The field produced 2.94 thousand barrels / day in April, a smaller volume than the first month of production
Oil production in the Papa-Terra field in the Campos Basin reached its lowest level in April, even in relation to the first month of production in November 2013. According to BE Petróleo survey, the field produced an average of 2.94 thousand barrels per day of oil that month in a system designed to produce 140,000 barrels per day.
With Petrobras (operator) and Chevron as concessionaires, the field currently produces three wells, according to ANP data, linked to two platforms: the FPSO P-63, the country’s first TLWP, and the P-61 which operates a tender assisted drilling Rig (TAD).
Papa-Terra produced 34,000 barrels per day in the initial phase of its development. Since then, production has been dropping month by month until it reaches the historic floor in April. In May and June, the it registered a slight recovery but still at levels close to the first month of production.
Water production, in turn, is increasing, reaching the level of 19 thousand barrels / day in June this year. It is worth remembering that this volume occupies liquid processing capacity in the platforms, reducing oil recovery.
At the end of 2017, Petrobras was planning to implement a pilot project of polymer injection in the field, aiming to increase the efficiency of the project. Asked about the progress of the project, the company did not respond to the request in time for the closing of the report.
The objective of the polymer injection project, developed by Petrobras in Cenpes, is to raise the viscosity of the water by increasing the efficiency of the sweeping, that is, the drag of the oil by the water produced by the field. Oil production was expected to increase.
“The pilot will consist of the injection of water viscosity by means of polymers in a injector well connected to the reservoir, in order to validate the studies carried out by Cenpes, supporting the expansion in case of success. It is worth noting that this is a very recent technology in the world oil and gas industry and there are still studies being carried out regarding the application of the method in the field of Papa-Terra, “informed Petrobras in 2016 when the project was approved by ANP.
In August 2015, the ANP determined that Petrobras would present a new development plan for the field. The determination was revoked after Petrobras presented the polymer injection project.
