Five packs, one field phase each.
Every field has its age and its urgencies. Five pre-assembled scopes, to refine in the configurator — each pack opens the configurator already set to your phase. (indicative envelopes · company in formation) EnerScope™, EnerBuild™, EnerRun™, EnerRevive™ and EnerClose™ — like EnerCamp™, EnerSupply™ and EnerSkills™ for site support — are trademarks in preparation of EnerTchad S.A.: service scopes at target stage, named so they can be asked for simply.
Exploration & Production · Dedicated mature-fields offer
Mature fields: making the barrel’s second life produce.
Doba has produced since 2003; decline and water (water cut > 85%) are now the basin’s daily reality — yet 2 to 3× the volume already produced still sleeps in place. Our mature-fields service line attacks this dormant resource through five integrated levers. (target offer · company in formation)
An aligned commercial model: on the EOR pilot, payment is tied to the verified additional barrel — the operator pays for the result, not the promise. Discuss a mature field →

Specialised lines
Geoscience, interventions, operations, digital.
Exploration & Production · Geosciences & laboratory
Understanding the reservoir before committing the first franc.
An EOR programme or a marginal-block restart begins in the laboratory, not on site. EnerTchad targets a complete geosciences chain — from the core to the Field Development Plan — carried out in Chad, to de-risk each of the operator’s investment decisions. (ambition · company in formation)
Coring, slabs, porosity-permeability, wettability, saturation — the base data that calibrates models and EOR screening on the Doba and Bongor sandstones.
Deliverables: core report · k/φ curves · petrophysical databasePVT analyses, viscosity of 21-24° API heavy crudes, water-EOR chemistry compatibility (natron, neem, CSS) — a Chadian petroleum laboratory targeted, no more six-week shipments abroad.
Deliverables: PVT report · fluid sheets · compatibility testsLog interpretation, static model, flow simulation, P10/P50/P90 uncertainties — the production forecast that holds up before an investment committee.
Deliverables: static & dynamic model · P10/P50/P90 profilesA phased Field Development Plan (FDP), project economics, a 1P/2P/3P reserves file ready for certification — and for the regulator.
Deliverables: FDP · reserves file · barrel economicsTarget: a marginal-field FDP in 6 to 10 weeks, data and models remaining the operator’s property — contributed to theSector atlas only with their consent.
Exploration & Production · Advanced interventions
The lines that complete the catalogue.
Beyond the twelve intervention lines, four advanced capabilities targeted for wells that demand more — sand, long-duration testing, non-destructive testing, downhole diagnostics.
Screens, packers and gravel pack, chemical consolidation — supply, installation and monitoring: securing production from unconsolidated sandstones without prematurely choking the well.
Mature fields · ageing completionsMulti-rate tests, controlled ramp-up, PLT — quantifying a well’s real potential before committing to full development.
Mobile 3-phase separator · zero flaring targetedUltrasonics, magnetic-particle, dye-penetrant and radiographic testing on wellheads, gathering lines and tanks — the non-destructive testing that extends facility life.
Complements robotic inspection (drones, pigs, crawlers)Memory slickline, pressure-temperature profiles, identifying unwanted water or gas — the diagnosis that precedes every return to production.
The systematic entry point of lift & EOR programmesExploration & Production · Production operations
The field’s operations, held daily.
Between two interventions, a field lives: integrity, chemistry, water, shutdowns. EnerTchad offers these recurring operations as an integrated service — the ones that make the difference between an asset that lasts and an asset that declines.
Wellhead and annulus diagnostics, corrosion-erosion monitoring, barriers and pressure tests: extending well life without compromising safety.
Periodic inspections · integrity filesParaffins, mineral deposits, emulsions, corrosion: injection programmes, flow assurance and laboratory monitoring to keep wells and gathering lines clean.
Local inputs preferred · natron, neemSeparation, treatment and reinjection of produced water — environmental compliance and reservoir pressure maintenance, in a short loop with EOR.
Zero non-compliant discharge targetedPlanned shutdowns, regulatory inspections, restart: planning and work permits to make shutdown days rare and short.

