Book Description
This Field Operations Manual provides drilling engineers a means of making quick, graphical determinations of gas (air) and liquid volumetric requirements in air, foam, and mist drilling. A model for predicting correct air (gas) volume requirements in air drilling has been developed. It includes a complete analysis of pressures throughout the system, offers flexibility in selection of wellhead pressure and air flow rate, and is primarily graphical. Charts are presented for sandstone, shale and limestone formations. A model has also been developed for predicting minimum volumetric requirements for foam and mist drilling operations. It accounts for frictional losses due to the solid-phase, pressure drop across bit nozzles and particle settling velocities. The technique offers a high degree of flexibility in the selection of wellhead injection pressures and volumetric requirements. Actual field application of this work can be accomplished by two different methods depending on compressor specifications. These are the Variable Back pressure and Constant Back Pressure schedules. They are primarily graphical. The main advantage of these techniques over the currently practiced trial and error methods in aerated drilling is the prevention of the use of excess air (gas) and/or foamer solution while the hole is still in gauge. If these results can be realized, problems such as hole enlargement, sloughing shale, and wellbore collapse can be minimized and drilling costs will be reduced. All of the charts presented in this manual assume regular bits with nozzles of 28/32 inches each. For large bit nozzle sizes used in aerated drilling, pressure drop across such nozzles is negligible in comparison to total system losses. Thus the charts are also applicable to conditions where no nozzles are involved.

Book Description
Working Guide to Drilling Equipment and Operations offers a practical guide to drilling technologies and procedures. The book begins by introducing basic concepts such as the functions of drilling muds; types of drilling fluids; testing of drilling systems; and completion and workover fluids. This is followed by discussions of the composition of the drill string; air and gas drilling operations; and directional drilling. The book identifies the factors that should be considered for optimized drilling operations: health, safety, and environment; production capability; and drilling implementation. It explains how to control well pressure. It details the process of fishing, i.e. removal of a fish (part of the drill string that separates from the upper remaining portion of the drill string) or junk (small items of non-drillable metals) from the borehole. The remaining chapters cover the different types of casing and casing string design; well cementing; the proper design of tubing; and the environmental aspects of drilling.

Book Description
Petroleum engineering now has its own true classic handbook that reflects the profession's status as a mature major engineering discipline. Formerly titled the Practical Petroleum Engineer's Handbook, by Joseph Zaba and W.T. Doherty (editors), this new, completely updated two-volume set is expanded and revised to give petroleum engineers a comprehensive source of industry standards and engineering practices. It is packed with the key, practical information and data that petroleum engineers rely upon daily. The result of a fifteen-year effort, this handbook covers the gamut of oil and gas engineering topics to provide a reliable source of engineering and reference information for analyzing and solving problems. It also reflects the growing role of natural gas in industrial development by integrating natural gas topics throughout both volumes. More than a dozen leading industry experts-academia and industry-contributed to this two-volume set to provide the best , most comprehensive source of petroleum engineering information available.

Book Description
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

Book Description
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).
