The Well Planner Trajectory Designer will be responsible for designing and maintaining directional and horizontal well trajectories, performing anti-collision analysis, managing survey requirements, and supporting high-volume well planning activities. The role requires strong expertise in wellbore positioning, trajectory optimization, survey QA/QC, and drillability assessment, while working closely with Drilling Engineering, Subsurface, Survey, and Directional Drilling teams.

Key Responsibilities

Design horizontal and directional well trajectories, including build-and-hold, S-curve, modified-S, and catenary profiles.

Calculate and optimize build/drop/turn rates, dogleg severity, landing geometry, and lateral placement.

Perform anti-collision analysis using ISCWSA error models, Separation Factor (SF), Ellipse of Uncertainty (EOU), and closest-approach assessments.

Develop survey programs and perform survey QA/QC, including Multi-Station Analysis (MSA).

Evaluate requirements for geomagnetic corrections and gyroscopic surveys.

Update trajectories based on geological target changes, drilling constraints, and anti-collision risks.

Support trajectory drillability assessment using torque, drag, hydraulics, casing wear, and BHA considerations.

Maintain validated definitive surveys and offset-well information.

Prepare trajectory, survey, anti-collision, and engineering handover packages.

Manage multiple concurrent well plans in multi-well pad, high-volume drilling environments.





Maintain plan version control and engineering documentation.

Technical Skills Tools

Landmark COMPASS or equivalent well planning anti-collision software.

KM ERA or equivalent well engineering tools.

Landmark WellPlan or equivalent torque, drag, hydraulics applications.

Strong knowledge of ISCWSA error models and wellbore positioning.

Understanding of Minimum Curvature Method, DLS, Separation Factor, EOU, MWD surveys, gyro surveys, and survey uncertainty.

Excel, Power BI, Spotfire, and document-management tools.

Python/VBA automation experience is an advantage.

Qualifications Experience

Bachelor's degree in Petroleum, Mechanical, Geosciences, or a related technical discipline.

7 years of experience in well planning, trajectory design, directional drilling, or wellbore positioning.

Hands-on experience designing horizontal and directional wells.

Experience with anti-collision analysis and survey management.

Experience supporting multi-well pad or high-volume drilling programs preferred.

Field exposure to directional drilling, MWD/LWD, BHA behavior, and survey operations is desirable.

Strong analytical, technical documentation, and communication skills.
