Early production: converting time into capital.

A barrel produced today is not worth a barrel produced in three years — discounting and project risk see to that. The entire early production facility (EPF) industry rests on that fact: rather than waiting for permanent installations, the well is brought on stream with mobile equipment — separation at the wellhead, tanks on containment, trucking for evacuation — and you sell while you learn. It is the model we detail, unit by unit, in our capture fleet.

Time is the most expensive variable

Between the investment decision and first oil, a conventional development — fixed tanks, a processing centre, a pipeline — takes three to five years. A mobile configuration deploys in six to twelve months, sometimes less when the equipment exists second-hand. On a marginal field, those years of accelerated cash flow often change the sign of the net present value: fields that are “uneconomic” under classic development become financeable under early production. This is especially true of low-rate re-entered wells, where a permanent installation will never be justified.

Separate first: the right crude in the right tank

The link that makes everything else possible is the mobile three-phase separator. At the head of the chain, this containerised skid splits the well effluent into its three components: gas to measurement — and, tomorrow, to use — rather than to the flare; produced water to containment and treatment; and the crude, finally, to the tanks. For Doba’s heavy crudes, a heater-treater breaks the water-in-oil emulsion every well inevitably produces in its early life.

Without this step, the tanks fill with an unsaleable emulsion and you store water at the price of crude. With it, every barrel leaves on commercial specification — basic sediment and water (BS&W) below 0.5% — through custody-grade metering. Recovering the crude starts with separating the right crude.

CAPEX becomes OPEX

Mobile tanks, containerised separators, tanker trailers: everything can be rented, bought second-hand or amortised across successive wells. A heavy, irreversible investment sized on assumptions is replaced by a variable, reversible expense sized on facts. If the well disappoints, the fleet packs up and redeploys — the loss is a few months of rental, not a stranded installation. For a company in formation, it is also the only financeable structure: initial capital needs are divided by five to ten, and each well becomes a self-contained profit centre that funds the next one.

Data paid for by the barrels

Six to twelve months of early production are also an extended well test: pressure, depletion, water breakthrough, GOR — the reservoir’s real behaviour is measured while the crude is being sold. The final development is then calibrated on facts, not on a model: less over-sizing, fewer bad surprises. In practice, the field pays for its own reservoir study.

Early production converts time into capital: first oil ten times sooner, capital five times lighter, self-funded reservoir data. The price: a higher cost per barrel — and a discipline that cannot be improvised.

The limits, faced squarely

The unit cost is higher than a high-throughput permanent installation: trucking costs several dollars per barrel where a pipeline costs less than one. Beyond a sustained volume the advantage reverses — that is the signal to switch to permanent infrastructure. Associated gas demands a plan from day one, or the model falls back into flaring. And fiscal metering of test barrels must be beyond reproach from the first barrel: metrology is the first line of the contract with the State.

Applied to Chad, the model has two amplifiers of its own: local content — building and maintaining the tanks in-country attacks the cost line that usually kills EPFs in landlocked Africa, imported rentals paid in hard currency — and the modular mini-refinery, which gives early crude an outlet a few hundred kilometres away instead of an export haul of a thousand. EnerTchad is a company in formation: this model is our studied entry path, dated in our targets, with its switching thresholds towards permanent infrastructure — not an ongoing operation.
