challenges for service companies and operators. In addition, the f

It is challenging to remove filter cake uniformly and thoroughly from the production interval in horizontal and multi-lateral wells with heterogeneous formation characteristics. The inability to obtain complete filter cake removal is a common occurre

Chemically impregnated substrates have been successfully used for several years in fracture treatments to achieve long-term inhibition of downhole scale and other precipitates. These solid chemical treatments are gaining wider interest in non-fractur

Most oil and gas producing formations contain clay minerals that were deposited during the sedimentation process, formed during the interaction of heat, pressure, and time on the naturally present minerals in the formation, or precipitated from fluid

With increased utilization of ultra-lightweight proppants, several operational challenges have been encountered. Blending and measurement challenges arise from the relative closeness of the specific gravity of ultra-lightweight proppants to the base

During the drilling process with OB (oil-based) and SB (synthetic-based) mud systems, mud solids form internal and external filter cake along the wellbore through a filtration process (due to filtrate leakoff to the formation). After drilling is comp

Polymers used in completion and workover operations can consist of cellulose, cellulose derivatives, guar and guar derivatives. Normally these polymers are used in completion and workover fluids consisting of potassium, sodium and ammonium chloride.

This paper describes the lab testing procedures and results for testing formation core material and used drill-in fluid samples to optimize wellbore clean-up procedures. In addition, a three well case history reviewing completion damage of horizontal

Temporary well isolation projects have been successfully performed using a non-formation damaging polymer plug and coiled tubing. Previously used conventional kill muds can cause severe formation damage, reducing productivity once the well is put bac

Many horizontal wells are drilled using the clean "drill-in fluids" introduced in recent years. The drill-in fluids are typically comprised of either starch or cellulose polymers, xanthan polymer, and sized carbonate or salt particulates. They were i
