Topic:                  Are You Fracking the Diatomite? Matrix Cyclic Steam Injection in the Diatomite Zone, Orcutt Field, Santa Barbara County, California

Abstract:                 

Discussed is the continued success seen with steam injection tracking and monitoring using modified Hall plots and their derivatives proposed in 2013. Matrix flow in the diatomite is confirmed using industry accepted analytical calculations for determining a host of parameters including steam zone flow capacity (kh), steam injection rates that avoid formation parting, and the zone of endangering influence (ZEI) needed for UIC approvals. Evidence of pore dilation and unavoidable skin effects are cited.


Modified Hall plots provide an alternative method for determining the formation parting flow rate (FPR) in lieu of the formation parting pressure (FPP). Fundamentally, step-rate tests are not reliable (SPE 169513-MS) for determining the FPP. An actual CSS well case history is used.

The study shows there to be a wide range of diatomite steam zone injection conditions that do not cause parting or fracturing of the diatomite by steam injection. Real-time Hall plots also provide valuable insights as to how injection zone properties change as the project matures. The project monitoring protocols originally described in a 2013 paper continue to be used with safe and reliable outcomes confirmed by thousands of successful project CSS injection operations.

Topic:                  On Repurposing Oil and Gas Wells to Geothermal Wells

Abstract:                 

The number of abandoned oil and gas wells are growing over millions, significant costs are imposed to companies and government for decommissioning these wells. However, it would be very encouraging for the oil and gas industry to take advantage of these wells and use them as a source of geothermal energy. Huge upfront costs have always been a major obstacle for the development of geothermal energy. As a rule of thumb, a quarter of the costs for harvesting geothermal energy is going toward drilling and one third of the costs is spent for completions. One obvious solution is avoiding these costs by repurposing existing oil and gas wells to generate geothermal power at the end of their economic production life. In some regions of extensive hydrocarbon explorations, the geothermal gradient can be very steep, providing potential well candidates for conversion. Taking into consideration the local energy demand, potential market, existing infrastructure, and technical challenges, a conversion strategy for the existing wells is discussed specially in terms of the wellbore integrity requirement and steps to ensure hydrocarbon containment during the heat extraction process. Potential challenges in inspection and preparation of these wells in terms of well integrity and productivity with possible remedies will be discussed in this presentation.
