Well intervention operation with High H2S for gas wells in presence of water aggravate corrosion and H2S cracking significantly for any type of metallic material. Special down hole plugs, wire line, E-line and sealing elements of pressure control...

... saturation, relative permeability (Kr) and capillary pressure (Pc) curves. Steady-State coreflooding and PCRI experiments are performed at reservoir conditions, while centrifuge runs are done at 80°C. The Steady state experiments are executed on both single plug and composite core samples. Numerical...

... float equipment package, comprised of a retained flapper valve and ball activation system, allowed the casing to autofill through large flow by areas, tolerant to the LCM in the well, while maintaining compatibility with the subsurface release plug system necessary for deepwater operations. The system...

... treatments and surfactant flooding was selected and executed for three injectors in the interested pilot block. For the fourth injector, only surfactant flooding was used to compare. Lab results of conformance control core flooding tests showed the efficiency of plugging and a good fluid diversion...

... set up. The LCM combination was also weighted with barite to determine if the sealing performance was consistent for anticipated applications. The LCM plug formed in the test set up was evaluated for the maximum differential pressure it could withstand in wet conditions, as well as its compressive...

... precipitation occurred in examined water mixtures after KMnO 4 and oxygen scavenger were added. Coreflood experiments showed no permeability reduction in the core plugs although with white solid precipitation noticed on the face of the plugs which was attributed to the precipitation of the insignificant amount...

... Abstract In order to optimize Completion installations by eliminating Intermediate Completion, reducing rig time, and preventing fluid loss, a project was initiated to develop a barrier glass plug with bypass capability. The plug allows self-filling of the tubing while running in hole...

... of the vent screen assembly, and the gravel pack slurry was bullheaded from surface. Excess sand was removed in the fourth CT run, followed by retrieval of the vent plug from the top of the screen assembly. An upper packer was connected to the screen assembly in the next CT run, and then hydraulically set...
