... to any stimulation considerations in naturally fractured reservoirs. Another potential cause of unexpected well performance might be the creation of multiple fractures. Studies have suggested that fracture length is limited by multiple fractures and that larger treatments do not result in significant...

... on either the microscopic or megascopic scales. Computer-capacity limitations make it difficult to include enough fractures to model a region even the size of one reservoir grid block. Clustering of fractures into swarms appears to be the key to fracture interconnectivity. fracture length upstream...

... events. Fracture lengths and heights from the passive seismic events varied along with the directions. The length of the wing to the southwest showed seismic events over 1200 feet from the well, while the east wing events only reached about 700 feet. The different wings also showed a large variation...

... attributed to complex fracturing. 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. effective fracture length stress profile drillstem/well testing...

... 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...

..., with the current stimulation techniques used in the Spraberry Trend, hydraulic fracture lengths approach drainage radii where x e /x f = 1, 2, 3 or 4, making the Fetkovich type-curves unapplicable for this study. Another possible type-curve available for consideration in this study is the one developed...
