Training Course: Best Practices of Advanced Drilling

Introduction

This training course provides all the fundamentals necessary to drill a well whether it is a shallow well or a complex, high pressure well. It is also designed for engineers and field personnel involved in the planning and implementation of drilling programs.
This covers all aspects of drilling technology, emphasizing both theory and practical application.

This training course builds a firm foundation in the principles and practices of drilling and well planning, drilling fluid, drill string design, hydraulic optimization and drilling hole problems. Participants will learn the components of drilling string and how to use each in optimum ways, how to evaluate the WOB and select the proper size of drill collar. Participants will also be able to apply the practical solution for analyzing the performance of drill string design for both vertical and direction holes.

Course Objectives

• Drill a well cost effectively and maximize penetration rate & Evaluate stuck pipe problems and avoid potential problems by optimizing hole cleaning and ROP.
• Design, drill string and BOP / wellheads & Design and implement bit and hydraulics programs.
• BHA design for proper deviation, directional and horizontal drilling control & recognize and evaluate well control problems by effectively using Mud Logging principles and techniques.
