A Novel Sand Control Testing Facility to Evaluate the Impact of Radial Flow Regime on Screen Performance and its VerificationDownload
Optimum design of the sand control devices in oil sand reservoirs plays a vital role in minimizing the sand production and increasing the reservoir productivity in Steam-Assisted Gravity Drainage (SAGD) operations. Various sand control testing facilities have been developed to evaluate the...
Sand control devices (SCDs) such as Slotted Liners (SLs) have been playing a crucial role in sand production for Steam Assisted Gravity Drainage (SAGD) operations. Lately, optimizing and selecting the proper design of SCDs in the laboratory to quantify and qualify the SCD’s performance is gaining...
Heavy oils and extra heavy oils in Alberta that are currently extracted through thermal recovery primarily employ Steam Assisted Gravity Drainage (SAGD). Sand control devices (SCDs) such as Slotted Liners (SLs) and Wire Wrap Screens (WWSs) have been used extensively in wells producing from...
Steam Assisted Gravity Drainage (SAGD) is a thermal recovery technology currently employed to extract heavy oil and high viscosity bitumen from Alberta oil sands. Due to the unconsolidated nature of oil sands, SAGD wells are prone to producing sand, hence, requiring sand control devices to...
Steam Assisted Gravity Drainage (SAGD) is the primary thermal recovery technology currently employed to extract heavy oil and high-viscosity bitumen from Alberta oil sands. In the nearwellbore region, the initial stresses are nearly zero, and as the SAGD chamber grows, the stresses tend to...
Experimental and Numerical Study into the Performance Assessment of Stand-alone Screens in Steam Assisted Gravity Drainage OperationsDownload
Sand production is a significant issue for weakly consolidated and unconsolidated formations. Sanding can erode the wellbore and surface facilities and plug the wellbore. In SAGD operations, wellbores are typically completed by stand-alone screens such as slotted liners (SL), wire-wrapped screens...
The quantification of fines migration in the vicinity of sand control screens in SAGD wells is of paramount importance to operating companies, who require the wells to operate under optimum conditions for a period of 10-15 years. Fines migration can lead to the plugging of pore spaces...
