It remains a challenge to control sand production from interfering in the production of oil and bitumen from unconsolidated formations in the upstream oil industry. The Wrapped Punch Screen (WPS), when applied under the conditions of open-hole and unconsolidated formations, can provide highly reliable sand control ability as well as lower costs, compared to the Wire Wrap Screen and the Premium Mesh Screen. It can also lead to a higher long term productivity compared to other open-hole completion methods. This is due to its stainless-steel construction that offers highly anti-corrosive and erosion-free advantages.
This study has investigated and compared different types of sand control screens commonly used in heavy oil reservoirs, including the slotted liner screen, the wire wrapped screen and the WPS screen in terms of the sand control ability, performance under pressure and cost in the manufacturing process. Two experiments were conducted to compare the pressure performance and fluid productivity of the slotted liner and WPS. Key comparisons were based on six main evaluation points that are detailed Chapter 3, which addresses design, and in Chapter 4, which provides a dynamic fluid production analysis.
