Accident free drilling
Structure of the service:
1. Preliminary analysis of drilling program and "experience" of neighboring wells. Creation of a report on possible problems and possibilities for their solution, organization of meetings "Drilling on paper".
- Availability of information on previous wells and measures to solve probable problems.
- Construction of the hydraulic model of the well, correction of washing modes based on this model, calculation of the "window" mechanical speed taking into account the geological model and parameters of the pancreas.
- Construction of the hydrodynamic model of the well, selection of the "drilling window".
- Description of the main controversial issues for the organization of the meeting "Drilling on paper".
2. Control of contractors for the construction of a well at the objectivity of current operational information.
- Independent control of the full implementation of specification by the orderly organizations.
- Control of the drilling mud contractor for compliance with planned data quality and quantity of reagents used.
- Control of the geological and technological research service for full compliance with specification, calibration of sensors and gas analysis systems, quality control and quantity of sludge taken.
- Monitoring of bit service and used bits.
- Control of the directional drilling service for the full implementation of specification and the absence of unacceptable deviations of the well trajectory.
- Control of the contractor for drilling for compliance with drilling equipment technical task.
3. Prompt identification of possible geological and technological problems, prompt notification, proposal of countermeasures, "Analysis" of emergency situations.
- Problems of communication between drilling participants.
- Tool grip: Hole Pack-Off / Bridge, differential tack, mechanical stitch.
- Well geometry.
- Instability of the wellbore.
- Loss of circulation.
- Vibration of the drill string.
- Shows of oil-gas and water.
4.Writing a report on the problems during the construction of the well. Description of measures to prevent these problems.
