Underbalanced Drilling

The present crude oil and natural gas reservoirs around the world have depleted conventional production levels. To continue enhancing productivity for the remaining mature reservoirs, drilling decision-makers could no longer rely on traditional balanced or overbalanced methods of drilling. Derived from conventional air drilling, underbalanced drilling is increasingly necessary to meet today’s energy and drilling needs. While more costly and extreme, underbalanced drilling can minimize pressure within the formation, increase drilling rate of penetration, reduce formation damage and lost circulation, making mature reservoirs once again viable and more productive. To further explain this essential drilling procedure, Bill Rehm, an experienced legend in drilling along with his co-editors, has compiled a handbook perfect for the drilling supervisor. Underbalanced Drilling: Limits and Extremes, written under the auspices of the IADC Technical Publications Committee, contain many great features and contributions including: Real case studies shared by major service companies to give the reader guidelines on what might happen in actual operations Questions and answers at the end of the chapters for upcoming engineers to test their knowledge Common procedures, typical and special equipment involved, and most importantly, the limits and challenges that still surround this technology

This concise technical handbook, written to aid drilling engineers and drilling supervisors in underbalanced drilling (UBD) operations, includes detailed calculations. In fact, readers can easily code the mathematical models presented in this book and build their own UBD simulators in spreadsheet programs. Guo and Ghalambor cover much needed information on the applications for drilling water wells, mine boreholes, geotechnical boreholes, and oil and gas recovery wells by providing illustrative examples throughout the text. Further, they include a complete set of engineering charts with a thorough description of theory and principles. Contents: Underbalanced drilling basics Air, gas, mist, and unstable foam drilling Stable foam drilling Aerated liquid drilling Selecting compressor units Field applications Appendices (Required air flow rates for air drilling vertical holes; required gas flow rates for gas drilling vertical holes; required air flow rates for air drilling deviated holes).

The third edition of Air and Gas Drilling Manual describes the basic simulation models for drilling deep wells with air or gas drilling fluids, gasified two-phase drilling fluids, and stable foam drilling fluids. The models are the basis for the development of a systematic method for planning under balanced deep well drilling operations and for monitoring the drilling operation as well as construction project advances. Air and Gas Drilling Manual discusses both oil and natural gas industry applications, and geotechnical (water well, environmental, mining) industry applications. Important well construction and completion issues are discussed for all applications. The engineering analyses techniques are used to develop pre-operations planning methods, troubleshooting operations monitoring techniques and overall operations risk analysis. The essential objective of the book is drilling and well construction cost management control. The book is in both SI and British Imperial units. - Master the air and gas drilling techniques in construction and development of water wells, monitoring wells, geotechnical boreholes, mining operations boreholes and more - 30% of all wells drilled use gas and air, according to the U.S. Department of Energy estimates - Contains basic simulation equations with examples for direct and reverse circulation drilling models and examples for air and gas, gasified fluids, and stable foam drilling models

Written by the Shale Shaker Committee of the American Society of Mechanical Engineers, originally of the American Association of Drilling Engineers, the authors of this book are some of the most well-respected names in the world for drilling. The first edition, Shale Shakers and Drilling Fluid Systems, was only on shale shakers, a very important piece of machinery on a drilling rig that removes drill cuttings. The original book has been much expanded to include many other aspects of drilling solids control, including chapters on drilling fluids, cut-point curves, mud cleaners, and many other pieces of equipment that were not covered in the original book. - Written by a team of more than 20 of the world's foremost drilling experts, from such companies as Shell, Conoco, Amoco, and BP - There has never been a book that pulls together such a vast array of materials and depth of topic coverage in the area of drilling fluids - Covers quickly changing technology that updates the drilling engineer on all of the latest equipment, fluids, and techniques
