British oil major, BP said it has made two significant gas discoveries with the Savannah and Macadamia exploration wells, offshore Trinidad.
BP said in a statement that the results of these wells have unlocked approximately 2 trillion cubic feet (tcf) of gas in place to underpin new developments in these areas.
The Savannah exploration well was drilled into an untested fault block east of the Juniper field in water depths of over 500 feet, approximately 80 kilometres off the south-east coast of Trinidad. The well was drilled using a semi-submersible rig and penetrated hydrocarbon-bearing reservoirs in two main intervals with approximately 650 feet net pay. Based on the success of the Savannah well, bpTT expects to develop these reservoirs via future tieback to the Juniper platform that is due to come online mid-2017.
The Macadamia well was drilled to test exploration and appraisal segments below the existing SEQB discovery which sits 10 kilometres south of the producing Cashima field. The well penetrated hydrocarbon-bearing reservoirs in seven intervals with approximately 600 feet net pay. Combined with the shallow SEQB gas reservoirs, the Macadamia discovery is expected to support a new platform within the post-2020 timeframe.
“This is exciting news for both bpTT and the industry, as these discoveries are the start of a rejuvenated exploration program on the Trinidad shelf,” said Norman Christie, Regional President for bpTT. “We are starting to see the benefits of the significant investment we have made in seismic processing and Ocean Bottom Seismic acquisition. Savannah and Macadamia demonstrate that with the right technology we can continue to uncover the full potential of the Columbus Basin. This is a testament to bpTT’s ongoing commitment to the development of our Trinidad and Tobago operations and the wider industry, and we look forward to the future portfolio drill-out.”
