Systems, methods, and instructions encoded in a computer-readable medium can perform operations related to simulating injection treatments applied to a subterranean formation from multiple well bores in the subterranean formation. A subterranean formation model representing rock blocks of a subterranean formation is received. Information on multiple injection treatments for multiple well bores in the subterranean formation is received. The subterranean formation model and the information on the injection treatments is used to predict a response of each of the rock blocks to forces acting on the rock block during the injection treatments. The injection treatments may include, for example, multiple fracture treatments for simultaneous application to the subterranean formation. In some implementations, injection treatments may be designed for a multiple-well bore system based on the predicted response of the rock blocks.

Simulating injection treatments from multiple wells

A formation isolation valve for underbalanced drilling applications. A system for operating a formation isolation valve includes the valve interconnected in a casing string. An assembly displaces through the casing string, thereby causing the valve to open prior to the assembly reaching the valve. An operating system includes a well tool with an actuator positioned downhole. A device for causing the actuator to operate the well tool is also positioned downhole remote from the actuator. A method of operating a well tool includes the steps of: positioning the well tool in a well, the well tool including an actuator; positioning a power source for the actuator in the well; and at a downhole position remote from the actuator, causing the actuator to operate the well tool.
