Improved oil production using economical biopolymer-surfactant blends for profile modification and mobility control. Final report, November 1998

Description

In the past, starch hydrocolloids have not been effective alternates to partially hydrolyzed polyacrylamides, copolymers, and xanthan gum polymers as water shutoff agents in fractures and in matrix flow configurations. Poor injectivity and questionable stability have usually prevented their use in profile control applications. However, in recent years, the demands of the oil and gas drilling industry have led to the development of new drilling, drill-in, and completion fluids with improved functionality. New types of modified starches have contributed to these new drill in fluid (DIF) products. It was felt that the properties of the new products would lend themselves ... continued below

Description

In the past, starch hydrocolloids have not been effective alternates to partially hydrolyzed polyacrylamides, copolymers, and xanthan gum polymers as water shutoff agents in fractures and in matrix flow configurations. Poor injectivity and questionable stability have usually prevented their use in profile control applications. However, in recent years, the demands of the oil and gas drilling industry have led to the development of new drilling, drill-in, and completion fluids with improved functionality. New types of modified starches have contributed to these new drill in fluid (DIF) products. It was felt that the properties of the new products would lend themselves to applications in improved recovery. The objective of this project has been to evaluate the use of agricultural starch biopolymers for gelled and polymer applications in oil recovery processes. The authors believe that there is great potential for finding new functional starch products because of their chemical and structural flexibility, low cost, and wide availability. The goals of this project have been, therefore, to systematically investigate how the physical properties and chemical composition of relatively inexpensive agricultural starch products will influence their use as effective selective permeability control agents or as gels for water shut-off.
