Dr. Kayad Moussa AhmedGeneral Manager of Djibouti Geothermal Development Office

    Dr. Kayad Moussa, Ph.D. in Hydrology and Hydrogeology and reservoir, School of Mines in Paris, is the Managing Director of Geothermal Geothermal Development Office, (ODDEG) is a renowned geothermal expert, distinguished scholar and accomplished manager. He has 10 years’ experience in developing and implementing major geothermal projects, most of which are thriving in Djibouti. Since 2014, Kayad Moussa has been the National Coordinator for the Assal Geothermal Project in Djibouti. The objective of the project is to drill and test four deep (2.5 km) wells for geothermal resource exploration in the Fialé Caldera area.

    Parallelly he was the head of the drilling program who have been executed in Galla-Le-Koma, (Assal), the only drilling program who have been executed in Djibouti for 30 years. In 2008 Dr. Kayad Moussa joined the Center for Studies and Research of Djibouti (CERD) and participated in research on a wide range of surfaces studies to identify geothermal fields throughout the country. As part of his exploration work, he participated in geological, and geophysical surveys, and carried out geochemical sampling and analyses of hot springs and fumaroles at various sites.

    Dr. Kayad Moussa has participated in various geothermal conferences and published and presented papers and reports in both English and French. From 2010 to 2013 he worked on the European project known as “GEISER” (Geothermal Engineering Mitigation of Induced Seismicity in Reservoirs). During this period, he updated and participated in the development of new program evaluation tools to measure the impact of coupled thermo-hydro-mechanical processes (THM) in EGS projects using a tool called “FRACAS”. Using this program, he modeled and numerically defined the relationship between induced seismicity and stress due to the cooling of rocks and increasing pressure in the reservoir. As part of this work, he set up a 3D stochastic model with geometric properties (radius, length, and orientation of fractures) and petrophysics parameters derived from field data obtained at the site of Rosemanowes, located in Cornwall, UK. As a result of this work, he proposed an innovative technique to mitigate induced seismicity during reinjection.
