Explore single phase gas reservoirs, seismic mapping of extent and thickness, core data with saturations and porosity, initial gas in place, and gas or water drive with material balance insights.

Explore material balance in a water-drive gas reservoir, calculating initial gas in place, water encroachment and reserves, then estimate cumulative gas production with P over Z and gas equivalents.

this lecture presents chapter four solutions, calculating initial gas in place from pressure and z factor, and applying material balance to gas production, storage, and water influx scenarios.

Explore gas condensate reservoirs and their dew point behavior, where condensate forms in the reservoir until critical saturation and then is produced as surface condensate via a two-stage separator.

Explain gas condensate reservoir behavior under pressure decline and retrograde condensate formation, using a PBT cell experiment to relate volumes, production, and gas composition.

tackle chapter five problems for a gas condensate reservoir, valuing gas and condensate per acre-foot using recovery factors and prices, and compute initial reserves and production forecasts.

Analyze undersaturated oil reservoirs and bubble-point dynamics, where gas comes out of solution and remains immobile until a critical saturation, influencing formation volume factors, gas-oil ratio, and recovery potential.

Predict oil and gas production in undersaturated reservoirs with the material balance equation. Explore bubble point and gas coming out of solution, noting formation and water compressibilities.

Apply material balance to undersaturated reservoirs, compute recovery factors, initial oil in place, gas in solution, and plot recovery versus pressure across bubble point scenarios.

Explore saturated oil reservoirs, gas cap behavior, and how gas expansion drives oil production; analyze phase diagram concepts, gravity segregation, and water drive effects on initial oil in place.

Explore saturated oil reservoir driving mechanisms—depletion drive, gas cap drive, and water drive—and use driver indices, material balance, and fluid property data to estimate oil in place and predict production.

Chapter seven saturated reservoir problem 7.9 guides oil production estimates as pressure drops to 2900 psi using two-phase volume factor and the internal balance equation to obtain MCP.

Explore Darcy's law for single-phase laminar flow in reservoirs, linking permeability, viscosity, and driving force—pressure gradient and gravity—to apparent velocity, with mobility as the key metric.

Analyze time-dependent pressure propagation in a radial reservoir around a central well, applying Darcy's law to incompressible and compressible fluids and deriving pseudo steady state times and permeability estimates.

Analyze chapter eight problem solutions on single-face reservoirs, calculate pressures, flow directions, apparent and actual velocities, and displacement times for oil water systems.

Learn to derive the radial diffusion equation for single-phase flow in reservoirs, apply Darcy's law, and use pressure transient testing to infer reservoir properties.

Explore how applied petroleum reservoir engineering chapter 8b solutions calculate pressure drops using the eeye equation and image wells, apply superposition, and assess drawdown, build-up tests, skin factor, and permeability.

Explore how multiphase flow affects macroscopic and microscopic displacement efficiency, interfacial tension, capillary pressure, wetting, and relative permeability, and why residual saturation limits oil recovery.

Explore fractional flow, water cut, and relative probability ratios, and analyze how mobility, heterogeneity, and sweep efficiency govern oil displacement and gas drive processes.

Apply Darcy's equation to Chapter 10 problems on oil and gas displacement and absolute and relative probabilities. Compute fractional flow, recovery, and permeability considerations across saturations.
