President Energy adds three new wells in Rio Negro, Argentina
President Energy PLC completed and tested natural gas wells EV-1001, EV-1002, and LB-1002 in Las Bases and Estancia Vieja concessions, Rio Negro Province, Argentina.
Well EV-1002 has been successfully completed and tested after perforation of an 8.5-m interval in the Vaca Muerta reservoir. During testing, the well flowed at over 100,000 cu m/d (3.53 MMscfd or 580 boe/d) with an 8-mm choke and a wellhead pressure of 1,750 psi.
Unlike EV-1002, which has original pressure in a virtually undrained fault block, EV-1001 is in a producing block with more pressure depletion. Due to this and reservoir quality, the well was both perforated and fracture treated, requiring longer cleanup time. To assist in the cleanup of the near well bore, a treatment with CO2 is anticipated to take place in the next 21 days.
Combined with LB-1002—the first in the three-well drilling program—aggregate production is expected to reach 170,000 cu m/d (6 MMscfd or 1,000 boe/d). This is in line with expectations and translates into an equivalent 6,000 MMbtu/d.
EV-1002 high wellhead pressure compared to the other EV wells requires balancing production from the field to optimize wells of varying pressure being online simultaneously. Due to high pressure, new wells in the same fault block as EV-1002 are being considered for later this year or the first part of 2022.
