Oil & Gas Drilling Best Practices and BHA Design

Introduction:

Today's drilling personnel must know all the required disciplines to drill a well effectively. This oil and gas drilling best practices and BHA design course provides all the fundamentals for drilling a well, whether shallow, complex, or high-pressure.

This oil and gas drilling best practices and BHA design course is also designed for engineers and field personnel planning and implementing drilling programs. It covers all aspects of drilling technology, emphasizing theory and practical application.

Computer programs are used to design many aspects of modern wells, and the course will provide the participants with the theory behind most programs and practical implementation. It will also include advanced Mud Logging principles and operations.

This oil and gas drilling best practices and BHA design training course builds a firm foundation in the principles and practices of drilling, oil, and gas well planning, drilling fluid, drill string design, hydraulic optimization, and drilling hole problems.

Participants will learn the components of the drilling string and how to use each in optimum ways, evaluate the WOB, and select the proper size of the drill collar. They will also be able to apply practical solutions for analyzing the performance of drill string design for both vertical and direction holes.
