Described herein are methods and techniques for deep reservoir stimulation of a hydrocarbon-containing subsurface formation. The methods may comprise introducing or injecting a formation-dissolving fluid, such as a wet acid-forming gas, into the subsurface formation; allowing the formation-dissolving fluid, such as the wet acid-forming gas, to react with the subsurface formation for a period of time; and producing hydrocarbons from the subsurface formation.

Methods for deep reservoir stimulation using acid-forming fluids

A tool assembly is provided that includes an actuatable tool such as a valve or a setting tool. And includes a location device that senses the location of the tool assembly within a tubular body based on a physical signature. The tool assembly also includes an on-board controller configured to send an activation signal to the actuatable tool when the location device has recognized a selected location of the tool based on the physical signature. The actuatable tool, the location device, and the on-board controller are together dimensioned and arranged to be deployed in the wellbore as an autonomous unit.

Autonomous downhole conveyance system

Systems and methods for stimulating a plurality of zones of a subterranean formation to increase production of reservoir fluids therefrom. The subterranean formation contains a well that includes a liner that defines a liner conduit, and the systems and methods include stimulating the plurality of zones with a stimulation assembly that is present within the liner conduit without requiring removal of the stimulation assembly from the liner conduit. The stimulation assembly includes a perforation device, which is configured to selectively form one or more perforations in a plurality of portions of the liner, and a resettable sealing device, which is configured to fluidly isolate the plurality of portions of the liner from a plurality of respective downhole portions of the liner. The fluid isolation provides for selective introduction of a stimulant fluid to a selected zone of the subterranean formation that is associated with a corresponding portion of the liner.

Systems and methods for stimulating a plurality of zones of a subterranean formation

A method for drilling and completing a gravel packed well is disclosed. The method comprises drilling a wellbore with a drilling fluid, conditioning the drilling fluid, running the gravel packing assembly tools to depth in the wellbore with the conditioned drilling-fluid, and gravel packing a wellbore interval with a completion-fluid. The completion fluid may be the same as the drilling-fluid. This method may be combined with alternate-path sand screen technology to ensure proper distribution of the gravel pack.
