Predator Oil & Gas (Holdings) plc said it could expand production following excellent results from its pilot CO2 enhanced oil recovery (EOR) in the Inniss-Trinity field onshore Trinidad.
INNISS-TRINITY
The Inniss-Trinity field lies in South Trinidad within the Eastern Venezuelan Basin – one of the largest oil provinces in the world.
The pilot CO2 EOR focuses on a single reservoir sand of the five producing Herrera reservoirs in the field, the Herrera #2 Sand, and a part of the field, the AT-4 block, representing 10% of the total area potentially available for CO2 EOR injection.
PILOT CO2 EOR
From 18 May 2020 to 7 January 2021, Predator injected 443.58 metric tonnes (MT) of CO2 over a planned cumulative period of 45 days.
The company predicts initial results to be at the upper end of the P50 to P10 range (243 to 547 bopd respectively) for the three production monitoring wells included in the forecasts.
The results also showed that CO2 pressure response in five monitoring wells could potentially add three additional production wells to the CO2 EOR expanded programme.
Predator added that the programme had achieved its objectives despite Covid-19, electrical power outages, regulatory delays and well integrity issues in some wells in the AT-4 block which were drilled more than 60 years ago.
FOUNDATION
“The excellent results from the pilot CO2 EOR project, despite a challenging operational environment due to COVID-19, has [sic] de-risked the case for CO2 EOR and established the company as the ground-breaking leader in CO2 EOR expertise and delivery onshore Trinidad and within the wider Caribbean region,” said chief executive Paul Griffith.
“Results more than just support pre-pilot CO2 EOR forecasts and create a solid foundation for expanding production growth over the next twelve months.
“Expanding our successful CO2 EOR business can be achieved by increasing production revenues and also by offering fee-paying services to other operators with profit-sharing entitlements.”
