| Abstract |
ENDE, the national electricity company of Bolivia is planning to build a 100 MW power plant in the Sol de Mañana geothermal field. There already are 5 drilled wells (they will make up) and nowadays ENDE is planning to drill 25 new wells (16 production wells and 9 reinjection wells) to extract geothermal energy in two units (50 MW each one). In order to achieve this ambitious goal, it will be required to hire a company that is supposed to manage all the drilling operations on the field (Building and design of the access roads, pads, drilling, well-testing, etc.), this service is known as Integrated Drilling Services. In order to help find the best and more suitable company for this project, a one sheet program has been developed to show and illustrate to companies the key points of the services they must carry out. It is divided into two pages, the front face shows all the operations for the drilling service such as general information of the field, depth of the geological structures, well diameter, BHA, cement program, casing configuration, drilling fluids, and risks. This part gives an understandable summary of the drilling sequence and basic considerations. The back face shows all the well-testing procedures and equipment, wellheads, triaxial stresses for the casing, and a detailed scheme of all the services that will be required to perform this enormous project. This program is just a brief compilation of the main operations required for ENDE. Besides, this illustrative piece of paper is needed for a quick understanding of the necessities and as an advantage it could be carried everywhere. |
