    摘要： A method of forming an elevated pressure proppant-containing fracturing fluid for direct injection into a wellbore that reduces exposure of a substantial amount of the pumping equipment to the abrasive effects of proppant, as compared to conventional pumping equipment. The method includes providing a high pressure fluid stream to a nozzle having an inlet and an exit; accelerating the high pressure fluid stream through the nozzle from the inlet to the exit to increase the velocity thereof; providing a low pressure stream comprising a proppant to a suction chamber, the suction chamber positioned adjacent the nozzle exit; and mixing the low pressure fluid stream comprising a proppant with the high pressure fluid stream to form an elevated pressure proppant-containing fracturing fluid. A method for fracturing and a system for forming an elevated pressure proppant-containing fracturing fluid for injection into a wellbore are also provided.

    摘要： Method for completing a wellbore in a subsurface formation includes providing a sand control device representing one or more joints of sand screens, and a packer assembly along the joints with at least one mechanically-set packer with at least one alternate flow channel therein. Running the packer assembly and connected sand screen into the wellbore, setting a mechanically-set packer into engagement with the surrounding wellbore, injecting gravel slurry into the wellbore to form a gravel pack. An elongated isolation string is run into the sand control device across the packer assembly with valves that serve as an inflow control device. Thereafter, seals are activated around the isolation string and adjacent the packer assembly. A zonal isolation apparatus allows flow control to be provided above and below packer assembly.

    摘要： A system and/or methodology that unifies a telephonic communication component and/or system with a data (e.g., messaging) server component and/or system. The system can facilitate telephonically accessing rich information in the server (e.g., messaging server). This rich information can include email content, calendar content, contacts information, or the like. Moreover, with access to an application programming interface, the invention can add functionality to initiate email communications as well as to accept or cancel meetings. Furthermore, the invention can synchronize messages of disparate formats. By way of example a user can set an “Out of Office” (OOF) status on both an email systems and telephone voicemail system from one location in one action. In another aspect, it will be appreciated that any message or data component can be analyzed, transformed, matched and/or communicated from one system to another (e.g., server to telephone) in accordance with the subject invention.

    摘要： In a well related to the production of hydrocarbons, an injection apparatus including: a base pipe including a radial port; an in-flow control device including a flow restriction device and a housing, with the housing being external and concentric of the base pipe. The housing includes a closed end portion and an open, opposite end portion and a housing channel communicating the opposite end portion. The flow restriction device is disposed at an intermediate location along the housing channel and adapted to control a rate of flow along the housing channel. A fluid transmissive screen is concentric of the base pipe and extends from the open, opposite end portion of the housing. A check valve assembly is interposed between the opposite end portion of the housing and a screened space.
