Starch-Lubricant Compositions for Improved Lubricity and Fluid Loss in Water-Based Drilling Muds

Abstract: Development of water-based mud systems that approach the performance of oil-based muds is an ongoing effort. Starch-lubricant compositions were developed as environmentally safe, non-toxic, stable dispersions in water-based drilling muds. Starch-lubricant compositions were prepared by jet cooking mixtures of water, starch, and lubricant to produce aqueous starch dispersions containing suspended lubricant droplets 1–10 microns in diameter. These droplets do not separate or coalesce. The dispersions were drum dr… Show more

“…Non-food applications demonstrating the efficacy of oil delivery in aqueous starch-based media included biodegradable polyurethane foams (Cunningham et al ., 1997 ), lubricants for water-based oil drilling muds (Fanta et al ., 2002a ;Sifferman et al ., 2003 ) and lubricants for metal working (Biresaw, 2004 ;Biresaw and Erhan, 2002 ;Biresaw et al ., 2007 ;Kenar et al ., 2009 ). The jet-cooked starch-oil technology was also used to deliver a soybean oil-based UV absorbing agent to provide UV protection in cosmetic and agricultural applications, and was shown to increase the efficiency of UV absorption (Compton et al ., 2007 ).…”

“…[1][2][3] Due to the natural lubricating properties of the base oil used to formulate invert emulsion drilling fluids (IEDFs), there are few lubricants developed for IEDFs so far. [4,5] However, today's operators have to drill deeper and further to seek out new sources of supply. Such operations regularly challenge operators with issues of high torque and drag, often leading to increased wear in rig equipment, low drilling rate and complex accidents (such as pipe sticking).…”
