Instructor
Dr. Robello Samuel is an internationally recognized drilling engineering expert, educator, inventor, author, and SPE Honorary Member. He has over 40 years of experience in drilling operations, technology development, research, consulting, software innovation, and university teaching and is widely recognized for his significant contributions to drilling engineering and well construction technology.

The Facts, Fallacies, Claims and Pitfalls section can challenge commonly repeated statements such as:
“A packed BHA always holds inclination.”
“A pendulum BHA always drops angle.”
“A near-bit stabilizer always increases build tendency.”
“Three stabilizers automatically produce a stable BHA.”
“More stabilization always produces a smoother hole.”
“A full-gauge stabilizer remains full gauge throughout the run.”
“Standard stabilizer-spacing charts apply to every formation.”
“The planned BHA geometry represents its actual downhole geometry.”
“The same BHA will produce the same directional response in different wells.”
“Is the stabilizer placement guidelines valid for all wells?”
