I want to work on aphron based drilling fluids during my PHD. Now I am reviewing the published literature but it would be great to have the opinion of an expert in this area.
ashron may act as a coat around the surface of pore wall during hydraulic fracturing, this may provide a good way for decreasing fracturing fluid run off, and you can search some related papers in the journal
Aphron fluid technology has enabled the redesign of wells in mature fields driving improved field economics into the picture. Aphron fluid technologies have mitigated the issues associated within these challenging mature environments, enabling the use of full density fluids, optimizing the working environment and eliminating the need for an intermediate string of pipe.
Aphron drilling Nano-fluid have three chief attributes that serve to minimize fluid invasion and damage of producing formations. First, the base fluid is very shear thinning and not very thixotropic, exhibiting an extraordinarily high low- shear-rate viscosity (LSRV) and flat gels; the unique viscosity profile is thought to reduce the flow rate of the fluid dramatically upon entering a loss zone. Second, various components in the mud interact to produce micro-gels that help to reduce spurt loss. Finally, very tough and flexible micro-bubbles, called “Aphrons,” create a soft seal within the permeable or fractured formation to reduce losses further. Aphron drilling fluids, which are highly shearthinning water-based fluids containing stabilized air-filled bubbles (Aphrons), have been applied successfully worldwide to drill depleted reservoirs and other high-permeability formations as well as fracture Granite formations.
Aphron is a micro bubble with a strong out film, which do not break either on compression or de-compression, unlike other bubble. It is being used a a drilling fluid in fractured formation and depleted reservoir. There is monopoly in the market because there are few manufacturer of the products used for aphron. I am also interested to use the product.
