How to increase oil<br />

production<br />

What is the key to reviving crude oil production<br />

in Trinidad and Tobago, which, as already<br />

noted, has crashed from 229,589 b/d 34<br />

years ago to 69,062 b/d today?<br />

But there have been precious few of those by companies<br />

working under the current system of production-sharing<br />

contracts (PSCs).<br />

Companies operating under the older exploration and<br />

production (E&P) licences have been a little more successful.<br />

Bayfield Energy (now absorbed by Trinity Exploration and<br />

Production) has identified what it said were about 32 million<br />

barrels of recoverable oil with its FG8 exploratory well in the<br />

Galeota block off southeast Trinidad, while Petrotrin found<br />

The obvious answer is new discoveries.<br />

Compani<br />

about 48 million barrels of “new hydrocarbon potential” in<br />

the course of a five-well exploration programme in the East<br />

Soldado area, subsequently named Jubilee in honour of the<br />

50th anniversary of the country’s independence. Both finds<br />

were made in 2012. Some new oil was also discovered in the<br />

Cory Moruga block on land in 2010.<br />

Further discoveries may be made in the course of the<br />

extensive exploratory drilling due to take place in the course<br />

of <strong>2013</strong>: among others, by Trinity in the Point Ligoure, Guapo<br />

Bay, Brighton Marine (PGB) block in the Gulf of Paria, and in<br />

the Galeota block; by Niko in the Mayaro/Guayaguayare block,<br />

which runs from the onshore to the offshore in south Trinidad;<br />

and by Parex Resources in the Central Range Shallow and<br />

Deep blocks on land.<br />

Under renewed E&P licences, Petrotrin has to drill four<br />

exploratory wells for Trinmar and two in the North Marine<br />

block. Following the interpretation of its 2012 3D seismic<br />

survey, it will also be doing exploratory drilling on land in late<br />

<strong>2013</strong> and beyond.<br />

Exploratory drilling is risky and results can not be guaranteed,<br />

but development drilling in an already producing location<br />

is of course much less so and can at least replace reserves.<br />

Trinity plans to sink 12 development wells onshore in <strong>2013</strong>,<br />

and 12 in the Galeota block. Lease operators, farmout<br />

operators and incremental production service contractors will<br />

all be doing similar work.<br />

Energy minister Kevin Ramnarine has put great faith<br />

in Petrotrin as being “at the centre of the strategy for oil<br />

Countries<br />

production”, and Trinmar as “at the centre of that centre.”<br />

Concurrent with its exploratory activities in Trinmar, Petrotrin<br />

is reactivating its South West Soldado field, now producing<br />

The energy ministry says it will<br />

offer three land blocks for<br />

exploration this year<br />

about 6,000 b/d, in the belief that it can be boosted to 8,000<br />

b/d by the end of <strong>2013</strong>. Sixty wells which were capped ten<br />

years ago are being gradually returned to production: a few<br />

are already producing again, and the rest will come on line as<br />

they are worked over by a rig hired for that purpose.<br />

New block allocations are an important part of minister<br />

Ramnarine’s oil revival plan. In conjunction with Petrotrin, the<br />

ministry says it will offer three land blocks for exploration this<br />

year. More deep water and some shallow water blocks are also<br />

carded for allocation before the end of <strong>2013</strong>.<br />

New blocks, and exploratory and development drilling<br />

in existing blocks, are all essential, but many analysts<br />

point out that for decades companies have ignored oil that<br />

is known to exist and which could have contributed long ago<br />

to arresting the production decline – both heavy oil and “leftbehind”<br />

medium-gravity crude in reservoirs that have ceased<br />

to produce, or are producing very little.<br />

Geologist Dr Krishna Persad has estimated that there is<br />

probably well over two billion barrels of crude left behind in<br />

reservoirs where natural pressure or even pumping no longer<br />

works. As for heavy oil, minister Ramnarine suggests there are<br />

“seven billion barrels in places like Trinmar and the southern<br />

basin on land.”<br />

Even if the correct figure is only half that or less, it represents<br />

a vast unexploited resource that could help achieve the<br />

country’s oil restoration goals.<br />

The government has offered incentives over the years to<br />

encourage companies to invest in mature marine and land<br />

fields, via a 20% tax credit, and to use enhanced oil recovery<br />

measures for lifting heavy oil. In the current national budget,<br />

it introduced a special supplemental petroleum tax rate of<br />

25% for the development of small discovered oil pools lying<br />

inactive. Deep horizon drilling both on and offshore was<br />

encouraged with the offer of a 40% uplift on exploration costs.<br />

The deep horizon, like the deep water, could be an entirely<br />

new source of crude which the ministry has been urging<br />

companies to target.<br />
