Paper Number: SPE-36603-MS
... problems associated with drilling, completing, and working over wells. Introduction Hydraulic fracturing is one of major methods to increase reservoir production. The success or failure of a fracture treatment heavily depends on the fracturing fluids and additives used in the treatment. Choosing...

... range from 0.5 lbm/1,000 gal to 20 lbm/1,000 gal. There are other additives contained within water fracs as well such as polymer friction reducers with surfactants, biocides, and clay stabilizers ( Grieser et al., 2003 ). Although this fracturing fluid is simple in its composition, it still yields very...

... An evaluation of acid additives and retarded acid systems indicates that the stimulation resulting from acid fracturing can be increased when effective fluid loss additives used in HC1, or when the acid viscosity is increased significantly. Acid emulsions were found to have a low fluid loss rate...
