A field method for measuring solids sizes on the job. It is simple and easy to use and should improve the efficiency of solids control. There will be some sacrifice in accuracy; however, only the relative weight percentage distribution of the particles is needed to allow constructive steps to remove these particles.
Oil slop & sludge waste equipment manufactured by aipu solids control are working on Karamay, Xinjiang Uygur Autonomous Region, China.
The application of polymer muds has been hindered by two criticisms. First, they are difficult to run because mud-engineering maintenance guidelines are very different from conventional bentonite mud systems. Second, they are less solids-tolerant than dispersed or lime-based systems. Consequently, these muds often have proved uneconomical for drilling geologically young and highly dispersive shales or for drilling with high mud weights (greater than 14 lbm/gal [greater than 1700 kg/m3]).
The 6 1/8” section is drilled as high slanted 84º in lower reservoir to get more exposure with production zone. After drilling, pressure points were taken to design completion fluid along with roller reamer to make sure hole is smooth. Production / plugging screen test (PST) is performed for the Reservoir Drilling Fluid (RDIF) prior to run ICD (Inflow Control Device) screens to make sure that, solids present in RDIF should not plug screens.
