  • Bailey, Alan; Gollmyer, Eric; Mitchell, Sarah; Pye, Stephen; Rickard, Bill; 2010; Casing Protection  for Geothermal Wells, Presented at the Geothermal Resources Council 35th Annual Meeting.
    • Drilling and completing geothermal wells in the Salton Sea Geothermal Area represents a unique challenge.  Acidic, corrosive produced fluids, combined with high temperatures and the requirement for a long service life often necessitate high cost, corrosion resistant casing materials.  Unfortunately, these materials can be susceptible to wear.  Therefore, casing protection becomes vital in providing a long service life.  Wear must be minimized, because the resulting damage can be impossible to repair.  Rotating drill pipe protectors have been run to protect casing for years, but with shallow casing set points and long bit runs, maintaining protection of the casing results in these protectors being run into open hole.
  • Bailey, Alan; Howard, Wendell; Kolker, Amanda; 2010; The 2010 Akutan Exploratory Drilling Program: Preliminary Findings, Presented at the Geothermal Resources Council 35th Annual Meeting.
    • In 2010, a geothermal exploratory drilling program was conducted on Akutan Island, Alaska. The purpose of the drilling program was to obtain temperature gradient data to constrain resource capacity. The wells were designed to allow long-term monitoring and possible testing of the Akutan geothermal field.  The 2010 drilling operations were carried out using wireline core equipment and were supported by helicopter. 
  • Niggeman, Kim; Abraham, Samuel; Rickard, William; Morris, Alexander; Hernandez, Rafael; 2010; Foamed Cementing Geothermal 13 3/8 inch Intermediate Casing; NGP #61-22, Proceedings World Geothermal Congress 2010. Bali, Indonesia, 25-29 April 2010.
    • This paper documents the analysis, planning, and execution of foamed-cementing operations used to successfully perform primary 13 3/8-in. casing cement work. Previous cementing practices are presented, as well as the advantages and design of foamed cementing for this application. A post-job analysis and cost comparison of foamed versus conventional cementing is also presented.
  • Rickard, Bill; Samuel, Abraham; Spielman, Paul; Otto, Michael; Nickels, Nic; 2010; Successfully Applying Micronized Cellulose to Minimize Lost Circulation on the PUNA Geothermal Venture Wells, presented at the Geothermal Resources Council 34th Annual Meeting.
    • The PUNA Geothermal Venture wells are located on the Big Island of Hawaii. The project site is close to the Kilauea Volcano with a high geothermal gradient resulting in static bottomhole temperatures above 600 ̊F. Lost circulation can be a problem in drilling these wells, as it is costly, causes delays, exacerbates hole instability and frequently results in stuck pipe. This paper discusses the drilling operation, drilling fluid and the application of micronized cellulose on these geothermal wells.
  • Spampanato, Terence; Parker, Dean; Bailey, Alan; Ehni, William; 2010; Overview of the Deep Geothermal Production at the Peppermill Resort, presented at the Geothermal Resources Council 34th Annual Meeting, Reno, Nevada
    • In 2009, Peppermill Resort Casino expanded its use of geothermal waters by drilling at depth into the Moana geothermal resource. Geothermal Resource Group drilled two new deep wells drilled in 2009 and 2010 to provide production and injection capacity for heating and cooling the resort, resulting in over one million dollars per year in energy cost savings.
  • Rickard, Wm. M.; 1985; Foam Cement for Geothermal Wells, Union Geothermal of Indonesia, published in 1985 International Symposium on Geothermal Energy, Part 1, Geothermal Resources Council, ISBN 0-934412-59-6.
    • In perhaps the first paper ever published on foam cement for geothermal wells, Bill Rickard shows how foam cement is versatile and economical ultralight cementing slurry that is useful in fragile formation intervals and lost circulation areas.  Diagrams, charts and tables illustrate the technology in detail.
