Solve radial-flow problems for oil and gas wells, including skin, partial penetration, and productivity index, and interpret the results physically.

Quantify aquifer support using van Everdingen-Hurst and Fetkovich water-influx models, and compare the resulting OOIP with volumetric estimates.

Forecast production with exponential, hyperbolic, and harmonic decline, estimate EUR, and calculate the economic limit rate.

Explain the functions of rig systems, casing strings, and cement sheath, and estimate pore pressure and fracture gradient from offset data.

Identify the sequence of drilling operations from spud to completion and the documents that record each step.

Design a casing scheme for a vertical well by selecting setting depths from pore-pressure and fracture-gradient plots and checking burst, collapse, and tension.

Calculate mud density windows, equivalent circulating density, and annular pressure losses, and identify the kick-tolerance limit for the planned mud weight.

Evaluate a well-control kick scenario using shut-in drillpipe and casing pressures, and state the correct kill-mud weight and kick volume.

Compare cementing objectives and displacement efficiency for primary cementing and squeeze operations.

Explain directional-drilling survey methods, dogleg severity, and their effect on torque and drag.

Perform nodal analysis from reservoir through tubing and choke to separator, and identify the component limiting well performance.

Select artificial-lift methods for given rate, depth, and fluid conditions, and justify each choice against gas lift, ESP, and rod pump limits.

Calculate skin components and predict production gains from matrix acidizing and hydraulic fracturing using basic geometry models.

Interpret multiphase-flow regime maps and choose an appropriate vertical or horizontal flow correlation with stated validity.

Diagnose sand-production and water-coning risks from completion and production data and propose a control measure.

Calculate gas z-factor, density, viscosity, and compressibility using Standing-Katz and corresponding-states methods, and check against laboratory data.

Apply the real-gas pseudo-pressure form of Darcy's law to gas-well deliverability and compare it with the pressure-squared approximation.

Design a basic gas dehydration and sweetening train by selecting glycol and amine process conditions and sizing key equipment.

Calculate compression horsepower and stage requirements for a given suction and discharge pressure, including interstage cooling.

Size a gas transmission line with the general flow equation and predict hydrate-formation conditions and a prevention method.

Describe the petroleum system elements for a basin and rank source, reservoir, seal, trap, and timing as a prospect risk.

Interpret a provided seismic section by identifying reflectors, faults, and a closure, and convert time to depth with a stated velocity model.

Calculate porosity, water saturation, and shale volume from resistivity, density, neutron, and gamma-ray logs using Archie and shale-volume methods.

Identify lithology and fluid contacts from log crossplots and justify each pick with a second independent curve.

Compute gross and net-to-gross thickness and combine them with area and recovery factor into a volumetric estimate.

Build a discounted cash-flow model for an oil and gas project and compute NPV, IRR, payback, and profit-to-investment ratio under at least two fiscal regimes.

Classify reserves and resources using the PRMS categories and map each category to the cash-flow assumptions used.

Quantify risk with expected monetary value and a decision tree for a drill-or-drop decision, including probability of success and dry-hole cost.

Prepare a project schedule with critical-path logic and identify the top three schedule risks with mitigation actions.

Explain how commodity-price, cost, and schedule uncertainty are combined in a sensitivity or Monte Carlo analysis.

Apply hazard identification, risk assessment, and barrier-management principles to a drilling and production scenario, and rank controls by hierarchy of effectiveness.

Outline environmental controls for produced water, flaring, and drilling waste, and identify the regulatory reporting obligations typically attached to each.

Apply professional-ethics principles to a confidentiality, conflict-of-interest, and data-reporting scenario, and state the correct action.

Complete a timed full-length mock exam and analyze every error by domain, root cause, and corrective action.
