US Patent:

20040251033, Dec 16, 2004

Filed:

Jun 11, 2003

Appl. No.:

10/459387

Inventors:

John Cameron - The Woodlands TX, US
Calum Whitelaw - Aberdeenshire, GB

International Classification:

E21B023/00

US Classification:

166/382000, 166/206000, 166/207000

Abstract:

An improved method for completing wells, such as hydrocarbon wells, is provided. In one aspect, methods are provided for deploying an expandable tubular, such as an expandable sand screen, in a hydrocarbon well. According to methods of the present invention, a sand screen is lowered into a wellbore. Thereafter, cement is injected into the wellbore so as to place a column of cement in the annular region between the tubular and the surrounding formation. The cement is then treated so as to imbue greater permeability and/or porosity characteristics. The cement serves to reinforce the sand screen, providing it with both improved physical strength and improved sand filtering ability. At the same time, the sand screen serves to reinforce and strengthen the cement sheath placed in the wellbore.

International Classification:

H02N 1300

US Classification:

361234

Abstract:

An electrostatic chuck 20 of the present invention is capable of maintaining substantially uniform temperatures across a substrate 30. The chuck 20 comprises an electrostatic member 35 that includes (i) an insulator 45 covering an electrode 40, (ii) a substantially planar and conformal contact surface 50 capable of conforming to a substrate 30, and (iii) conduits 105 terminating at the contact surface 50 for providing heat transfer fluid to the contact surface 50. Application of a voltage to the electrode 40 of the electrostatic member 35 electrostatically holds the substrate 30 on the conformal contact surface 50 to define an outer periphery 110 having (1) leaking portions 115 where heat transfer fluid leaks out, and (2) sealed portions 130 where heat transfer fluid substantially does not leak out. A fluid flow regulator 135 is provided for flowing heat transfer fluid at different flow rates through the conduits 105 in the electrostatic member 35 to provide (i) first flow rates of heat transfer fluid through the conduits 105 adjacent to the sealed portions 130 of the outer periphery 110 of the electrostatic member 35, and (ii) second flow rates of heat transfer fluid through the conduits 105 adjacent to the leaking portions 115, the second flow rates being higher than the first flow rates, to maintain substantially uniform temperatures across the substrate 30 held on the chuck 20.

John Alasdair Cameron - Houston TX, US

International Classification:

E21B 43/08

Abstract:

A sand control screen assembly having a filter medium that provides a controlled offset between a shroud and the filter medium, and/or between a base pipe and the filter medium. The sand control screen assembly may also include a drainage layer positioned about the base pipe. The sand control screen assembly is utilized for preventing the flow of particulate material of a predetermined size therethrough and allowing the flow of production fluids therethrough.

Abstract:

Systems and methods for warning of proximity in a worksite are disclosed. A second transceiver is detected at a first transceiver, wherein the first transceiver is a mobile wearable device, and wherein the first transceiver and the second transceiver are located at a worksite. An ad-hoc network is established, at the first transceiver, between the first transceiver and the second transceiver. A distance is calculated, at the first transceiver, in three dimensions between the first transceiver and the second transceiver based on the detecting the second transceiver. A first safety envelope is defined, at the first transceiver, about the first transceiver and a second safety envelope about the second transceiver. An alarm is issued, at the first transceiver, when the first safety envelope comes in contact with the second safety envelope.
