Effective Methods Of CBM Drilling & Completion

 

CBM Drilling and Completion methods of successful coal seam methane projects vary widely. It is important to understand the pros and cons of the different techniques in order to select the best procedures. This course discusses how to drill and complete CBM wells.

 

Specific topics to be covered

 

- Basics of a Successful Gas Drainage or Production Drilling Program

 

- Well Planning

 

- Suitable Rigs

 

- Drilling Practices

 

- Vertical Drilling

 

- Horizontal Directional Drilling

 

- Lateral and Multilateral Drilling

 

- Completion Types and Design

 

- Completion Treatments (Job Pumping)

 

- How to apply these Technologies Including Recent Case Studies on How Horizontal/Directional Drilling has Improved Production Potential
