摘要:
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.

A wellbore apparatus and method comprising a first wellbore tool having a primary flow path and at least one secondary flow path and a second wellbore tool having a primary flow path and secondary flow path. A radial center of the primary flow path in the first wellbore tool is offset from a radial center of the primary flow path in the second wellbore tool which comprises a crossover joint connecting the first wellbore tool to the second wellbore tool having a primary flow path fluidly connecting the primary flow path of the first wellbore tool to the primary flow path of the second wellbore tool, and at least one secondary flow path fluidly connecting the at least one secondary flow path of the first wellbore tool to the at least one secondary flow path of the second wellbore tool.

摘要:
A method for completing a wellbore in a subsurface formation includes providing a sand screen assembly representing one or more joints of sand screen, joint assembly, and packer assembly. The packer assembly has at least one mechanically-set packer with at least one alternate flow channel. The sand screen assembly and joint assembly also each have transport conduits for carrying gravel slurry, and packing conduits for delivering gravel slurry. The method also includes running the sand screen assembly, connected joint assembly and packer assembly into the wellbore, and setting a sealing element of the packer assembly into engagement with the surrounding wellbore. Thereafter, the method includes injecting gravel slurry into the wellbore to form a gravel pack such that a reserve of gravel packing material is placed above the sand screen assembly. A wellbore completion apparatus is also provided that allows for placement of the gravel reserve.

A method for completing a wellbore in a subsurface formation includes providing a first base pipe and a second base pipe. Each base pipe comprises a tubular body forming a primary flow path and has transport conduits along an outer diameter for transporting fluids as a secondary flow path. The method also includes connecting the base pipes using a coupling assembly. The coupling assembly has a manifold, and a flow port adjacent the manifold that places the primary flow path in fluid communication with the secondary flow path. The method also includes running the base pipes into the wellbore, and then causing fluid to travel between the primary and secondary flow paths. A wellbore completion apparatus is also provided that allows for control of fluid between the primary and secondary flow paths.
摘要:
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.
