20110166843 | Method For Modeling Deformation In Subsurface Strata - A method for modeling deformation in subsurface strata, including defining physical boundaries for a geomechanical system. The method also includes acquiring one or more mechanical properties of the subsurface strata within the physical boundaries, and acquiring one or more thermal properties of the subsurface strata within the physical boundaries. The method also includes creating a computer-implemented finite element analysis program representing the geomechanical system and defining a plurality of nodes representing points in space, with each node being populated with at least one of each of the mechanical properties and the thermal properties. The program solves for in situ stress at selected nodes within the mesh. | 07-07-2011 |
20130248172 | Communications Module For Alternate Path Gravel Packing, And Method For Completing A Wellbore - A communications module and methods for downhole operations having utility with production of hydrocarbon fluids from a wellbore, including at least one alternate flow channel and an electrical circuit. Generally, the electrical circuit is pre-programmed to (i) receive a signal and, in response to the received signal, deliver an actuating command signal. The communications module further has a transmitter-receiver. The communications module allows a downhole tool to be actuated within a completion interval of a wellbore without providing an electric line or a working string from the surface. The tool may be actuated in response to a reading from a sensing tool, or in response to a signal emitted in the wellbore by a downhole carrier, or information tag. | 09-26-2013 |
20130248179 | Packer For Alternate Flow Channel Gravel Packing and Method For Completing A Wellbore - Apparatus and method for completing a wellbore including providing a packer having an inner mandrel, alternate flow channels along the inner mandrel, and a sealing element external to the inner mandrel, including connecting packer to tubular body, then running the packer and connected tubular body into the wellbore. In one aspect, the packer and connected tubular body may be placed along an open-hole portion of the wellbore. Tubular body may be a sand screen, with the sand screen comprising a base pipe, a surrounding filter medium, and alternate flow channels. The method includes setting a packer and injecting a gravel slurry into an annular region formed between the tubular body and the surrounding wellbore, and then further injecting the gravel slurry through the alternate flow channels to allow the gravel slurry to at least partially bypass sealing element of the packer. | 09-26-2013 |

20130277053 | Wellbore Apparatus and Methods For Multi-Zone Well Completion, Production and Injection - Completing a wellbore in a subsurface formation with packer assembly having first mechanically-set packer as first zonal isolation tool, and second zonal isolation tool comprises internal bore for receiving production fluids, and alternate flow channels. First packer has alternate flow channels around inner mandrel, and sealing element external to inner mandrel and includes operatively connecting packer assembly to a sand screen, and running into wellbore. First packer set by actuating sealing element into engagement with surrounding open-hole portion of the wellbore. Thereafter, injecting a gravel slurry and further injecting the gravel slurry through the alternate flow channels to allow it to bypass the sealing element, resulting in a gravel packed wellbore within an annular region between sand screen and surrounding formation below packer assembly. | 10-24-2013 |
20140231083 | Fluid Filtering Device for a Wellbore and Method for Completing a Wellbore - A sand control device for restricting flow of particles from a subsurface formation into a tubular body within a wellbore, the device being divided into compartments along its length, each compartment comprises a base pipe. The base pipe defines an elongated tubular body having a permeable section and an impermeable section within each compartment, also comprising a first filtering conduit and a second filtering conduit. The filtering conduits are arranged so that the first filtering conduit is adjacent to the non-permeable section of the base pipe, while the second filtering conduit is adjacent to the permeable section of the base pipe. | 08-21-2014 |
20140262260 | Sand Control Screen Having Improved Reliability - A sand control device is used for restricting the flow of particles from a subsurface formation into a tubular body within a wellbore during production operations. The sand control device is divided into compartments along its length that provide redundancy for particle filtration. Each compartment first comprises a base pipe. The base pipe defines an elongated tubular body having a permeable section and an impermeable section within each compartment. Each compartment also comprises a first filtering conduit and a second filtering conduit. The filtering conduits comprise filtering media and generally circumscribe the base pipe. The filtering conduits are arranged so that the first filtering conduit is adjacent to the non-permeable section of the base pipe, while the second filtering conduit is adjacent to the permeable section of the base pipe. | 09-18-2014 |
