Course objectives: The aim of the course is to enable students to appraise the condition in oil, gas and water reservoirs and the reasons that can lead to the kick of formation fluids into the wellbore during drilling. Gaining knowledge about well killing procedures depending on formation properties, position of the drilling tool in the well and other important indicators for applying the appropriate killing method. Acquisition of a routine for calculating kill sheets in accordance with the requirements of the International Well Control Forum with the corresponding calculations. Technical characteristics and operational capabilities of blowout prevention equipment and BOP hydraulic control unit.
- Rock and reservoir properties;
- Wellbore conditions and early signs of kick; kick indicators;
- Slow circulation rate; killing procedures;
- Driller´s method of killing the well;
- Wait and weight method;
- Concurrent method; volumetric method, top-kill method;
- Other killing methods (low choke pressure method, bullheading;
- Kill sheet; principles of blowout simulators;
- Blowout hydraulic control unit (“Koomey”);
- Theoretical basis for calculating the required volume of hydraulic fluid;
- Blowout preventers;
- Final written test in accordance with the rules of the International well control forum.
Learning outcomes at the level of the course:
- Analyze the reasons for kicks and consequent conditions in the wellbore;
- Assess and prepare all calculations necessary for applying basic killing methods, according to the rules of relevant international institutions (IWCF, IADC);
- Recommend the necessary equipment used to prevent blowouts;
- Compare the basic principles of work on simulators;
- Assess all the problems encountered during drilling and choose the most favorable ways of remediation.
