Underbalanced Drilling (digital Edition) Deepak M. Gala, Steve Nas

Your own body's inner wisdom holds the secret of perfect health, teaches Deepak Chopra, M.D. "On the molecular and cellular levels, the body that you had four years ago no longer exists," teaches Dr. Deepak Chopra. "It has been entirely replaced, atom by atom." Given this fact, could it be that the core of who you are – and your health – lies beyond the material body?

This is the exercise book accompanying Pressure Control During Drilling

Porous sedimentary formations penetrated by the rock bit contain fluids such as oil, gas or salt water. If the hydrostatic pressure of the drilling fluid drops below the formation pore pressure, pore fluid will enter the well and “kick” the mud out of the well. To control the pressure while drilling you need to understand the behavior of gas. This book aims at explaining the physics and the engineering approaches behind pressures in the sediments, detection of unstable wellbores, equipments necessary to close and kill the well, killing methods and offshore challenges.

Fundamentals of Digital Logic and Microcomputer Design, has long been hailed for its clear and simple presentation of the principles and basic tools required to design typical digital systems such as microcomputers.

Progressive in content and form, this practical book successfully bridges the gap between the circuit perspective and system perspective of digital integrated circuit design. Digital Integrated Circuits maintains a consistent, logical flow of subject matter throughout. Addresses today's most significant and compelling industry topics, including: the impact of interconnect, design for low power, issues in timing and clocking, design methodologies, and the tremendous effect of design automation on the digital design perspective. For readers interested in digital circuit design.
