The Use of Chemical-in-Gas Dispersions for Well Productivity and Recovery Enhancement
Recorded On: 12/08/2020
Conventional liquid-based stimulation treatments have shown several limitations such as low treatment penetrations and short durability, among others. To overcome these shortcomings, a novel well productivity and recovery enhancement technology has been proposed where the carrying fluid is gas instead of liquid.
Several successful field applications for condensate banking removal, asphaltenes dissolution, and gas injection conformance, demonstrate the advantages of the technique with proven benefits. The use of chemical-in-gas dispersions enhances the treatment’s distribution and increases the stimulated rock volume due to better conformance and gas diffusion effects. It maximizes durability through tunable adsorption, improves the well’s flowback performance and reduces the risk of generating liquid-induced damage.
This webinar presents an overview of the use and potential of chemical-in-gas stable dispersions for well stimulation and enhanced oil recovery with different field case studies, and opens discussion to future potential applications.
