|Book Details :|
The purpose of the monograph is to present in a clear and concise form methods of utilizing the data of temperature surveys in deep boreholes as well as the results of field, laboratory, and analytical investigations in geothermics to the wide range of petroleum reservoir engineers, drilling and production engineers, petroleum geologists, and geophysicists.
Although some aspects of this book have been discussed in several monographs (Kappelmeyer and Haenel, 1974; Proselkov, 1975; Cheremenskiy, 1977; Gretener, 1981; Prats, 1982; Jorden and Campbell, 1984; Handbook of Terrestrial Heat-Flow Density Determination, Eds.: Haenel, Rybach, and Stegena, 1988 ) and numerous papers, at present no monographs on this topic are available to the petroleum engineers.
This monograph is developed mainly from notes used for six years in courses (Applied Geothermics, Impact of Elevated Ternperatures and High Pressures on Drilling and Production, Arctic Drilling and Production) given to senior and graduate students at the Petroleum Engineering and Geosciences Department of the Louisiana Tech University.
All chapters of the monograph (Introduction, Temperature Field of Reservoirs, Wellbore and Formations Temperatures During Drilling, Wellbore and Formations Temperatures During Shut-in, Cementing and Casing, Production and Injection Wells, Interpretation and Utilization of Temperature Data, Appendix-Thermal Properties of Formations, Computer Programs) are introduced at a level that will make them accessible to field operators and staff.
Mathematical formulas are presented in a concise form and illustrated by tables and numerical examples. Many field examples are provided to develop an understanding of the interpretation and utilization of temperature data.
The objective of this monograph is a valid presentation of the state of knowledge and prediction of downhole and formations temperatures during well drilling, well completion, shut-in, and production. Our intent is to reach drilling engineers (impact of elevated temperatures on well drilling and completion technology, Arctic drilling);
Production engineers (temperature regime of production, injection, and geothermal wells, Arctic production); reservoir engineers (temperature field of reservoirs, thermal properties of formations and formation fluids);
Well logging engineers (interpretation of electrical resistance, mud density, and temperature logs); geophysicists and geologists (interpretation of geophysical data, calculation of the terrestrial heat flow, reconstruction of the past climate).
The Author also hopes that the monograph will be used as a textbook for senior and graduate petroleum engineering students. The Society of Petroleum Engineers has suggested a set of standard symbols for use in petroleum engineering and an effort has been made to adhere to those standards. In the monograph International System (SI) of units is used with practical oilfield units in brackets.
When reference data (figures and tables) are used the original units will be maintained. The coefficients in empirical equations are presented in such way that the Reader can use them either with the practical oilfield units (prevalent in many many, including the U.S.), or with the SI set of units. Conversion factors are presented in the Appendix A.
