Abstract
There is provided a method of testing a subterranean formation for fracture condition, including the steps of creating a side bore into the wall of a well traversing the formation, sealing the wall around the side bore to provide a pressure seal between the side bore and the well, pressurizing the side bore beyond a pressure inducing formation fracture while maintaining the seal and monitoring the pressure to identify the fracture condition.
Claims11
A method of testing a subterranean formation for a fracture condition, comprising:
- creating a side bore into a wall of a well traversing said formation;
- sealing said wall around the side bore to provide a pressure seal between said side bore and said well;
- pressurizing the side bore beyond a pressure inducing formation fracture while maintaining said seal;
- and
- monitoring the pressure to identify said fracture condition.
