A system and method for underground gasification. A system for underground gasification system may comprise a recovery system, a supply line, and a downhole ignition device operable to ignite an underground energy source. The downhole device may be connected to the supply line and the supply line may be connected to the recovery system. The system for underground gasification may further comprise an information handling system that may be operable to control the downhole device. A method for igniting an underground energy source may comprise disposing a downhole ignition device into an injection well, positioning the downhole ignition device within the underground energy source, activating the downhole ignition device, igniting the underground energy source, and recovering a gas from the underground energy source.

Embodiments of the hybrid tool string include coiled tubing and jointed tubing, as well as a means typically located at the connection of the coiled and jointed tubing for sealing the fluid flowpath through the bore of the hybrid tool string. Embodiments of the hybrid tool string may use a pressure-activated valve tool attached in series between the coiled tubing and the jointed tubing, which allows for sealing of the bore by application of pressure. Embodiments of the pressure-activated valve tool may use a flapper in conjunction with a sleeve to seal the bore. The novel hybrid tool string may be used to service a well.

A wellbore servicing apparatus, comprising a first mandrel movable longitudinally along a central axis and rotatable about the central axis, an orienting member configured to selectively interfere with movement of the first mandrel along the central axis, and a second mandrel connected to the first mandrel and configured to rotate about the central axis when the first mandrel rotates about the central axis. A method of orienting a wellbore servicing tool, comprising connecting an orienting tool to the wellbore servicing tool, identifying a predetermined direction, increasing a pressure within the orienting tool, rotating a portion of the orienting tool in response to the increase in pressure within the orienting tool, and rotating the wellbore servicing tool in response to the rotating of the portion of the orienting tool.

Apparatuses and methods for generating fluid pressure pulses are disclosed. An example apparatus may include a chamber that can collect fluid and an upstream ported disc coupled to a downstream end of the chamber. The upstream ported disc may rotate about a central axis. The upstream ported disc includes an upstream eccentric port that rotates about the central axis as the upstream ported disc rotates. The example apparatus may include a downstream ported disc coupled to a downstream end of the upstream ported disc such that the downstream ported disc remains substantially rotationally fixed relative to the upstream ported disc. The downstream ported disc includes a downstream eccentric port that may align with the upstream eccentric port to form a passageway for fluid to exit from the chamber to outside of the apparatus, at some time in a rotation cycle of the upstream ported disc.

A run-in and retrieval device for a downhole tool comprises a first set of lugs disposed on a first component of the device connected to a tool string, and a second set of lugs disposed on a second component of the device connected to the downhole tool, wherein the first set of lugs interact with the second set of lugs in a connected position. A method for running at least one downhole tool into a well bore comprises forming a releasable connection between an overshot connected to a tool string and a mandrel connected to the at least one downhole tool, running the at least one downhole tool into the well bore via the tool string, manipulating the at least one downhole tool in the well bore; and, rotating the overshot less than 360 degrees with respect to the mandrel to release the connection therebetween.

A device and a method are provided for the hydraulic fracturing of multiple zones in a well bore. A stinger carries a plurality of packers into a well bore. Each packer is separably connected to each adjacent packer. As each packer is sequentially secured in the well bore, the stinger is withdrawn from the secured packer and the process is repeated as the remaining packers are sequentially secured and separated.

Multiple zones frac tool

The present invention provides a tool and methods of placing a treatment fluid in a subterranean formation penetrated by a well bore by way of selected perforations extending from casing cemented in the well bore into the formation. The fluid placement tool includes a fluid flow passageway extending therethrough, at least one resilient self expandable cup type packer attached thereto and a valve disposed in the fluid flow passageway which closes the passageway when a closing plug is dropped into the tool. The placement tool is capable of releasing the cup type packer whereby it provides a seal between the tool and the casing when a first predetermined fluid pressure is applied to the tool after a closing plug is dropped therein and opening the fluid flow passageway whereby the treatment fluid is discharged from the tool below the packer when the fluid pressure is increased to a second predetermined fluid pressure. Methods of using the tool are also provided.
