Douglas Chirinos
Petroleum Engineer from Louisiana Tech University, Louisiana USA.
Extensive international experience in Mexico, Trinidad, Tobago, Colombia, Argentina, and Venezuela, working for Pemex, CBM, Halliburton, Petrotrin Trinidad, Vetra, Petrobell, BRC, IGT Consultants, Galo Pacific, and PDVSA E&P.
Specialist in wells, workovers, reservoirs, and production facilities in heavy, medium, light oils and gas, clastic and fractured carbonate reservoirs, well optimization, artificial lift, gathering and production facilities, cost estimations onshore and offshore, water injection operations, separations and clarification technologies for disposal and secondary recovery, economics & risk analysis.
Douglas lectures in association with MineaOil Ltd.
This course is designed to provide the fundamentals and concepts to design well interventions and repairs in oil and gas producer and injector wells, including disposal and enhancing oil recovery dedicated wells. The course describes methodologies to identify opportunities to carry out Workovers, understand the artificial lift systems, when and how to change producing zones, and how to prepare a work over proposal. Formation damage mechanisms, Skin factor concepts and types and removal methods are described.
Chemical Stimulations, Matrixial and Conventional in sandstones, carbonates, and shaly sands to increase the oil and gas rates, hydraulic fractures, perforation, re-perforations, and or changing productive zones. Diagnostic methods to monitor the injectivity in injector wells, and methods to increase the injectivity; the factors affecting oil and gas well productivity are also reviewed with the aim to understand the factors that drive the productivity and understand when and how to apply technologies to optimize oil and gas production rates and final recovery.
