This book was released on 2008 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Well drilling is an important process for extracting oil, natural gas, water, and mineral materials. Opening wells requires boring through earth formations, which can range from very soft to very hard. Penetrating into such formations requires specialized tools and operation procedures which should be employed based on the environment and application. Rotary drilling, in which a drill bit is used to crush the rock and penetrate into the formation, is one of the main methods of well drilling. Rotary cone bits are one of the main types of drill bits used for rotary drilling. There are two main problems encountered when drilling with rotary cone bits. Excessive vibration can cause damage to the entire system and can decrease efficiency of the drilling process. Failure of the bit's bearings and seals can also result in damage to the bit and cessation of the drilling process. In recent years, a great deal of research has been undertaken to address these problems and find appropriate solutions to improve drilling efficiency and production rate while reducing the overall cost of drilling. In this thesis, a new design for rotary cone bits, with the objective of improving overall drilling performance, is presented. First, a new pattern for distribution of inserts over the cone is presented, which results in reduced vibration of the drillstring. Second a new design for the bit's bearings is introduced that is capable of operating in harsh environments. Finally, an experimental set-up is introduced to evaluate the performance of the proposed designs.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In oil and gas industry, drilling provides the path to exploit underground resources. Increasing rate of penetration (ROP) is one of the goal of drilling engineers to build this path. This dissertation focuses on study of a novel drilling technique, i.e. passive Vibration Assisted Rotary Drilling (pVARD) technique, and characterization of drilling mechanisms in comparison to the other two widely used drilling techniques, i.e. rotary drilling and rotary-percussion drilling (RPD). In terms of the fundamental differences between drill bit vibrations from three drilling techniques, seismic while drilling (SWD) and acoustic emission (AE) technologies are used to study drill bit sources and corresponding drilling mechanisms. First, geomechanics response of synthetic rock is studied using AE technique based on standard confined compressive strength (CCS) tests. This research aims to compare synthetic to natural rock in terms of deformation properties and provides support for the following drill-off test (DOT). Second, pVARD tool drillings are conducted in comparison to rotary drilling both in laboratory and field tests using AE and SWD techniques, respectively. In laboratory, AE signal energy and cutting size distribution are correlated to polycrystalline diamond compact (PDC) bit drilling performance. Results show that micro crack is generated from drag bit shearing action and the higher AE energy, coarser cuttings and higher ROP are obtained. In field test, surface wave energy and frequency bandwidth are correlated to drill bit vibration and drilling performance. Third, laboratory active vibration DOTs are conducted to study the penetration mechanisms from a diamond coring bit using AE technique. Spectral and energy analysis of the AE signals indicate that the higher ROP and larger cutting size are correlated with a higher AE energy and a lower AE frequency, indicating larger fractures are being created to generate the larger size of cuttings. Fourth, rotary-percussion drilling sources are studied by two field experiments on weak shales and hard arkose using SWD technique. Characterization of these sources consist of spectral analysis and mean power study, along with field measurements of the source radiation patterns. In addition, polarization analysis is conducted on P-waves recorded at surface geophones for understanding the particle motions.

Book excerpt: Seismic While Drilling: Fundamentals of Drill-Bit Seismic for Exploration, 2nd edition, revised and extended gives a theoretical and practical introduction to seismic while drilling by using drill-bit noise. While drilling seismic methods using surface sources and downhole receivers are also analysed. The goal is to support the exploration geology with geophysical control of drilling, and to build a bridge between geophysicists involved in seismic while drilling, drillers and exploration geologists. This revised and extended edition includes new topics such as novel drilling technology, downhole communication, ground-force drill-bit measurement, SWD seismic interferometry, and fiber optic (DAS). A new section is dedicated to well placement and geosteering. Like the first edition, Seismic While Drilling, 2nd edition also includes examples of SWD analysis and application on real data. - Addresses fundamental knowledge on geophysical principles related to acoustics and seismic waves as well as basic borehole waves and drilling - Includes new technological and methodological developments since the publication of the first edition - Provides new examples for applications in geothermal and analysis of diffractions, offshore marine, and tunnel seismic while drilling (TSWD)

Available in PDF, EPUB and Kindle. Book excerpt: Developments in Geographic Information Technology have raised the expectations of users. A static map is no longer enough; there is now demand for a dynamic representation. Time is of great importance when operating on real world geographical phenomena, especially when these are dynamic. Researchers in the field of Temporal Geographical Information Systems (TGIS) have been developing methods of incorporating time into geographical information systems. Spatio-temporal analysis embodies spatial modelling, spatio-temporal modelling and spatial reasoning and data mining. Advances in Spatio-Temporal Analysis contributes to the field of spatio-temporal analysis, presenting innovative ideas and examples that reflect current progress and achievements.
