A simple and economical surface solids control method to complement the downhole systems becomes necessary when we desire to reduce viscosity, yield point, gel strength, total solids, concentration of drilled solids, and low micron-size material. This aim will be achieved when we are able to partially reject the undesirable materials from the drilling fluid system.

Steam Assisted Gravity Drainage = SAGD “Steam-assisted gravity drainage (SAGD; “Sag-D”) is an enhanced oil recovery technology for producing heavy crude oil and bitumen. It is an advanced form of steam stimulation in which a pair of horizontal wells is drilled into the oil reservoir, one a few metres above the other. -wikipedia
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.
