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.
ThermaSTONE
ThermaSTONE thermally responsive cement is designed with optimal mechanical properties. This technology allows the cement to withstand the extreme pressures and temperatures experienced during steam injection operations for heavy oil wells.
The self-healing properties of this cement provide a durable cement sheath, long-term zonal isolation, and reliable cement sheath repair to preserve well integrity.
There are a variety of sand control and screens available depending on the requirements of the heavy oil project. However, if cold production with sand (CHOPS) is the primary means of recovery then sand control is not a part of the completion strategy. In this case the sand needs to flow or be pumped to the surface.
Stabilizes the sand and accommodates the wider variety of particle sizes encountered in unconsolidated formations without clogging.
Proven to increase production efficiency. Having the right slot width is critical to an efficient design. If too big, sand influx is a problem and even a minor sand influx can have long-term consequences. Slots that are too small can cause plugging.
ICDs make it easier to manage flow into the well, and performance is independent of viscosity.
