✍️ Sample SPE Questions & Answers

1. Under OSHA's Process Safety Management (PSM) standard 29 CFR 1910.119, what is the threshold quantity for flammable liquids and gases that triggers PSM applicability?
10,000 lbs

OSHA PSM triggers for flammable liquids/gases at or above 10,000 lbs when stored above their flashpoint.

2. What is 'lost circulation' in drilling and what material is commonly used to combat it?
Loss of whole mud to the formation through fractures or vugs; combated with lost circulation materials (LCM) such as nut shells or fiber

Lost circulation occurs when drilling fluid flows into highly permeable, fractured, or vugular formations; LCMs plug the loss zones to restore returns.

3. What is the significance of the 'Dykstra-Parsons coefficient' (VDP) in reservoir characterization?
It quantifies vertical permeability heterogeneity; values near 1.0 indicate highly heterogeneous reservoirs

VDP ranges from 0 (homogeneous) to 1 (infinitely heterogeneous) and is derived from the log-normal permeability distribution of core plug data.

4. In a three-phase separator, what force is primarily responsible for separating water from oil?
Gravitational settling due to density difference

Water separates from oil in a three-phase separator mainly by gravity as the denser water phase settles to the bottom.

5. A production platform detects a H2S concentration of 10 ppm in the work area. According to OSHA guidelines, what action is required at this concentration?
Workers must be warned and exposure monitored — this is the ceiling limit

OSHA's ceiling limit for H2S is 20 ppm (with a 50 ppm peak for 10 minutes), and 10 ppm is the NIOSH recommended exposure limit requiring monitoring and warning.

6. What does 'swabbing' refer to in well operations and what hazard does it create?
Pulling the drillstring or tubing too fast, reducing annular pressure below formation pressure and potentially inducing a kick

Swabbing occurs when upward pipe movement creates a piston effect that temporarily reduces hydrostatic pressure, potentially pulling formation fluids into the wellbore.
