Determining Horizontal And Vertical Permeabilities By Analyzing Two Pretests In A Horizontal Well
US Patent:
7231818, Jun 19, 2007
Filed:
Dec 16, 2004
Appl. No.:
11/014422
Inventors:
James J. Sheng - Katy TX, US
Daniel T. Georgi - Houston TX, US
Daniel T. Georgi - Houston TX, US
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
E21B 47/00
US Classification:
7315205
Abstract:
In one method, the permeabilities are obtained by correcting the geometric factor derived from combining the FRA analysis and buildup analysis. In a second method, the permeabilities are obtained by combining the spherical permeability estimated from buildup analysis and the geometric skin factor obtained from history matching the probe-pressure data. In another method, horizontal and vertical permeabilities are determined by analysis of pressure drawdown made with a single probe of circular aperture in a substantially horizontal borehole at two different walls of the borehole.

Determination Of An Actual Optimum Salinity And An Actual Optimum Type Of Microemulsion For Surfactant/Polymer Flooding
US Patent:
2009019, Aug 6, 2009
Filed:
Jan 31, 2008
Appl. No.:
12/023499
Inventors:
James J. Sheng - Katy TX, US
Assignee:
Total E&P USA, Inc. - Houston TX
International Classification:
E21B 43/22
US Classification:
1662523
Abstract:
Systems and methods for the determination of an optimum salinity type and an optimum salinity of a surfactant microemulsion system are shown. Optimum salinity type and optimum salinity in surfactant/polymer flooding is determined, according to embodiments, by core-flood experiments so that a variety of multiphase flow parameters such as relative permeability and phase trapping that affects oil recovery factor, influences the determination of the optimum salinity type and optimum salinity. The optimum salinity determined from this approach preferably corresponds to the highest oil recovery factor.
Optimum Salinity Profile In Surfactant/Polymer Flooding
US Patent:
2009019, Aug 6, 2009
Filed:
Jan 31, 2008
Appl. No.:
12/023738
Inventors:
James J. Sheng - Katy TX, US
Assignee:
Total E&P USA, Inc. - Houston TX
International Classification:
E21B 43/22
US Classification:
1662701
Abstract:
An optimum salinity profile in surfactant/polymer flooding from formation water to post-flush drive that leads to the highest oil recovery factor is shown. The optimum salinity determined from core-flooding experiments is preferably used in the surfactant slug. The surfactant slug is protected from deterioration by the injection of cushion slugs immediately before and after the injection of the surfactant slug in a reservoir wherein the cushion slugs have the same salinity or about the same salinity as the surfactant slug. According to embodiments, a salinity lower than the lowest salinity of Type III, C, is used in the post-flush drive, while formation water could be of any salinity.
