A method of fracturing a rock formation includes cementing a production pipe to a wellbore within the rock formation, wherein a seat is attached to an inner surface of the production pipe. The method further includes forming access ports along a first section of the wellbore that fluidly connect the production pipe to the wellbore, delivering treatment fluid from the production pipe to the wellbore through the access ports, flowing formation fluid from the rock formation to the production pipe through the access ports, and closing an opening in the seat to isolate the first section of the wellbore from a second section of the wellbore located above the first section.

Multi-stage fracturing techniques in oil and gas

A method of sealing one or more leak paths includes positioning an isolation plug in a production tubing. The production tubing is disposed within a wellbore casing assembly, each extending into a subsurface. The wellbore casing assembly includes a production casing. A tubing/casing annulus is disposed between the production casing and the production tubing. The one or more leak paths are fluidly coupled to the production tubing and the tubing/casing annulus and the isolation plug is positioned at a depth location below the one or more leak paths. The method also includes perforating the production tubing at a depth location above the isolation plug to form one or more sealant injection holes fluidly coupling the production tubing and the tubing/casing annulus and directing a sealant into the production tubing such that the sealant enters the tubing/casing annulus through the one or more sealant injection holes.
