Engineering and technological support for killing a new wellbore from an open wellbore

Main steps:

1. Selection of the necessary equipment, taking into account the design of the well and geological features of the open hole (type of rocks, the presence of caverns, etc.).

2. Preparation and coordination with the Customer of the Plan-program, with a description of all the work, indicating the actual and design data, intervals, geometric dimensions of the layout elements, operation modes, etc.

3. Delivery of the necessary set of equipment.

4. The implementation of engineering and technological services, which includes the following operations:

• Control during the preparation of the wellbore, if necessary;
• Instructions to the Customer’s engineering and drill crew;
• Assembly of the cemented deflector wedge;
• Assembly assembly with a wedge and drain device;
• Unloading the wedge at the bottom in a cement bath installed through it;
• Assembly assembly for cutting a new barrel (rotary or turbine with a rock cutting tool of the Customer);
• Drilling a cement bridge and cutting a new trunk with the study of this interval.

5. Signing of acts, drawing up reports and recommendations.

The entire technological staff performing ITS has a higher specialized education, extensive work experience and all the necessary documents for carrying out work on the well.
