Responsibilities

• Prepared, assembled and programmed M/LWD tools; ran surface tests before running in hole.
• Made up the BHA: installed M/LWD tools in the drill string and set the tool face offset.
• Rigged up and down surface acquisition systems and sensors: standpipe pressure, depth encoder, hook load.
• Took inclination, depth and azimuth surveys to build 3D wellbore trajectories.
• Worked with directional drillers on directional drilling.
• Monitored drilling parameters: torque, weight on bit, rate of penetration, mud, pressure, vibration, stick-slip.
• Analysed logging and drilling data when problems occurred.
• Passed gamma ray and resistivity data to geologists.
• Acquired data, generated logs, ran quality control and delivered results to the customer.
• Daily reporting: Bursoft (Wellplan), Plotmanager, LAS files, Microsoft Office.
• Kept the equipment inventory and supervised its movement to and from the well site.
