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. | ||||||

184 | HIGH-RATE INJECTION SCREEN WITH CHECKABLE PORTS | EP15150122.8 | 2015-01-05 | EP2891763A2 | 2015-07-08 | Hall, Christopher A |
A screen assembly can be used for "gravel pack" or "frac pack" operations and can then withstand high rate injections. The disclosed screen assembly is able to withstand the flow of the packing operation by not allowing fluid passage from the annulus to inside the screen assembly. Then, the screen assembly can be opened and facilitate high rate injection for the life of the well. To achieve this, the disclosed screen assembly does not allow slurry flow to enter the screen assembly during the packing operation. Then, after the packing is completed, the screen assembly provides enough open flow area so that a high injection rate with solid content can be introduced into the annulus without eroding the screen. |

A well screen assembly has a base pipe and one or more screen sections attached to the outer surface of the base pipe. The assembly also has one or more shunt tubes attached to the base pipe via top and bottom rings. The shunt tubes can be attached to the screen sections via B-rings and may be transport tubes or packing tubes. Connections are used for securing a jumper tube to adjoining shunt tubes of adjoining screen sections of the wellscreen assembly, which may be used in open or cased holes. At a well site, the joints of the wellscreens have timed threads so that the various shunt tubes can be aligned with one another along the assembly as the joints are made up. The connections of the present disclosure allow operators to install a jumper tubes between shunt tubes at the joint without needing to tighten fasteners or assembly components. |

A technique facilitates performance of a treatment application in a lateral wellbore. The technique may be employed in an open lateral wellbore and comprises deploying a completion within the open wellbore wall of the lateral wellbore. A service tool is used in cooperation with the completion to perform a gravel packing or other well treatment operation while maintaining hydrostatic pressure on the open lateral wellbore to prevent collapse of the open lateral wellbore. A variety of features may be incorporated into the completion or used in cooperation with the completion to facilitate the well treatment operation while maintaining the hydrostatic pressure until completion of the desired gravel pack. |
