Appl. No.:

11/187204

Inventors:

Edward J. O'Malley - Houston TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 23/06
E21B 33/12

US Classification:

166187, 166387, 166189, 166191, 166195, 166100

Abstract:

A packer device and methods of use for a packer within uncased wellbore to form a complete fluid seal. The packer device includes a central mandrel body that retains a plurality of nested, telescopic expanding elements that are moveable outwardly from the mandrel body. The mandrel body and expanding elements are surrounded by a load-distributing structure as well as a sealing element, which is typically comprised of elastomer. The packer device is hydraulically actuated to urge the expansion members radially outwardly against the load-distributing structure and the sealing element. Because there are a number of discrete expansion elements, the packer device is better able to create a fluid seal within an uncased borehole with surface irregularities.

US Classification:

166179, 166387, 166300, 277331, 277934

Abstract:

A sealing element that swells on exposure to well fluids present or added to the wellbore is assembled to the mandrel in a manner to induce circumferential stresses proximately to the inside diameter of the element so as to resist the tendency of the inside diameter of the element to grow during the swelling process. A vacuum and a pressure method are described. Leak paths between the mandrel and the sealing element are minimized or eliminated as a result.

International Classification:

E21B 23/00

US Classification:

166382, 166208

Abstract:

A liner hanger has a housing with a pocket disposed on an inner wall surface and a slip slidingly engaged within the pocket. The liner hanger housing is secured in the string of casing. A setting mechanism connected to the slips is also located in the pocket. An actuator is mounted on the liner. As the liner is moved through the casing coupler, the actuator actuates the setting mechanism, causing the slips to move axially downward. As the setting mechanism moves downward, the slips move radially inward and grip the liner.

Abstract:

A liner hanger has a housing with a pocket disposed on an inner wall surface and a slip slidingly engaged within the pocket. The liner hanger housing is secured in the string of casing. Both a setting mechanism and a liner engagement member are connected to the slips and are also located in the pocket. A releasable latching mechanism maintains the slips in the run-in position until the releasable latching mechanism is actuated. As the liner is moved through the casing coupler, the liner engagement member engages the liner through frictional force to cause the setting mechanism to move with the liner so that the latching mechanism can be disengaged and the slips can move axially downward. As the setting mechanism moves downward, the slips move radially inward and grip the liner.

International Classification:

E21B 33/12

US Classification:

166179

Abstract:

A swelling element rate regulation technique and product features an outer coating on a core of an element. The core is reactive to hydrocarbons or water depending on how it is configured. The surrounding coating is preferably formed of fine ground particles of a non-swelling polymer mixed in a solvent such as methyl-ethyl-ketone that is applied in a thin layer to the core exterior. This uncured outer layer is then contacted by a patterned surface. The patterned surface is pressed firmly against the uncured polymer/solvent mixture and transfers an inverse of the pattern to the surface of the coating. As pressure is applied, heat may also be applied to cure the coating. The resulting pattern is designed such that openings in the coating are created that regulate infiltration of water or other fluids through it and, as a result, the rate of swelling in the wellbore. Swell rate in governed in part by the ratio of the exposed area of the swelling compound to the total volume of the swelling compound. The smaller this ratio, the slower the rate of swell.

International Classification:

E21B 43/25

US Classification:

166 651, 1661771, 166249, 166 685

Abstract:

A spark-gap tool includes a plurality of electrodes, a mandrel, transductive element(s), and a force transmission configuration. Upon relative movement between components a physical distortion of one or more transductive elements occurs, whereby an electrical potential is generated. A method for powering the spark-gap tool is by physically distorting one or more transductive elements by moving components axially and/or rotationally. A method for treating a borehole is by physically distorting one or more transductive elements thereby creating sufficient voltage potential to cause an arc of selected magnitude across a spark-gap in the tool. A downhole power generation arrangement includes a first member and a second member that are movable and a piezoelectric element on one of the first member and the second member and in force transmissive communication with the other of the first member and the second member.

Abstract:

Gas hydrates, particularly natural gas hydrates e. g. methane hydrates, may be formed and controlled within conduits and vessels by imparting energy to gas and water, for instance using agitation or vibration. The systems and methods allow for improved flow characteristics for fluids containing the gases, e. g. hydrocarbon fluids being transported, and for improved overall efficiencies. The gas and water within a gas flow path may be perturbed or agitated to initiate formation of relatively small hydrate particles. The hydrate particles continue to form as long as energy is imparted and water and hydrate guest molecules are available. High amplitude agitation of the gas and water will repeatedly break up agglomerated hydrate particles that form and encourage the formation of more and smaller particles. As more hydrate forms in this manner, less and less free water may be available proximate the gas and water contact.
