Claims15
A method to provide a fractured subterranean formation comprising:
- providing a wellbore in the subterranean formation;
- and
- providing fractures in the subterranean formation through a primary perforation using a mortar slurry tuned to reach a threshold so as to allow only desirable diversion into a secondary perforation.
A method to provide a fractured subterranean formation comprising:
- providing a wellbore in the subterranean formation;
- and
- providing fractures in the subterranean formation through a primary perforation using a mortar slurry designed to self-divert at low flow rates, thereby lowering screenout risk.
A method to provide a fractured subterranean formation comprising:
- providing a wellbore in the subterranean formation;
- and
- providing fractures in the subterranean formation using a fracturing fluid comprising a lightening agent;
- thereby creating a bias toward upward growth of the fractures.
A method to provide a fractured subterranean formation comprising:
- providing a wellbore in the subterranean formation;
- providing fractures in the subterranean formation using a first fracturing fluid having a first density and a second fracturing fluid having a second density.
A method of interpreting a propped area comprising:
- providing a wellbore in a subterranean formation;
- providing fractures in the subterranean formation by pumping a fracturing fluid designed to remain within the fractures;
- and
- based on the volume of fracturing fluid pumped, estimating the propped area.
A method of mitigating production of fines, comprising:
- providing a wellbore in a subterranean formation;
- providing fractures in the subterranean formation using a fracturing fluid designed to mitigate production of fines.
