Abstract

A method of creating a well bore includes providing a bore liner in a section of a well bore extending through a formation and providing the liner with at least one frac sleeve. A frac bottom hole assembly (BHA) is mounted on a string of jointed pipe, and the BHA is run into the well bore through a blowout preventer (BOP). The BHA is located adjacent the sleeve. A seal on the BOP is activated to engage the jointed pipe. The BHA is activated to engage the frac sleeve. The BHA is then translated to open a port in the frac sleeve. A surface pump then delivers fracturing fluid through the port into the formation surrounding the liner. After stopping the flow of fluid, the BHA is translated to close the port in the frac sleeve.