Interoperable with the sector AtlasWhy a Chadian oilfield-services arm
The economic case, and the field notes.
OFS · The economic equation
Why a Chadian oilfield-services company changes the cost of the barrel.
In an oil project, most of a well’s cost goes to services — and in landlocked Chad, every service mobilised from abroad pays twice: the service, then the logistics and the waiting. A task force based at the worksite attacks both terms of the equation.
of a well’s cost typically goes to oilfield services and equipment — that is where the competitiveness of a Chadian barrel is won or lost.
of international mobilisation avoided when the crew, tooling and parts are already in N’Djamena or on the basin — waiting for a tool is often more expensive than the tool.
non-productive time (NPT) shrinks when diagnosis, intervention and spare parts are a few hours of track away — not a charter flight and a border away.
integrated OFS removes cascading margins and interface costs between subcontractors: one contact, one responsibility, one price.
The cost-reduction specialists — because we develop local content.
An intervention base at the worksite, Chadian personnel trained by the academy, inputs sourced in-country — from Kanem natron to cotton cellulose. Every localised link removes freight, foreign currency and weeks of waiting: the same service, delivered at the field, structurally costs less — and the value stays in Chad.
For an E&P operator, it is also local content documented contract by contract under the Chadian Petroleum Code: our procurement policy gives bonus scoring to bids from Chadian-registered companies, sizes lots to stay within reach of local SMEs, and builds HSE and quality capability with Tchaditude — the traceability your compliance teams expect.
Six phases, one point of contact.
Our eight services chain across a well’s whole life — here is who does what, phase by phase.
Studies, dossiers & de-risking
Sector Atlas, registry data, dossier assembly — Advisory & Atlas (EnerConseils).
Sites, wellpads & all-weather access
Earthworks, pads, roads, camps — Site & wellpad construction, before the first metre drilled.
Well testing and bringing on line

Lift, diagnosis, return to production
Wireline, pumps, lift optimisation, wellhead maintenance — the heart of Interventions, backed by the sensors TchadiTech.
Flow, metering, data
Corridor, SCADA, custody metering, digital twins — Logistics & integrity + Technology & data, up to EOR preparation.
Plug & abandonment (P&A)
Cementing, cut and retrieve, site restoration — end of life is part of the contract, not a blind spot.
Specialised “frac tank”-type containers from the moment the well starts up.
From a well’s tests and clean-up flow — even before the permanent facilities — the crude is captured in specialised, adapted containers inspired by frac tanks: high-capacity mobile tanks, set on dedicated containment, connected in series on the wellpad and movable by truck.
A double function: spill protection around operations (containment, confined transfers, nothing on the ground) and immediate commercial recovery — every test barrel is stored, measured and evacuated instead of burnt or lost. The well pays from the day it starts up.
The right tank, at the right well, at the right time.
Six families of mobile containers cover every moment of the well’s life, from the first test barrel to long-distance evacuation — all sit on containment, connect in series and leave by road.
Mobile three-phase separator
The prerequisite of all capture: a containerised skid separates gas, crude and water at the wellhead — a heater-treater (heater-treater) for heavy crudes, metering at the outlet. The crude leaves on spec (BS&W < 0.5%) to the tanks, the water to treatment, the gas is measured instead of flared.
Towable 500 bbl frac tank
The wellpad’s workhorse: a corrugated-wall steel tank on skids, integrated rear axle. Connected in series on containment, opening roof, optional heating coils for paraffinic crudes. Moved empty from well to well.
Road-approved frac tank trailer
Same capacity, mounted as a multi-axle semi-trailer: it captures test crude for weeks on containment, then leaves directly by road for the mini-refinery. Axle load to validate against track conditions.
130 bbl vacuum truck
An onboard vacuum pump: it draws directly from the well cellar, containment bottoms and test tanks, with no external pump. The “zero barrel lost” tool — drips, clean-up flow, loaded fluids. Fast rotation.
Hook-lift skip
A sealed hook tank, set and retrieved in minutes by a standard hook-lift truck: one carrier serves several wells, full skips settle on site. Cut out for marginal wells in re-entry.
26 m³ ISO tank container
A stainless tank in a 20-foot container frame: twist-locks, double valve, flame arrestors. Moves from road chassis to flatbed truck, even to rail — the long-distance evacuation option to the refinery or export.
Towable double-wall tank
A small tank with built-in containment on a light trailer, towable by pick-up and movable full at low speed on the pad. The buffer for the very first barrels of a well test, at the test separator outlet.
A mobile three-phase separator at the head (the right crude on spec, water and gas diverted), two 500 bbl frac tanks connected in series on containment (main storage), a 130 bbl vacuum truck in rotation (active recovery and evacuation), two to three hook-lift skips for satellite wells, a double-wall tank for the initial test phase.
Common specifications: heating coils (paraffinic crudes), vents with flame arrestors, reinforced ground clearance and sand tyres, foldable soft containments that travel with the equipment.
