Thanks for that link BDT, there's a lot of info on that site incl below ....
History of CO2 injection in Trinidad and Tobago
Trinidad and Tobago has been involved in the oil and gas industry for over a century. Our daily oil production has been declining since our peak in 1978 and our fields are now classified as mature. Many methods of Enhanced Oil Recovery have been attempted in Trinidad, including the injection of CO2. It was first tested in 1972 by Texaco in Guayaguayare and Brighton which then ramped up in 1974 in the Forest Reserve field. From 1975 to 2004, carbon dioxide was intermittently injected in the Upper Forest Formation and Upper Cruse Sands in the Forest Reserve field. From 1990 to 2000 CO2 was continuously injected in the Oropouche field. Approximately 1.26 million Metric Tons (24 Billion cubic feet) of CO2 were injected in both fields in total to recover 4 million barrels of oil, with a peak production of 812 bopd in Forest Reserve. A positive response to injection was observed in all projects within 6 months to 1 year of CO2 injection. (Mohammed-Singh , 2004) before Petrotrin permanently halted injection in 2004 after an explosion at the Point Lisas compressor station. In 2009, Krishna Persad and Associates (KPA) operated a small, 4 well, pilot CO2 project in the Barrackpore farmout, with quite modest results (Sinanan, B. 2016). Since the KPA pilot ended in 2010 no further CO2 injection occurred until May 2020 at a small pilot project operated by Columbus Energy in the Inniss-Trinity IPSC (Guayaguayare). As of December 2020, a positive response was observed while 70% of the 9 Metric tons/day of CO2 currently being continuously injected is forecast to be sequestered in the Herrera Sands. Future Inniss-Trinity expansion projects have the potential for additional recovery of up to 9 million barrels of oil.
