Bentley J. Palmer - Missouri City TX
Dean M. Willberg - Sugar Land TX
Roger J. Card - Paris, FR
J. Ernest Brown - Katy TX
Philip F. Sullivan - Bellaire TX
Assignee:
Schlumberger Technology Corporation - Sugar Land TX

Compositions Containing Aqueous Viscosifying Surfactants And Methods For Applying Such Compositions In Subterranean Formations

US Patent:
6435277, Aug 20, 2002
Filed:
Feb 23, 1999
Appl. No.:
09/256980
Inventors:
Qi Qu - Stafford TX
Erik B. Nelson - Houston TX
Dean M. Willberg - Sugar Land TX
Mathew M. Samuel - Katy TX
Frank F. Chang - Sugar Land TX
Roger J. Card - Paris, FR
Palathinkara S. Vinod - Stafford TX
J. Ernest Brown - Houston TX
Ronnie L. Thomas - Sugar Land TX
Assignee:
Schlumberger Technology Corporation - Sugar Land TX
International Classification:
E21B 4326
US Classification:
166281, 166283, 166309, 507240, 507422
Abstract:
The improved recovery of hydrocarbons from subterranean formations by hydraulically fracturing a subterranean formation is accomplished. Fracturing fluids using a viscosifying surfactant fluid containing viscosifying micelles, for example, wormlike micelles, are useful to improve recovery of hydrocarbons and limit the loss of fracturing fluid into the formation fracture face. The invention further relates to novel fracturing and acidizing methods useful for increasing hydrocarbon production, limiting water production, resisting fracturing fluid loss into the subterranean formation, and reducing the equipment requirements in mixing and pumping fracturing fluid. The action of viscosifying micelles of surfactant in aqueous zones of the subterranean formation diverts fracturing fluid or acid from the aqueous zones to the hydrocarbon-bearing zones and also facilitates the flowback of increased amounts of hydrocarbons once a fractured well is placed back on production. These methods selectively block the pore structure in a water-bearing zone and do not blocking the pore structure of a hydrocarbon zone at the formation face. The step for selectively blocking forms a plug of a viscous fluid containing viscosifying micelles in the pore structure of the water-bearing zone at the formation face.

Method For Preparing Improved High Temperature Fracturing Fluids

US Patent:
6820694, Nov 23, 2004
Filed:
Jul 10, 2002
Appl. No.:
10/192046
Inventors:
Dean Willberg - Sugar Land TX
Michaela Nagl - Houston TX
Assignee:
Schlumberger Technology Corporation - Sugar Land TX
International Classification:
E21B 3100
US Classification:
1663085, 507903, 507922
Abstract:
The present invention related to a method for fracturing subterranean formations including the steps of (a) providing a water source; (b) adding a crosslinking agent to said water source; (c) adding a polymeric component to said water to create a fracturing fluid; (d) pumping said fracturing fluid into said formation. The fluid may contain an acrylamide-acrylate copolymer and any suitable number of additives. The additives are preferably combined with the water source to form an additive stream, to which the polymer is later added.

Methods And Fluid Compositions Designed To Cause Tip Screenouts

View page
US Patent:
6837309, Jan 4, 2005
Filed:
Aug 8, 2002
Appl. No.:
10/214817
Inventors:
Curtis L. Boney - Houston TX, US
Dean M. Willberg - Sugar Land TX, US
Assignee:
Schlumberger Technology Corporation - Sugar Land TX
International Classification:
E21B 43269
US Classification:
1662802, 166281, 1663081
Abstract:
In stimulation treatments to increase the production of hydrocarbons from subterranean formations, especially in treatments including hydraulic fracturing followed by gravel packing, desirable short wide fractures are created and filled with proppant by deliberately including in the first fluid/proppant slurry pumped a sufficiently high concentration of a bridging-promoting material, such as fibers, that reduces the mobility of the slurry when it dewaters so that screenout at or near the tip occurs.

Real-Time Automated Heterogeneous Proppant Placement

US Patent:
7451812, Nov 18, 2008
Filed:
Dec 20, 2006
Appl. No.:
11/613693
Inventors:
Iain Cooper - Sugar Land TX, US
Dean M. Willberg - Tucson AZ, US
Matthew J. Miller - Cambridge, GB
Assignee:
Schlumberger Technology Corporation - Sugar Land TX
International Classification:
E21B 43/267
US Classification:
1662501, 16625001, 1662801, 1663081, 703 10
Abstract:
A system and a method for heterogeneous proppant placement in a fracture () in a subterranean formation () are disclosed. The system includes a delivery system () for delivering proppant and treatment fluid to the fracture (), a sensor () for measuring geometry of the fracture and a computer () in communication with the sensor (). The computer () includes a software tool for real-time design of a model () for heterogeneous proppant placement in the fracture () based on data from the sensor () measurements and a software tool for developing and updating a proppant placement schedule () for delivering the proppant and treatment fluid to the fracture () corresponding to the model. A control link between the computer () and the delivery system () permits the delivery system () to adjust the delivery of the proppant and treatment fluid according the updated proppant placement schedule.

Heterogeneous Proppant Placement In A Fracture With Removable Channelant Fill

View page
US Patent:
7581590, Sep 1, 2009
Filed:
Dec 8, 2006
Appl. No.:
11/608686
Inventors:
Timothy Lesko - Novosibirsk, RU
J. Ernest Brown - Cambridge, GB
Dean M. Willberg - Tucson AZ, US
Ivan Kosarev - Dolgoprundy, RU
Anatoly Medvedev - Moscow, RU
Assignee:
Schlumberger Technology Corporation - Sugar Land TX
International Classification:
E21B 43/267
US Classification:
1662801
Abstract:
A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant () and proppant-spacing filler material called a channelant () through a wellbore () into the fracture (), heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands () spaced apart by the channelant (), and removing the channelant filler material () to form open channels () around the pillars () for fluid flow from the formation () through the fracture () toward the wellbore (). The proppant and channelant can be segregated within the well treatment fluid, or segregated during placement in the fracture. The channelant can be dissolvable particles, initially acting as a filler material during placement of the proppant in the fracture, and later dissolving to leave the flow channels between the proppant pillars. The well treatment fluid can include fibers to provide reinforcement and consolidation of the proppant and, additionally or alternatively, to inhibit settling of the proppant in the treatment fluid.
