High-Temperature Well Cementing
“Exploring Geothermal and Oil and Gas Synergies”
March 30 - April 1, 2020
Wyndham San Diego Bayside, San Diego, California, USA
Call for Abstracts
The Geothermal Resources Council (GRC) together with the Society of Petroleum Engineers (SPE) invite you to present your latest technical work in High-Temperature Well Cementing at the special joint workshop.
Please submit your abstracts to Estela Smith at email@example.com. Call 530.758.2360 ext 102.
Deadline for submission of abstracts is December 1st, 2019.
The GRC together with the SPE are organizing a workshop on high-temperature cementing. Geothermal wells experience high temperatures at very shallow depths and are required to cement casing across the entire length of each casing string set in the well. The large temperature variations over the lifecycle of thermal oil recovery wells, and the very high temperatures of high-pressure/high-temperature (HP-HT) oil & gas wells drilled to ever greater depths, continue to push cement selection and placement technologies. All of these environments pose unique challenges to successful well completion. Cementing is crucial to ensure proper well integrity for the life of production and injection wells in these HT applications.
The GRC and the SPE have decided that a joint workshop would enable both industries to share their experiences, technologies, technical procedures and best practices on this important aspect of well completion. The workshop will highlight cement formulae and slurry blends, placement methods, remedial procedures and result evaluations. Case studies will be discussed and analyzed.
All drilling personnel, both geothermal and oil & gas drilling and production engineers, well-site supervisors, cementing engineers and interested personnel are welcome to attend and participate.
If you would like to chair any of the sessions, then please contact us. We would like to have two chairs for each session, one from the geothermal industry and one from the oil & gas industry. The chairs for each session will be required to assist the committee in obtaining presenters. Please volunteer.
Please contact us if you are interested in presenting in a session at the workshop. If you have a case history that you would like to present and would interest the attendees, please feel free to inform us and plan to present.
Please plan to attend.

Invited presenters or voluntary presenters with pertinent subject matter that they would like to present. Each of these presenters will need to submit their subject matter for approval several week prior to the workshop.
- Panel Discussion
Conclusion of the workshop will be a panel discussion to review all presented matter to include questions and answers as well as any concluding remarks. All presenters should be present to participate in these final discussions.
