... restrictions, and the development of multiple fractures in a single, bounded layer were evaluated as possible causes for the high initiation pressures. Results from this work showed the multiple fractures model providing the best match for the two wells. Fracture length varied from approximately 1150 ft to 750...

The inability to significantly improve "effective" fracture length with increasing fluid & proppant volumes resulted in reduced treatment sizes (and treatment costs) and improved well economics.

... ABSTRACT Achieving effective fracture lengths in carbonate formations by fracture acidizing has long been a recognized industry challenge. Severe fluid loss is generally considered a major factor limiting the effectiveness of acid fracturing treatments. A unique new acid fracturing fluid has...
