Abstract
A system for fracturing a formation includes a tubular positionable within a formation borehole having at least one port therethrough configured to provide fluidic communication from inside the tubular to the formation borehole. The system also includes a seal sealably attachable to both the tubular and walls of the formation borehole, a seat in operable communication with the tubular and a member in operable communication with the seat such that movement of the seat relative to the tubular causes the member to engage the walls and provide stress thereto.
Claims24
A system for fracturing a formation, comprising:
- a tubular positionable within a formation borehole having at least one port therethrough configured to provide fluidic communication from inside the tubular to the formation borehole;
- a seal sealably attachable to both the tubular and walls of the formation borehole;
- a seat in operable communication with the tubular;
- and
- a member in operable communication with the seat such that movement of the seat relative to the tubular causes the member to engage the walls and provide stress thereto.
A method of fracturing a formation, comprising:
- sealingly attaching a tubular to walls of a borehole in the formation;
- pressuring up the tubular;
- deforming a member in operable communication with the tubular into engagement with the walls;
- urging the member longitudinally away from the sealing attachment;
- stressing the walls with the urging;
- and
- pressuring up the formation.
A method of increasing depth of fracturing a formation, comprising
- applying longitudinal loads to walls of the formation;
- and
- pressuring up against the formation.
