Discover why directional drilling is one of the most dynamic and rewarding career paths in the oil and gas industry.
Define directional drilling and explain its purpose across diverse scenarios. Identify well profiles—vertical, J-type, S-type, horizontal—and deflection devices jetting, whiptock, steerable motors, rotary steerable systems.
Learn the directional driller's critical roles in safe, efficient well delivery, from prejob planning, BHA design and makeup, tool gauging, and fishing diagrams, to hsse reporting and safety leadership.
Learn anti-collision for safe well placement. Assess proximity using ellipses of uncertainty and separation factors, and apply 3d least distance, normal plane, and horizontal plane scanning.
Explore drill pipe, drill collar, and heavyweight drill pipe, and their roles in weight on bit, rotation, mud circulation, and basic drill pipe design considerations.
Design and analyze bottom hole assemblies to control direction in directional drilling, leveraging pendulum force, fulcrum and stabilizer placement to build, hold, or drop inclination.
Learn how mud motors convert fluid energy into torque to spin a bit with a rotor and stator; lobe count, stages, and ERT stator shape torque, rpm, heat, and steering.
In this section, you'll find a downloadable BUR Chart, a practical tool designed to support your daily work as a Directional Driller. This chart helps you estimate the build-up rate based on motor size, hole size, and stabilizer setup—making BHA design faster, more accurate, and aligned with your planned trajectory.
Build-Up Rate (BUR) Chart – What It Is and How to Use It
The Build-Up Rate (BUR) Chart, also known as the Motor Output Chart, shows the maximum angle-building capability of a motor BHA when sliding (or orienting). This chart is extremely useful for Directional Drillers to select the right BHA design for a specific well trajectory.
Why Is It Important?
Experienced Directional Drillers with years of fieldwork often develop a sense of how much angle a certain motor BHA can build. They rely on memory and past experience with combinations of:
Bent housing angle
Stabilizer setup
Hole size and bit size
However, this approach only works well with familiar setups.
To reduce guesswork and improve accuracy, the BUR Chart provides a calculated reference based on:
Motor size
Hole size
Number and type of stabilizers (sleeve or string)
Stabilizer size
It gives a more realistic estimation of a BHA's ability to achieve the planned well trajectory and helps avoid designing a BHA that underperforms or fails to meet trajectory requirements.
While not a guarantee of success, this chart has been successfully used across Asia, the Middle East, and Australia, proving to be a practical guide in BHA planning.
What’s in This Book?
This book includes BUR charts for the most commonly used motor sizes in directional drilling:
4.75"
6.5"
6.75"
8.00"
9.625"
Each motor size is further broken down based on:
Hole size
Number of stabilizers
Stabilizer types and sizes
How to Read the Chart
The Y-axis represents the bent angle set on the motor.
The X-axis shows the expected BUR (degrees/30 m).
To find the BUR for a specific bent angle:
Start with your desired bent angle on the Y-axis.
Draw a horizontal line until it intersects the red curve on the chart.
From that point, draw a vertical line down to the X-axis.
The point where it meets the X-axis is your estimated BUR.
This simple process helps Directional Drillers make more informed decisions when designing the BHA to match the planned trajectory.
Master makeup directional BHA assembly, inspecting the bit and mud motor, dressing nozzles for target TFA, and aligning MWD tool face and scribe line for precise directional control.
Learn motor operation in directional drilling with mud motors, kickoff planning, and tool face concepts (mtf, gtf), plus slide calculations and slide sheets for trajectory control.
Monitor downhole drilling parameters and time-based logs, including weight on bit, torque, standpipe pressure, and mud properties, to optimize rate of penetration and detect issues.
Learn how to optimize hole cleaning in vertical and deviated wells by managing annular velocity, mud properties, and pipe rotation to prevent stuck pipe, cutting beds, and erosion.
Explore dog leg severity and its impact on wellbore trajectory, and learn to calculate buildup rate and turn rate, while understanding torque, drag, key seats, and pipe wear.
Explore how mechanical, hydraulic, and hydromechanical jars generate controlled downhole impacts to free stuck pipe, with emphasis on jar placement, weight on bit, pump open force, and neutral point management.
Explore drill bit technology across roller cone and fixed cutter bits, including mil tooth, insert, PDC, and diamond designs, their formation interaction, hydraulics, and selection for efficient drilling.
Assess bit condition for directional drilling by grading inner and outer cutting structures, gauge wear, and dull characteristics to guide future bit selection and drilling performance.
