Drilling Engineer
Designs and oversees well drilling programs in unconventional formations. High technical and operational pressure in the field.
What does a Drilling Engineer do?
- Develops the program for each well: trajectory, fluids, casing design, cementing, and budget
- Monitors the operation daily from base or on location and compares actual progress against the plan
- Analyzes drilling reports looking for early risk trends such as torque increases or lost circulation
- Approves or rejects program changes proposed by the company man and service companies
- Conducts post-well analysis and carries lessons learned into the design of subsequent wells
- Technically evaluates proposals from directional drilling, fluids, and cementing providers
Ideal OCEAN+ Profile
Ability to solve drilling problems in real time with technical creativity in the face of unforeseen subsurface conditions
Precision in designing drilling programs, fluid selection, casing design, and well control management under API standards
Ongoing coordination with drilling crews, service providers, and field personnel during 24/7 operations
Effective work with the tool pusher, fluids company, site geologists, and directional drilling service providers
Handling well emergencies (kicks, blowouts, stuck pipe) calmly and decisively under extreme, real-time pressure
Drilling operations run on detailed drilling programs, well engineering protocols, and well control procedures that leave no room for improvisation; a Drilling Engineer who deviates from the program without authorization puts well integrity at risk
Strengths and Red Flags
Strengths
- Comprehensive drilling program design with geomechanical risk analysis
- Well control management and emergency response in the field
- Optimization of drilling parameters to reduce days and cost per well
- Technical oversight of completion and cementing operations
Red Flags
- Underestimates early well control indicators due to pressure to keep drilling
- Poor well program documentation that hinders real-time decision-making
- Excessive reliance on providers without active technical oversight of operations
- Rigidity around the original program when subsurface conditions require immediate redesign
What does a successful Drilling Engineer do?
The behaviors that separate top performers from average in this role, and the OCEAN+ profile dimension that explains them.
Orders the well shut in at the first signs of influx without waiting for additional confirmation, and only analyzes afterward whether the signal was real
Emotional StabilityThe high Emotional Stability range reverses the natural bias under pressure: in well control, a false positive costs hours, but a false negative costs the well
Logs every operational decision on the well with its rationale in the daily report, so the next shift inherits context, not just instructions
ConscientiousnessThe Conscientiousness in this range treats the well log as the team's operational memory, not a formality completed at the end of the shift
Routes even minor parameter adjustments through the formal approval process, even ones other crews would settle verbally
Structure & RhythmThe high Structure & Rhythm in this profile knows that serious incidents rarely start with one big deviation: they start with a chain of accumulated informal adjustments
Studies problem wells from the previous campaign before designing the next one, looking for the pattern behind repeated events
OpennessThe moderate Openness in this range is oriented toward solving concrete problems, not experimenting for its own sake: it learns backward to design forward
Listens to the report from the most experienced driller before dismissing a concern that sensors haven't yet confirmed
AgreeablenessThe moderate Agreeableness in this profile makes room for field experience without ceding the technical decision, a balance that reduces blind spots in the operation
Requirements and Skills
- Degree in Petroleum Engineering, Mechanical Engineering, or related field with training in well drilling
- Field drilling operations experience, ideally with exposure to horizontal wells
- Current industry-recognized well control certification
- Proficiency with well design and drilling engineering software
- Availability for field rotation schedules and on-call support for continuous operations
- Working English to coordinate with contractors and read documentation from international suppliers

Anticipating geomechanical risk zones to prevent well control incidents during a campaign
An O&G operator uses this profile to select Drilling Engineers who combine rigor in design with operational calm to make real-time decisions. For example: an engineer designs and oversees a horizontal well campaign with detailed geomechanical risk analysis. Their Conscientiousness allows them to anticipate abnormal pressure zones across several wells, avoiding potential well control incidents. Their Emotional Stability is critical for calmly handling tight hole and stuck pipe events that require real-time redesign decisions. The campaign ends with a reduced cost per well relative to the previous benchmark. This pattern illustrates that the safest, most efficient wells are the ones where risk was mapped before drilling ever began.
