The Jacobin well is drilling to a total depth of 9,800 feet and is the deepest well drilled in the area for over a decade.
For the first 5,500 feet or so it will go through some of the most prolific oil producing land in Trinidad. As a consequence, James Menzies was able to say yesterday that the well will find oil, but Trinity isn’t targeting oil in the first 5,500 feet (they’re already producing oil at that level from other wells).
Rather they’re targeting three deeper levels. The first target reservoir, T6, is just over 6,500 feet deep. The second target, T7, is almost 7,500 feet deep. The third, T8, is about 9,000 feet deep.
In other words, there’s almost a quarter of a mile in distance between the existing producing oil reservoir and T6, and then almost another quarter of a mile to T7, and then another quarter of a mile to T8. These reservoirs have developed and, hopefully, filled with oil over millions of years. The presence or absence of oil in any one reservoir is unlikely to meaningfully increase or decrease the prospect of it being in another. Were it otherwise the chance of success in T6 would likely be much higher given that it sits under a known oil reservoir.
Rather Trinity has assessed and published the chances of success of finding oil at each of the three levels they’re exploring, and then using quite proper probability calculations provided an estimate of the chances of at least one of the three reservoirs containing oil. Those assertions have been backed up by the competent person and are in turn backed up by a Technical Committee that consists of Mr Menzies (a geologist, non-executive director of Trinity, and the founder/former CEO of Salamander Energy), Derek Hudson (a geologist, non-executive director of Trinity, and Shell’s former Vice President and Country Chairman of it’s operations in Trinidad) and “three other independent experts who bring complementary and relevant expertise” to the deliberations (see page 36 of https://trinityexploration.com/wp-content/uploads/2023/06/Trinity-EP-2022-Annual-Report.pdf). It’s unlikely that any other smallish energy company has more rigorous oversight of its drilling plans and it’s an approach that has led to considerable refinement of Trinity’s drilling plans.
It’s also worth remembering that Jacobin is about more than finding oil on this occasion. It’s the first of nine deep wells and, if no oil is found, it will likely provide useful information that will assist the rest of the campaign.
In any event, it’s not long to wait now until we find out what Jacobin has discovered - the report is due by about mid-July (although Mr Menzies cautioned yesterday that “God laughs at oil drillers timescales”).
