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
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
Used to clean the borehole, stabilize rock, control pressures, or enhance drilling rates, drilling fluids and their circulation systems are used in all phases of a drilling operation. These systems are highly dynamic and complicated to model until now. Written by an author with over 25 years of experience, Applied Drilling Circulation Systems: Hydraulics, Calculations and Models provide users with the necessary analytical/numerical models to handle problems associated with the design and optimization of cost-effective drilling circulation systems. The only book which combines system modeling, design, and equipment, Applied Drilling Circulation Systems: Hydraulics, Calculations and Models provides a clear and rigorous exposition of traditional and non-traditional circulation systems and equipment followed by self contained chapters concerning system modelling applications. Theories are illustrated by case studies based on the author’s real life experience. The book is accompanied by a website which permits readers to construct, validate, and run models employing Newtonian fluids, Bingham Plastic fluids, Power Law fluids, and aerated fluids principles. This combination book and website arrangement will prove particularly useful to drilling and production engineers who need to plan operations including pipe-tripping, running-in casing, and cementing. In-depth coverage of both on- and offshore drilling hydraulics. Methods for optimizing both on- and offshore drilling hydraulics. Contains problems and solutions based on years of experience.
