摘要： A stimulation technique is provided for use in an open hole well. The stimulation technique utilizes a system which comprises one or more isolation devices positioned to isolate desired regions of the open hole well. At least one release mechanism is used to provide controlled release of stimulation material to a desired wellbore region of the open hole well. Additionally, a protection mechanism cooperates with each release mechanism to prevent undesirable contact between stimulation material and the surrounding wellbore wall of the open hole well. In many applications, the entire system is deployed and operated during a single trip downhole into the well.

摘要： A stimulation system configured for use in open-hole wells. The system may alternatively or additionally be configured for multi-zone stimulation applications. The system includes assemblies which employ techniques and configurations for isolating recovery screens downhole even without the presence of well casing. In this manner protection may be provided from dowhnole contaminants such as water which might otherwise leak in from adjacent formation layers.

摘要： A technique includes running a lower completion assembly into a well in a single trip. The lower completion assembly includes a screen, a first valve and a second valve. The technique includes performing a gravel packing operation using the lower completion assembly, where performing the gravel packing operation includes running a service assembly into the lower completion assembly to operate the first valve. The technique further includes removing the service assembly from the well and subsequently installing an upper completion assembly in the well. The installation of the upper completion assembly enables remote control of the second valve of the lower completion assembly for purposes of regulating the production of fluid from the well.

摘要： A method and system are disclosed for low damage gravel packing. The method comprises: combining a carrier fluid and a solids mixture into a slurry, wherein the solids mixture comprises a plurality of particle size distribution modes such that a packed volume fraction exceeds 0.75; contacting a screen with leak-off control agent to form a bridge; positioning the screen and circulating the slurry through the wellbore in any order such that the solids mixture is deposited between the screen and the wellbore; degrading the degradable material to increase porosity and permeability of the pack; removing the bridge; and producing a reservoir fluid from the formation. The system comprises the slurry, a tubing string and slurry pump to position the screen and circulate the slurry to form the bridge on the screen.

摘要： Gravel packing of a wellbore penetrating a subterranean formation is carried out in a wellbore having a cased section and an uncased section that contains water-based drilling fluids. A first water-based displacement fluid that contains a shale inhibitor is introduced into the wellbore to displace the water-based drilling fluids from the uncased section of the wellbore. A second water-based displacement fluid is introduced into the wellbore to displace fluids within the cased section of the wellbore. A sand control screen assembly is run to a selected depth within the uncased section of the wellbore to facilitate a gravel packing operation. A gravel pack slurry containing gravel and a viscosified carrier fluid is introduced into the wellbore to facilitate gravel packing of the uncased section. The gravel packing operation may be carried without the use of shunt flow paths and with the use of a sand screen assembly having at least one diverter valve to divert fluid returns to facilitate prevention of pressure build up.

摘要： A method is disclosed for low damage gravel packing. The method includes combining a carrier fluid, a first amount of particulates, and a second amount of particulates into a slurry. The first amount of particulates have a first average size distribution and the second amount of particulates have a second average size distribution, and the first average size distribution is at least three times larger than the second average size distribution. The slurry includes particles which are at least partially degradable material, and with reactive solid constituents. The reactive solid reacts with the degradable material and/or a hydrolysis product of the degradable material. The method further includes positioning a screen in a wellbore, and circulating the slurry through the wellbore such that the first amount of particulates and the second amount of particulates are deposited on an outer surface of the screen.
