As a well draws down, the fluids around it begin to move, and water or gas can cone toward the perforations long before the reservoir is swept. This course covers the physics of fluid interfaces, the principles of coning and cusping, how breakthrough is diagnosed, and how it is prevented and remediated.
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.
Coning rarely arrives without warning. Course 05 trains you to read the interface physics, estimate the rate that keeps a cone stable, confirm a breakthrough's true cause, and choose the remedy that buys the most time.
Work with fractional flow, displacement stability and the onset of viscous fingering.
Tell stable cones from unstable ones and estimate the critical rate, including anisotropy effects.
Separate mechanical failure from genuine reservoir dynamics with production logging and testing.
Apply standoff, rate management, recompletions and stimulation to keep unwanted fluids out.
Interfaces move, cones form, fluids break through, and engineers respond. Each module follows that arc, the physics first, then the diagnosis, then the response.
How contacts move and fronts (de)stabilise: the displacement physics behind everything that follows.
When drawdown pulls water or gas toward the perforations, and the rate that keeps it at bay.
Telling a real cone from a casing leak, and the logs that prove which it is.
Buying time and recovering it: standoff, rate management, barriers and stimulation.
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 trace the rising fluid to its cause and quantify the rate that controls it, then the theory frames why.
The dynamics here set up the surveillance and remediation courses that follow.
Run Course 05 as a pilot for a cohort, or licence the full eleven-course programme. We'll tailor the rollout around your assets and engineering levels.
