Candidate Well Selection for the Test of Degradable Biopolymer as Fracturing Fluid
MetadataShow full item record
Hydraulic fracturing is a well-established technology of generating highly conductive flow path inside the rock by injecting massive amount of fracturing fluid and proppant with sufficient pressure to break the formation apart. But as the concern for environment and health effects of hydraulic fracturing becomes intense, many efforts are made to replace the conventional fracturing fluid with more environment-friendly materials. The degradable biopolymer is one of the novel materials that is injected in the form of solid pellets containing proppant, degrades in the presence of water to form a viscous gel fluid, leaving no gel residue or harmful material. This work develops a methodology and computer program to determine the best candidate wells for the field test of degradable biopolymer as fracturing fluid. The unique properties of degradable biopolymer is captured in the selection of decision criteria such as bottomhole temperature and treatment volume as well as traditional hydraulic fracturing candidate well selection criteria such as formation permeability, productivity index.
