| Abstract | Focusing in the goal to overcome the lack of geothermal projects development in Mexico during the past two decades the Inter-American Development Bank (IDB) designed the Program of Risk Transfer and Financing for Geothermal Energy. The objective is to isolate the drilling risk during the geothermal projects development. Besides BID, participates the Clean Technologies Fund (CTF) along with interaction of Mexican Government Institutions: Ministry of Energy (SENER), Nacional Financiera (Mexican development bank NAFIN) and the National Institute of Electricity and Clean Energies (INEEL). This program will be applied in Mexican projects to promote continuity of geothermal exploration in Mexico. Moreover, it includes financing for private investors for field development until construction in permissioned or concession areas is completed. INEEL acts as the technological arm of IDB and has leaded the two main lines of it: Drilling bidding process and Call for field developers. The bidding process for drillers was focused in select those that offer the lowest prices for drilling geothermal wells up to 3500 meters depth and most senior experience. Process also included a detailed analysis of items such as technical and administrative related with drilling activities of geothermal wells: drilling rig capacity, power, accessories availability, tubular goods, professional and technical staff experience, financial stability, administrative reliable. Those, are some of the items considered in drillers evaluation besides their costs offered. The call for field developers was focused to those having permissioned or concessioner zones by SENER. INEEL designed an evaluation pattern for them which considers: Geoscientific studies, drilling wells program, Complete design of the project considering National development plan, applications to develop economically nearby communities, environmental protection, business experience and its professional and technical staff skills. In this paper is shown a methodology to carry out an integral project that supports selection of geothermal well drillers with low costs in theirs offers and investor developers which show high successful possibilities in their permissioned or licensed fields. Also it includes our findings related to drilling price ranges as function to depth compared worldwide. |
