LANDIVAR, Rodolfo; LOAIZA, Marco  and  VALENCIA, Raul. Optimized Well Drilling with a 1000 HP Rig in the PBHI-MDC Fields. Rev Politéc. (Quito) [online]. 2019, vol.43, n.1, pp.37-50. ISSN 2477-8990.

The fields where the present work was carried out are located in the Oriente Basin of Ecuador, where wells were drilled up to 2015 with at least 1500 HP Rigs; for 2016 the Operating Company took the challenge of optimizing drilling costs, evaluating the option of using a lower capacity Rig, selecting a 1000 HP Rig, which presented disadvantages in torque capacities, lifting loads, capacity of tables and equipment in general compared to a 2000 HP Rig, but through the analysis of previously drilled wells, effective and efficient planning, design of wells according to the drilling equipment, generation of a detailed risk matrix of drilling activities with prevention and mitigation actions, complemented by an operational management focused on the identification of risks and opportunities for continuous improvement, in addition to the application of state-of-the-art technologies, allowed the viability of the use of this equipment. Up to December 2017, 4 modified "J" directional wells were drilled to an average depth of 10,882 feet, achieving cost and time savings, validating the drilling with a 1000 HP drill.
