Oil and gas company OGX has announced positive data from its wells located in the Tubarão Azul Field, offshore of Brazil, after a series of tests.
The company said that OGX-26 and OGX-68 wells tested flow rates ranging between 4,000-18,000 barrels a day, at the onset of an extended well test programme.
After five months of tests, the company has defined an ideal flow rate of 5,000 barrels of oil equivalent each day, per well.
OGX is replacing the centrifugal submersible pump in OGX-26 well, where production has been stopped, to accommodate production beyond the ideal flow rate.
Floating production, storage and offloading unit OSX-1 has been producing 7,400 barrels of oil equivalent each day from the OGX-68 well during the last five days, indicative of satisfactory levels of pressure in the reservoir.
OGX said that the two producing wells and two injection wells will be connected to FPSO OSX-1, within the next 12 months.
Chemical hydraulic fracturing and other industry techniques will be used to increase oil production at the field, where natural fractures in the reservoir connecting OGX-26 and OGX-68 were identified.
OGX remains confident it will recover 110 million barrels of oil equivalent at the Tubarão Azul field.
