The Copa-3 well was completed in the Carbonera C7 formation and is currently producing 1,700 barrels per day of clean 40 degrees API oil with 10% BS&W, on natural flow.
The company decided to complete the well with an electro-submersible pump, with pump simulation yielding 2,200 barrels per day of production at 40Hz of frequency and bottom hole pressure of
1,710psia.
The Copa-3 is a directional well with 21 degrees of inclination, drilled to a final depth of 5,660ft true vertical depth sub-sea (TVDSS) (5850ft measured depth).
The top of the Carbonera C7 sandstones was found at a depth of 5,165ft TVDSS, with preliminary petrophysical evidence showing 30ft of net pay zone with porosities of 29.5%.
Production tests have shown an initial rate of 1,700 barrels per day of 40 degrees API oil with 10% water cut, on natural flow, with bottom hole pressure of 2,180psia.
The company said that well logs have also shown sand development and high hydrocarbon saturation in the C3 and C5 formations with petrophysical characteristics of 21ft and 35ft, and porosities of 27% and 27.2%, respectively, with a total net oil column of 86ft.
The company’s current exploration portfolio includes four additional prospects (one to the north and three to the south of the Copa-1 discovery accumulation) that are slated to start drilling in the first quarter of 2011.
