Drilling Superintendent:
The operating company employee in charge of drilling operations. The drilling superintendent typically works in a field office away from the rig site and supervises simultaneous drilling operations of multiple wells. The rig-site company man reports to the drilling superintendent. From the operating company’s perspective, the drilling superintendent is the principal representative in charge of the safety and environmental aspects of the drilling operations. The position of the drilling superintendent is typically given to experienced drilling engineers.
Wellsite Personnel:
Company Man:
The operating company representative at the rig site. This function is typically handled by an experienced drilling engineer or wellsite geologist who looks after the interests of the operating company. In addition, the company man liaises with the tool pusher to ensure the well plans are carried out to the operating company’s specifications and safety standards.
Wellsite Geologist:
An operating company geologist who reviews the geologic progress of the well as it is being drilled. Typical tasks performed by a wellsite geologist include planning and reviewing well logs during Well Log Operations (well logs are records of geological data versus depth used by geologists to evaluate a well); reviewing Logging while Drilling (LWD) or Measurement while Drilling (MWD) data if available (LWD and MWD are relatively recent developments that include logging equipment on the Bottom-Hole Assembly (BHA) of the drill string and are used to obtain real-time logs of the wellbore.); and Mud Logging (the analysis of rock cuttings as they are brought up-hole by the Drilling Fluid or Drilling Mud. The main roles of the wellsite geologist are to keep the company man and drilling superintendent appraised of the progress of the well (particularly as it approaches the reservoir targets), to inform the driller and company man when important geologic Marker Beds may be encountered so new drill bits or drilling fluids can be made ready, and to provide written reports and records to development geologists to aid in their interpretations of the well and reservoir.
