Petroleum Engineering
An intuitive, interactive Petroleum Engineering course covering the core upstream sequence of a petroleum-engineering program: the petroleum system, rock and fluid properties, formation evaluation, drilling and completions, reservoir engineering, and production. Every lesson pairs plain-language explanations with precise diagrams, worked examples, hands-on simulations, and practice you can check yourself.

The Petroleum System & Industry Overview
How hydrocarbons form, migrate, and get trapped — and the upstream/midstream/downstream industry and units that frame the whole discipline.
Petroleum Geology for Engineers
Just enough geology for an engineer: where reservoirs form, how they trap hydrocarbons, and what makes a play conventional or unconventional.
Rock Properties (Petrophysics I)
The reservoir-rock properties every calculation downstream depends on: porosity, permeability, saturation, and how we measure them.
Reservoir Fluid Properties (PVT)
Phase behaviour and the PVT properties — Bo, Rs, Bg, z-factor, viscosity — that turn subsurface volumes into surface barrels.
Formation Evaluation & Well Logging
FLAGSHIP — reading a well from its logs: gamma ray, resistivity and Archie's equation, porosity logs, crossplots, and an end-to-end interpretation workflow.
Multiphase Flow in Porous Media
When oil, water, and gas share the pore space: wettability, capillary pressure, relative permeability, and a first look at Buckley–Leverett.
Drilling Engineering
Building the well: rig systems, drill string and bits, drilling hydraulics and fluids, directional drilling, and the geomechanical pressure window.

Casing, Cementing, Completion & Stimulation
Turning a hole into a producing well: casing design loads, cementing principles, completion types, sand control, and hydraulic-fracture stimulation.
Reservoir Engineering I: Material Balance & Drive Mechanisms
FLAGSHIP — how much is down there and how it gives it up: volumetric OOIP/OGIP, the material-balance equation, and the reservoir drive mechanisms.
Reservoir Engineering II: Well Inflow & Transient Flow
How fast the well flows: radial inflow, skin and damage, the IPR, the diffusivity equation, pressure-transient analysis, and a look at numerical simulation.

Reserves, Economics, EOR & Capstone
Forecasting and the field's future: decline-curve analysis, the reserves taxonomy, EOR and waterflooding, simple economics, and a full-field capstone.
