Our Assets – Onshore
Trinity has been operating and producing onshore in Trinidad since 2007 and holds 100% operated working interest across all of its onshore assets by way of six Lease Operatorship Agreements (LOAs) and the Tabaquite Farmout Agreement within the southern basin and central range.

Current onshore production is from Lease Operatorship Blocks: FZ-2, WD-2, WD-5/6, WD-13, WD-14 and Farmout Block, Tabaquite.
Average 2020 net production from the onshore assets was 1,793 bopd (an 11% increase from 2019: 1,613 bopd), which accounted for 56% of the total annual average production. This significant growth in the year on year production is a direct result of the performance of the 2020 RCP campaign, reduced downtimes facilitated by more-active well management, improved swabbing, reactivations and numerous other production initiatives undertaken in the year.
In 2020, production continued to benefit from the contribution of the 2018/19 infill drilling programme. Furthermore, Trinity has developed a tactical multi-disciplinary team to manage the delivery of these development wells, using best in class models, which in turn helps to ensure they deliver the best economic returns. As such, best in class models were developed to economically maximise well deliverability. This would have pointed to the execution of two RCPs which yielded positive results, enhancing the team’s confidence in the productivity of the Lower Forest sands.
Trinity executed 16 RCPs Onshore during 2020 (2019: 22) as well as 94 WOs (2019: 104). This intensive work campaign successfully maintained base production and provides a stable platform for future production growth. The continued reduction in WO frequency is a testament to the teams drive to reduce pump failure frequency and optimise operating efficiency.
During 2020 and 2021 the team have particularly targeted the stabilisation and optimisation of its largest onshore field, WD-5/6 Block. Focus teams were established to ensure quicker responses to offline wells and drive the redesign of operating thresholds to combat declines.
In 2021, the team has undertaken further cost-effective means of production maintenance through the expansion of the active well stock via RCPs, reactivations and swabbing. Furthermore, the automation roll-out is moving ahead at pace and we remain on target to have 31 new Tier-1 well systems in place by during 2021.
Automation: A key aspect of our well management system
The positive results recorded to date provides confidence in being able to deliver our objectives for the WD-5/6 Block:
- to stabilise 85% of the Block’s production via increased well uptimes.
- to reduce the number of WOs
- by employing 24/7 remote well surveillance.
- to build capacity through increased operational field efficiencies and productivity.
- to reduce the carbon footprint with less workovers and wellsite visits.
- to manage well performance with the use of real time data.
The use of Weatherford’s Foresite Well Optimization platform will support our well management system to manage wells by exception, remotely optimise well performance, and to alert teams for earlier well responses and avert possible premature well failures.
Preparations for the execution of our next infill development campaign are underway. We expect to drill a combination of vertical and horizontal wells, with the timings and location selection dependent on the findings of the on-going 3D seismic data review across our onshore acreage.
New sub-surface models – building low risk exploration & development inventory with best in class partnerships
With the 3D seismic data (37km2) now acquired we have accelerated its integration and interpretation to:
- high grade current drilling locations (HAW/horizontal candidates/well trajectories =>higher IP’s and reserves/well).
- to look at enhanced oil recovery projects.
- to generate new appraisal/ exploration prospects.
This is the first time high quality 3D seismic data has been utilised by a lease operator in this area. The analysis will enable Trinity to redefine basin fill & deformation (stratigraphy & structure) as well as assisting the development of new plays at a local and regional level. As well as targeting deeper (traditional) targets, two teams are working to accelerate the data interpretation of non-traditional plays and targets.
