According to BHPâs Operational Review for the year ended 30 June 2019, its Hi-Hat 1 New-field wildcat (NFW), Block TDAA 14, was plugged and abandoned (P&A) with hydrocarbons encountered. This discovery alongside Bele-1 and Tuk-1 in the Block 23 (a) have âestablished additional volumes around the Bongos discoveryâ - evaluations are ongoing. According to local sources, BHP plans two-three wells appraisal program in its deep-water blocks: TTDAA 5, TTDAA 14, and 23 (a). Details have not been released. Preliminary estimates of the combined unrisked gas resource potential of the blocks TTDAA 5, TTDAA 6, TTDAA 28 and TTDAA 29 are in the range of 2.4-23.6 Tcf and the unrisked crude oil resources are in the range of 428-4,200 MMbo.  Hi-Hat-1 NFW was spudded on 20 May 2019, in 1,782 m water depth and reach total depth (TD) of 12,480.31 ft (3,804 m). The proposed total depth (PTD) was 3,688 m (12,100 ft) with the main objective in the Pliocene. This is likely to be the appraisal well for Bongos 2 NFW, located in the Trinidad Basin. The well which was plugged and abandoned (P&A), with three gas zones and at least one zone being gas/condensate was spud on 20 July 2018 in 1,910 water depth using the Transocean Drillship, Deepwater Invictus, and it reached total depth (TD) of 5,151 m in October 2018. It replaced Bongos 1 NFW which encountered mechanical problems. The rig was moved to well location on 18 July 2018, and it was expected to stay for approximately 90 days. The operator acquired in 2014 17,700 sq km 3D seismic over seven blocks, included the TTDAA 14. The interest holders are BHP with 70% and the remaining 30% with BP TT. Plans for the well were first reported in late February 2018.    Local sources reported that Deepwater Invictus moved on 20 May 2019 to the Hi Hat 1 from the Tuk 1 NFW well location in the Block 23 (a). The Trinidad and Tobago Marine Advisory Notice announced the arrival of the Deepwater Invictus in late February 2019 for BHPâs three wells program, including the Hi Hat-1.   During the Trinidad and Tobago Energy Conference and Trade Show 2019 in Port of Spain on 5 February 2019, the Minister of Energy and Energy Industries Franklin Khan confirmed a follow-up for BHPâs Bongos 2 NFW.More details were not released     Bongos 2 is part of the second phase objective, to assess the commercial potential of the Magellan play, in the Le Clerc gas discovery. Preliminary estimates of the combined unrisked gas resource potential of the blocks TTDAA 5, TTDAA 6, TTDAA 28 and TTDAA 29 are in the range of 2.4-23.6 Tcf and the unrisked crude oil resources are in the range of 428-4,200 MMbo Local news reported in late December 2017 reported that BHP plans to drill the appraisal well for the Le Clercâs gas discovery, during 1Q/2Q 2018. The partners in the block, expect to produce gas from the well around 2026.       On      17 April 2014 BP farmed out a majority interest to BHP Billiton in blocks      TTDAA 14 and 23(a). BP      was awarded on 25 July 2011 production sharing contracts, 100% interest on      both.      Background Information    As of early October 2017, BHP is still interpreting the acquired 17,700 sq km of 3D seismic shot over seven blocks located in the Columbus Basin, as previously reported in late May 2015. The expected processing completion date was March 2016. The acquisition conducted by PGS began in Mid-March 2014 and it is estimated that it was completed in mid-November 2014.
