From the tubing wall to the deepwater riser, chemistry decides whether a well keeps flowing. This course works through the corrosion, souring, scale, organic and hydrate threats that attack the production system, and how each one is predicted and managed.
Refined over 15 years of classroom delivery to national and international operators, now rebuilt as a problem-based, self-contained online programme for working petroleum engineers.
Production chemistry is where deliverability quietly erodes. Course 04 trains you to anticipate each threat before it bites, read the early symptoms, and choose the right prevention or treatment.
Tell sweet from sour attack, anticipate chloride and sulphide cracking, and match metallurgy.
Recognise sulphate-reducing bacteria, reservoir souring and biological fouling, and their controls.
Predict soluble and insoluble scale, paraffin wax and asphaltene build-up before they choke flow.
Read formation envelopes, find the vulnerable locations, and design prevention and mitigation.
Metal loss, microbes, mineral scale, organic deposits and hydrate plugs: each appears as conditions change from hot downhole to cold subsea. Every module isolates one threat and the chemistry behind it.
Why steel fails downhole, the prerequisites, the acid gases, and the cracking that follows.
Life in the reservoir: bacteria that sour the fluids and foul the system.
When dissolved minerals fall out of solution and armour the flow path.
When the oil itself deposits, paraffins on cooling, asphaltenes on pressure change.
Ice that isn't cold: where hydrates form, where they threaten, and how to stop them.
Every module opens with a real well problem. You work the engineering, then the theory is introduced to explain what you found: the way the material was honed in the classroom over fifteen years.
Each topic is anchored to a field scenario with real data, not an abstract derivation.
You read the symptoms, identify the threat and quantify the risk, then the theory frames why.
The chemistry here underpins the surveillance, prevention and remediation courses ahead.
Run Course 04 as a pilot for a cohort, or licence the full eleven-course programme. We'll tailor the rollout around your assets and engineering levels.
