Abstract:
Methods and apparatus relate to systems and methods of recovering oil from a formation. In operation, a steam chamber develops as a result of steam injection into the formation and the recovery of fluids including the oil through a production well. An auxiliary well spaced in a lateral direction from the production well helps ensure development of the steam chamber as desired. The auxiliary well may enable heating of the formation through establishing an electric potential between the auxiliary well and the production well or by resistive heating of material forming the auxiliary well. Further, the auxiliary well may provide a flow path for solvent or gas injection to facilitate the recovery through the production well.
Abstract:
The present embodiment discloses a method for decreasing the time required for a start-up phase in a steam assisted gravity drainage production. The present method describes forming a steam assisted gravity drainage production well pair within a formation comprising an injection well and a production well, beginning a preheating stop by introducing heat between the injection well and the production well, beginning a steam squeeze stage by injection steam into the formation and beginning the steam assisted gravity drainage production.
Abstract:
A method for reducing thermal loss in a formation comprising two zone capable of production. The method first begins drilling a pair of wells, comprising a first well and a second well in a formation having two production zones, wherein one production zone is a thief zone such that the first well and the second well are in fluid communication with the thief zone. A sealing agent is injected into the thief zone via a first well and produced from the second well. Either the first well or the second well is then capped to form a capped well and a uncapped well. An amount of activating agent is injected into the uncapped well to form in-situ a thermally restrictive substance inside the thief zone.
Abstract:
An apparatus for securing a tool to a hangtag is provided. A method for securing the tool is also provided. In one embodiment, the invention pertains to a hangtag assembly that includes a fastening mechanism for securing a tool having a shank portion, such as a socket driver. The hangtag has a body portion, and a hanging mechanism connected to the body portion. The hangtag also has a tool fastening mechanism for securely attaching a tool to the hangtag. The tool fastening mechanism includes one or more pairs of through-openings, and one or more ties, wherein each tie is wove around the shank of the tool and through a respective pair of through-openings. In another embodiment, the invention pertains to a hangtag assembly that includes a fastening mechanism for securing a circular tool having a centrally located hub portion defining an opening therethrough. The hangtag has a body portion with a plurality of apertures therethrough and a tool fastening mechanism for securely attaching a tool to the hangtag. The tool fastening mechanism includes one or more pairs of openings therethrough. One or more ties, may be woven through the openings of the fastening mechanism, the opening of the tool, and the apertures of the body.
Abstract:
A hangtag is provided that is capable of hanging multiple tools. The hangtag has a body portion, a hanging mechanism connected to the body portion, and a tool supporting mechanism also connected to the body portion for supporting a tool. The body portion has a front surface and a back surface. On the back surface is disposed a hangtag attachment apparatus. The hangtag attachment apparatus comprises a bracket, and an elongated attachment bar configured to be selectively attached to and detached from the bracket. The attachment bar has a length that permits it to be connected to at least two and preferably more hangtags so that multiple hangtags may be selectively connected together. In this way, tools that would otherwise be sold individually can now be sold as a set.
Abstract:
A rotary device has a releasable tool holder. A spindle with two ends has one end adapted to secure to a rotary device and the other includes a bore to receive a tool. A mechanism to retain and release the tool from the spindle bore is coupled with the spindle adjacent the bore end. At least two unlike retention members to apply a force on the tool in the bore are adjacent the bore. A sleeve surrounds the bore end of the spindle as well as the at least two unlike retention members. The sleeve has a common surface to apply a force on the at least two unlike retention members such that when the sleeve is axially moved along the spindle, the force is varied with respect to the position of the surface on the retention member. This force maintains the tool in the bore or enables the tool to be removed from the bore. A biasing member maintains the sleeve in a retention position on the spindle.

Abstract:
An inflator mechanism has a valve adapted to secure with the device to be inflated. A compressor is fluidly coupled with the valve mechanism. The compressor mechanism generates fluid to inflate the device. The compressor mechanism includes a motor to drive a piston, a piston, a piston cylinder, an outlet coupled between the piston cylinder and the valve, and a housing. A biasing spring is positioned in the housing to exert a force on the cylinder. The biasing force maintains the cylinder in a first position when the fluid in the cylinder is at a low pressure. The cylinder moves in the housing against the force of the biasing spring to a second position when the fluid in the cylinder is at a high pressure. A displacement control valve is associated with the cylinder to control the fluid displacement of the compressor. Thus, at low pressure, fluid displacement is high and as pressure in the cylinder increases, the fluid displacement is reduced. A power source is coupled to drive the motor of the compressor.
