Job Description

  • Well planning: Trajectory design based on reservoir targets and local constraints;
  • Directional well planning for all anticipated directional wells;
  • Directional Well Planning to include a Geodetic coordinates systems conversion application as well as a Geomatic model updated on a regular basis, i.e. BGGM (to model local Earth Magnetic
  • Field, Dip Angle, and Magnetic Declination);
  • Directional Well Planning to include well positioning uncertainty calculation based on ISCWSA
  • models;
  • Directional Well Planning to include way-to-target functionalities for daily well trajectory followup;

Candidate:

  • To provide directional maps: i.e. Vertical Section view plot, Plane view plot. The vertical directional map will allow projection of the well profile over unwrapped horizontal departure as opposed to a vertical section plan.
  • Trajectory plots on request;
  • Anti-collision calculations with existing wells while designing the trajectory;
  • Prepare spider plots and travelling cylinders with no-go areas;
  • Calculate Non-Magnetic spacing requirements to ensure surveys are within Field Acceptance

Criteria;

  • Select and propose BHAs including BHA tendency analysis;
  • Optimize the position of jars in the BHA with a proper dedicated jar placement software;
  • Perform hydraulic simulations (expected ESD, ECD and SPP). Recommendations on bit nozzle
  • selection or TFA;
  • Run Torque and Drag analysis, including casing, liner and other requirements;
  • Laise with multiple functions to ensure proper fitting between each BHA element (Jars, Reamers, etc.);
  • Technical support and advice to the CLIENT drilling department on the optimum techniques to realize the objectives of the well;
  • Recommend BHAs, drilling assemblies to achieve the desired directional requirements.
  • The recommendation shall include documented analysis of the predicted directional behavior, torque and drag, critical buckling, and hydraulics;
  • Keep survey database up-to-date with the latest drilled wells surveys;
  • Bit TFA calculation for Steerable Motor applications in order to "Thrust Balance" PDM motor bearing assembly for each application as a function of anticipated Flow Rate, Mud Weight and WOB;

Candidate:

  • shall use a BHA tendency predict model for planning, operational, and post-well analysis;

Candidate:

  • shall use a computer model to predict critical harmonic rotary speeds and review results of such predictions with CLIENT and make recommendations to minimize the risks of downhole failures due to harmonic peaks;
  • Recommendations to minimize well tortuosity must be provided;
  • In a collision-risk environment, assist the Directional Driller on the rig site and solely focus on the wellpath realization and projection a minimum of 45 m ahead.

Reporting:

  • Trajectory plots on a daily basis showing realized versus planned trajectory;
  • Validate, QC, and sign off final trajectory;
  • QC data from MWD measurements and gyro measurements, if any;
  • Provide the Directional Drilling Program and End-of-Well Report.
  • Keep track of Lessons learned.
  • Software familiarity:
  • DOX, DrillPlan, Perform Toolkit Pro
  • Compass, WellPlan
  • WellArchitect, JewelSuite Well Engineering

Qualifications

  • University degree in Engineering/related field
  • Experience in the role 5-10 years in onshore /in-house drilling engineering
  • Must hasve the following Software familiarity:
  • DOX, DrillPlan, Perform Toolkit Pro
  • Compass, WellPlan
  • WellArchitect, JewelSuite Well Engineering

Additional Information:

  • The position is open to Nigerian Nationals.
