Solids Control and Waste Management for SAGD

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

Prdocution / Plugging Screen Test (PST) Guidelines

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.
