US Patent:

8272438, Sep 25, 2012

Filed:

Sep 27, 2007

Appl. No.:

12/519226

Inventors:

John Cook - Cambridge, GB
Marc Thiercelin - Dallas TX, US

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 47/06

US Classification:

16625007, 16625011, 16625017, 175 50, 7315251, 7315253

Abstract:

Systems and methods are disclosed for accurately determining a pore pressure of a subsurface formation () penetrated by a wellbore (). The systems and methods provide for measuring pressure and temperature at a measuring location proximal to the wellbore for a predetermined amount of time, storing the measurements, communicating the measurements and processing the pore pressure from the pressure and temperature measurements. The measuring location may be a location in a channel () drilled from the wellbore into the formation.

International Classification:

G06G 7/48

US Classification:

Abstract:

Methods and systems for characterizing hydraulic fracturing of a subterranean formation based upon inputs from sensors measuring field data in conjunction with a fracture model. Such characterization can be generated in real-time to automatically manipulate surface and/or down-hole physical components supplying hydraulic fluids to the subterranean formation to adjust the hydraulic fracturing process as desired. The hydraulic fracture model as described herein can also be used as part of forward calculations to help in the design and planning stage of a hydraulic fracturing treatment. In a preferred embodiment, the fracture model constrains geometric and geomechanical properties of the hydraulic fractures of the subterranean formation using the field data in a manner that significantly reduce the complexity of the fracture model and thus significantly reduces the processing resources and time required to provide accurate characterization of the hydraulic fractures of the subterranean formation.

US Classification:

367 38, 367 69

Abstract:

Methods and systems are described for measuring effects of a hydraulic fracturing process. The techniques can utilizes cross-well seismic technology, such as used in Schlumberger's DeepLook-CS tools and service, or in some case surface to borehole or borehole to surface seismic technology. The downhole seismic sources at known locations can be conventional sources or can be other types of equipment operating at known locations such as perforation guns. The source is activated or swept creating energy which is transmitted through the formation. The energy is recorded at the receiver array and processed to yield a tomographic image indicating changes in the subterranean formation resulting from the hydraulic fracturing process. The process can be performed pre and post hydraulic fracture stimulation to generate a difference image of propped fractures in the reservoir.
