Significant value in well construction
The correct placement of various well types - producers, injectors, and monitors –and their construction quality impacts the immediate and long-term profitability of any heavy oil field. With the knowledge that a typical heavy oil field will likely be under thermal recovery, careful consideration must be given to applying technologies that will yield significant value in this challenging operating environment.
The timely commissioning of facilities and recruiting and training staff helps to optimize production levels while meeting safety and environmental standards, thus ensuring consistent product quality throughout the operation.
There are three main objectives when constructing and completing heavy oil wells: accurate well placement, wellbore stability and longevity, and production efficiency.
In the unconsolidated sand environments common to many heavy oil reservoirs, high viscosity causes destabilization of the rock formation and mobility issues. Cements with a low Young’s modulus can deliver mechanical properties appropriate for downhole thermal stress environments offering better lifelong zonal isolation.
