US Patent:

8403051, Mar 26, 2013

Filed:

Oct 13, 2010

Appl. No.:

12/903802

Inventors:

Tianping Huang - Spring TX, US
James B. Crews - Willis TX, US
John R. Willingham - Cypress TX, US
Richard A. Mitchell - Houston TX, US
Kushal Seth - Houston TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 43/16

US Classification:

166307

Abstract:

Emulsified acids have been used to increase production rates of oil and gas in carbonate reservoirs through acid fracturing and matrix acidizing operations. An emulsifier is used to emulsify the aqueous acid with an oil, usually diesel. Very small particles, such as colloidal clay particles and/or nanoparticles increase the stability of the emulsified acids over an elevated temperature range.

US Patent:

20110005752, Jan 13, 2011

Filed:

Jul 13, 2010

Appl. No.:

12/835023

Inventors:

Tianping Huang - Spring TX, US
Richard A. Mitchell - Houston TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 43/34
E21B 43/02

US Classification:

166276, 166319, 166279

Abstract:

Water production produced from a subterranean formation is inhibited or controlled by consolidated water sensitive porous medium (WSPM) packed within the flow path of the wellbore device container. The WSPM includes solid particles having a water hydrolyzable polymer at least partially coating the particles. The WSPM is packed under pressure within the flow path of the wellbore device container to consolidate it. The WSPM increases resistance to flow as water content increases in the fluid flowing through the flow path and decreases resistance to flow as water content decreases in the fluid flowing through the flow path.

US Patent:

Filed:

Aug 17, 1981

Appl. No.:

6/293155

Inventors:

Richard L. Mitchell - Rolling Hills Estates CA

Assignee:

Mark Resources, Inc. - Santa Monica CA

International Classification:

G01S 740

US Classification:

343 177

Abstract:

Apparatus and methods are disclosed in which a radar target can be electronically disguised to appear like another target. The technique is based on the generation of a desired synthetic target signature that is superimposed on the normal radar echo for the simulation platform. The simulation system consists of multiple antennas with tapped delay lines and signal modulators to provide the means of generating the desired target signal that is extended in angle and range. It is possible to utilize very realistic models of the desired target; the necessary information can be collected on a high-resolution measurement range. The general technique works against any pulsed radar in a monostatic geometry. A modified technique for operation against continued wave and bistatic radars is also discussed. The applications of the technique include the testing of missileborne guidance radars against cooperative targets and electronic countermeasures (ECM) applied to a target vehicle to deceive the radar.
