Download or read book Modelling Emergency Situations in the Drilling of Deep Boreholes written by Sergii Glazunov and published by Cambridge Scholars Publishing. This book was released on 2019-10-31 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: The era of easily acquiring oil and gas is over. Now, to extract these resources, deep vertical and curvilinear, off-shore and ground-based boreholes are drilled in inclement climate conditions and in complex heterogeneous tectonic rocks. Additional novelties have also been assimilated into these technologies by the shale revolution. The techniques and methods of borehole drivage are developing so fast that scientific understanding and substantiation have no time to refine them. Therefore, as a rule, different unpredictable emergency effects and overall failures accompany these procedures. The gravest of these are buckling of the drill strings, their resonant vibrations, their sticking during dragging and twisting, the self-triggering of torsional relaxation vibration, and the self-excitation of forward, backward, and superfast bit whirlings. To analyse these phenomena, this volume elaborates new mathematic models and numerical methods. On the basis of these, a special software was created, which allowed new results concerning the peculiarities of the affected phenomena to be achieved. The book will be of interest to borehole designers and specialists in mechanics and applied mathematics.

Download or read book Modern Trends in Structural and Solid Mechanics 1 written by Noel Challamel and published by John Wiley & Sons. This book was released on 2021-06-08 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book - comprised of three separate volumes - presents the recent developments and research discoveries in structural and solid mechanics; it is dedicated to Professor Isaac Elishakoff. This first volume is devoted to the statics and stability of solid and structural members. Modern Trends in Structural and Solid Mechanics 1 has broad scope, covering topics such as: buckling of discrete systems (elastic chains, lattices with short and long range interactions, and discrete arches), buckling of continuous structural elements including beams, arches and plates, static investigation of composite plates, exact solutions of plate problems, elastic and inelastic buckling, dynamic buckling under impulsive loading, buckling and post-buckling investigations, buckling of conservative and non-conservative systems and buckling of micro and macro-systems. This book is intended for graduate students and researchers in the field of theoretical and applied mechanics.
Download or read book Modern Well Design written by Bernt S. Aadnoy and published by CRC Press. This book was released on 1996-01-01 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern Well Design provides a systematic approach to improve the planning and the design of petroleum wells, and it contains a number of new and original contributions. Borehole stability issues are presented in a simple and understandable manner. Methods to estimate in-situ stresses and fracturing gradients are given. Also simple correlation methods to evaluate borehole collapse are given. In particular time-dependent hole problems are analysed. One of the most important chapters deals with a new method to define to optimal mud weight used to drill a new well. Field cases demonstrate improvements in a number of wells using this method. Hydraulic optimisation is also treated. For long reach wells new flow criteria are derived, which ensure good hole cleaning. The complete casing design process is reviewed, and the direct application of geomechanics is shown. This includes casing design and pressure testing. A complete design example is given, structured for easy verification and modification. A separate chapter is included on high-pressure-high-temperature (HPHT) wells. In addition, in order to supply a complete well design, a number of related issues are treated like operational problems and mud ballooning. To a large extent, the book covers application of geology and geomechanics into the well design process. In addition to serving as a text book, it is a good reference book for practising geologists and petroleum engineers. Rock mechanics specialists will find it an important tool for finding information on borehole stability problem modelling and in-situ stress determination.

Download or read book Drilling Boreholes for Handpumps written by Peter Wurzel and published by Skat. This book was released on 2001 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: This booklet seeks to suggest ways in which funds can be better used for making safe water available to the poor by illustrating how drilling costs can be reduced without compromising water quality, water quantity, or the productive life of the borehole. These arguments are directed towards the rural water supply sector as a whole. Those directly addressed are primarily decision makers, government civil servants, planners and implementers of water projects who are not experts in drilling, as well as technical people, project leaders, technical aid personnel etc. This publication is neither a detailed drilling manual nor a methodology of drilling methods.
