Technical Skill Detail: What You Must Be Able to Do

Process & Equipment Operations

• Start-up/shutdown and steady-state control of:
  • 3-phase separators, heater treaters, electrostatic coalescers (interface control, demulsifier dosage, retention time).
  • Crude stabilization (vapor pressure/TVP control), fuel gas systems, flares/flare pilots, and VRUs.
  • Gas compression trains (antisurge logic, recycle, start permissives), dehydration (glycol/solid bed), and gas sweetening awareness.
  • Produced water treatment (hydrocyclones, IGF/WEMCO cells, nutshell filters) to meet discharge specs.
  • Utility systems: instrument air, nitrogen, seawater/firewater, chemical injection, diesel, power generation awareness.
• Pigging and line-up management, including receiver operations, venting, draining, and gas testing.

Control Room (DCS) & Field Interface

• Read PFDs/P&IDs and cause & effects; understand ESD/HIPPS actions and permissives/inhibits.
• Use historian trends effectively: span/timebase selection, deadband awareness, and correlation checks.
• Alarm management: prioritize high-high trips, stand-downs, and override governance.
• Conduct loop checks with I&E: 4–20 mA verification, range scaling, positioner calibration, and solenoid proof tests.

HSE, PTW, and Emergency Response

• PTW categories, risk assessment, JSA, toolbox talks, LOTO hierarchy, and isolation certificates.
• Gas testing (LEL, O2, H2S) and confined space controls; hot work vs. cold work boundaries.
• Firefighting basics: extinguishing media, foam systems, deluge valves; muster roles and casualty handling awareness.

Mechanical & Instrumentation Fundamentals

• Valves (globe, ball, choke), actuator types, fail-safe positions, and leak tightness classes.
• Rotating equipment checks: suction/discharge pressures, NPSH awareness, seal flush plans, vibration/temperature trends.
• Flow and level measurement: orifice, turbine, Coriolis, DP cells, displacer/radar level; basic density compensation awareness.

Ops Excellence & Digital

• CMMS transactions: notifications, work orders, confirmations, and parts reservations.
• Shift log discipline; override/impairment register management; change management participation.
• Basic Excel or digital logbooks; using templates for mass balance and chemical usage tracking.

Field-Useful Equations and Quick Checks

Use first-principles to validate instruments and guide troubleshooting. Key relationships:

• Mass balance (steady state):

  \( \sum \dot{m}_{\text{in}} = \sum \dot{m}_{\text{out}} \)

• Separator liquid retention time estimate:

  \( t = \dfrac{V_{\text{liquid}}}{Q_{\text{liquid}}} \)

• Bernoulli (incompressible, along a streamline, no losses):

  \( \dfrac{P}{\rho g} + \dfrac{v^2}{2g} + z = \text{constant} \)

• Pressure drop with friction (Darcy–Weisbach):

  \( \Delta P = f \, \dfrac{L}{D} \, \dfrac{\rho v^2}{2} \)

• Pump power (hydraulic):

  \( P_{\text{hyd}} = \rho g Q H \quad \Rightarrow \quad P_{\text{shaft}} = \dfrac{P_{\text{hyd}}}{\eta} \)

• Gas law (real gas):

  \( PV = ZnRT \)

• Water cut and GOR:

  \( \text{Water Cut} = \dfrac{Q_w}{Q_o + Q_w} \times 100\% \quad ; \quad \text{GOR} = \dfrac{Q_g}{Q_o} \)

• Pump affinity (for variable speed checks):

  \( \dfrac{Q_2}{Q_1} = \dfrac{N_2}{N_1}; \quad \dfrac{H_2}{H_1} = \left(\dfrac{N_2}{N_1}\right)^2; \quad \dfrac{P_2}{P_1} = \left(\dfrac{N_2}{N_1}\right)^3 \)

• Level DP in separator (liquid density compensation):

  \( \Delta P = \rho g h \) with correction if gas cap density is non-negligible.

Soft Skills That Differentiate

• Clear radio communication, read-back discipline, and accurate shift handovers.
• Situational awareness and hazard recognition; speak up culture and stop-work authority.
• Calm alarm response; prioritize safeguards, isolate the hazard, then optimize.
• Teamwork across disciplines (I&E, mechanical, marine, drilling during SIMOPS).
• Documentation: concise log entries, deviation records, and incident near-miss reporting.
