Sample PEC EPE Petro-Gas Practice Questions

Try these sample questions to test your PEC EPE Petro-Gas exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which theory attributes petroleum primarily to thermal alteration of buried organic matter (kerogen) over geologic time?
A.Inorganic Fischer–Tropsch mantle origin
B.Biogenic/organic kerogen maturation theory
C.Abiogenic asteroid-impact synthesis
D.Cosmic hydrocarbon accretion theory
Explanation: The dominant petroleum geology model is biogenic: kerogen in source rocks matures with burial temperature/time into oil and gas. PEC Breadth explicitly lists theories of origin of petroleum.
2Crude oil is primarily a mixture of which chemical class?
A.Silicates and carbonates
B.Hydrocarbons with minor NSO compounds
C.Pure methane only
D.Metallic oxides
Explanation: Petroleum composition is dominated by hydrocarbons (paraffins, naphthenes, aromatics) plus heteroatom (NSO) compounds. Pure methane describes dry gas, not crude oil.
3An anticline is most important in petroleum geology because it commonly forms a:
A.Source rock kitchen
B.Structural hydrocarbon trap
C.Diagenetic porosity destroyer
D.Primary migration pathway only
Explanation: Anticlines/structural highs are classic structural traps where buoyant hydrocarbons accumulate beneath a seal. Source kitchens and migration are related but distinct concepts.
4Which sedimentary environment is typically associated with high-energy, well-sorted sandstone reservoirs?
A.Deep-marine abyssal clay
B.Fluvial/barrier-bar shoreline sands
C.Evaporitic sabkha anhydrite
D.Lacustrine oil shale only
Explanation: Fluvial channels and barrier-bar shoreline sands often produce well-sorted, high-energy sandstones with good reservoir quality. Abyssal clays and evaporites are typically seals or source/non-reservoir.
5Geothermal gradient typically increases subsurface temperature by about how much per kilometer of depth in many sedimentary basins (order of magnitude)?
A.~1 °C/km
B.~25–30 °C/km
C.~200 °C/km
D.~0.1 °C/km
Explanation: Typical sedimentary-basin geothermal gradients are roughly 25–30 °C/km (varies by heat flow). Extremely low or high values are atypical for normal basins.
6Which reservoir drive mechanism typically yields the highest primary recovery efficiency for oil?
A.Solution-gas (depletion) drive
B.Water drive (strong aquifer)
C.Gravity drainage alone with no pressure support
D.Rock and fluid expansion only
Explanation: Strong water drive often sustains pressure and displaces oil more effectively than pure depletion/solution-gas drive, which usually has low recovery. Gravity drainage can help but alone is not typically highest.
7Seismic reflection surveys primarily map subsurface structure by measuring:
A.Natural gamma radioactivity of shales
B.Two-way travel time of reflected acoustic waves
C.Mud filtrate invasion diameter
D.Capillary pressure curves
Explanation: Reflection seismology records acoustic energy reflected from impedance contrasts; travel time and amplitude map structure and stratigraphy for exploration.
8A good reservoir rock typically requires both storage and flow capacity, expressed mainly as:
A.High TOC and HI only
B.Adequate porosity and permeability
C.High vitrinite reflectance only
D.High acoustic impedance only
Explanation: Reservoir rock characteristics center on porosity (storage) and permeability (flow). TOC/HI and Ro relate to source rocks; impedance is a seismic property.
9In rotary drilling, the primary function of the kelly (or top drive) is to:
A.Measure formation porosity
B.Transmit rotary torque and allow drillstring rotation while circulating
C.Cement the casing shoe
D.Perforate the pay zone
Explanation: The kelly/top drive system rotates the drillstring and permits continuous circulation. Porosity, cementing, and perforating are separate operations.
10Hydrostatic pressure of a 12.0 lb/gal mud column at 10,000 ft true vertical depth is approximately (ppg×0.052×TVD):
A.6,240 psi
B.5,200 psi
C.7,800 psi
D.4,160 psi
Explanation: P = 0.052 × MW × TVD = 0.052 × 12.0 × 10,000 = 6,240 psi. This is the standard field hydrostatic formula.

About the PEC EPE Petro-Gas Exam

The Engineering Practice Examination (EPE) Part-II for Petro-Gas Engineering is PEC’s discipline paper for Registered Engineers seeking Professional Engineer (PE) registration. It is a 3-hour open-book MCQ paper with 60 questions: 25 Breadth items aligned to the undergraduate petro-gas curriculum (geology/geophysics, drilling, well logging, petrophysics, reservoir fluids, reservoir engineering, and production engineering) and 35 Depth items in one opted specialization (Drilling Engineering, Reservoir Engineering, or Production Engineering). Candidates must also pass Part-I (common, 40 MCQs, 2 hours) at 60% independently.

Assessment

Same-day two-part MCQ exam. Part-II Petro-Gas is open-book Breadth (Section A) plus one Depth specialization (Section B: Drilling, Reservoir, or Production Engineering).

PEC EPE Petro-Gas Study Tips from Top Performers

1Map Breadth hours across geology, drilling, logging, petrophysics, fluids, reservoir, and production
2Choose a Depth track that matches your daily practice (Drilling, Reservoir, or Production)
3Build a tabbed open-book kit early—Part-II rewards fast lookups of formulas, charts, and procedures
4Practice timed 60-question sets in three hours to match Part-II pacing
5Drill hydrostatic pressure, Darcy, MBE, IPR, and gas-lift calculations until they are automatic
6Keep Part-I (management, ethics, environment, hazards, communication) warm if attempting both parts the same day
7Confirm cycle dates, centres, and fee voucher rules on cpd.pec.org.pk before applying
