Cyclic Steam Simulation (CSS)

CSS technology unlike SAGD only requires one horizontal well-bore to be drilled for both injection and production; CSS is often called "huff and puff" and closely resemble steam flood operations. The first phase of CSS is obviously the injection portion which is used to heat the bitumen to the point where it is mobile enough to flow to the well-bore. The second phase begins at the point the steam injection is switched off and pumping of the well begins through the same well-bore. The two phases of CSS, injection and production, represent one complete cycle of the operation. The beginning of the next injection phase commences when oil production falls to a level where it is no longer economic to produce. Most CSS wells are designed to produce 7-10 complete cycles.

Regent in collaboration with its customers has advanced CSS, with the use the Regent's technologies of TRS™ liner, Hot Pig™ cleaning, FCH thermal liner hanger and the FCJ inflow control device, to dramatically increase production rates and decrease injection costs.

Advantages of CSS:

• Lower initial capital costs by reducing the well count
• Smaller environmental footprint
• Thinner reservoirs become more accessible
