Geophysics for Petroleum Engineers by Fred Aminzadeh,Shivaji N. Dasgupta Pdf
Geophysical techniques apply the principles of physics for study of physical responses of rocks under passive or active perturbation. Geophysical data acquisition, processing and interpretation are driven by established scientific principles. Data from geophysical tools provide coverage with spatially continuous high density measurements. Well data like cores and well logs provide vertically high resolution measurements at the well location, however, the distribution of wells is sparse and discontinuous. The detailed spatial coverage from geophysical data are calibrated with analysis of well logs, pressure tests, cores, geologic depositional knowledge and other information from appraisal wells. The methods use high precision sensors that measure the properties on the earth's surface, in oceans, in wells and from the air, also from satellites. They measure changes of physical properties and calibrate the measured geophysical attributes with rock properties. The data play important role in developing a gross reservoir model. The reservoir architecture or structure and the reservoir rock and fluid properties are derived from the analysis and data integration. Other reservoir properties that can affect geophysical measurements are density, oil viscosity, stresses, and fractures. The interpretation has inherent ambiguity or multiple interpretations. Geophysics contributes to reservoir characterization, reservoir monitoring and its management by adding maximum value in improving production plan and by minimizing risk e.g., risk of dry hole, risk of blow out, risk of in-efficient recovery process, among others. Multiple geologic parameters are assessed with the same geophysical data.
Seismic Data Interpretation and Evaluation for Hydrocarbon Exploration and Production by Niranjan C. Nanda Pdf
This book is meant for geoscientists and engineers who are beginners, and introduces them to the field of seismic data interpretation and evaluation. The exquisite seismic illustrations and real case examples interspersed in the text help the readers appreciate the interpretation of seismic data in a simple way, and at the same time, emphasize the multidisciplinary, integrated practical approach to data evaluation. A concerted effort has been made for the readers to realize that mindless interpretation of seismic data using sophisticated software packages, without having a grasp on the elementary principles of geology and geophysics, and coupled with their over-reliance on workstations to provide solutions can have appalling results all too very often.

Introduction to Petroleum Exploration and Engineering by Andrew Palmer Pdf
This book is an introduction to oil and gas designed to be both accessible to absolute beginners who know nothing about the subject, and at the same time interesting to people who work in one area (such as drilling or seismic exploration) and would like to know about other areas (such as production offshore, or how oil and gas were formed, or what can go wrong). It begins by discussing oil and gas in the broader context of human society, and goes on to examine what they consist of, how and where they were formed, how we find them, how we drill for them and how we measure them. It describes production onshore and offshore, and examines in detail some instructive mishaps, including some that are well known, such as Deepwater Horizon and Piper Alpha, and other lesser known incidents. It looks at recent developments, such as shale oil, and concludes with some speculation about the future. It includes many references for readers who would like to read further. Mathematical content is minimal.

TECHNOLOGICAL ADVANCEMENT IN THE OIL AND GAS INDUSTRY: A CONSIDERATION OF THE NODAL SEISMIC SYSTEM by Adeolu Aderoju Pdf
Technology has proved its credibility by helping us to combat some of the most important challenges in decades. On a high interest, our yesterday’s concerns are now our jubilations today. Also, various innovations that technology is offering our industry today have shown us clearly that the industry cannot afford to shuttle its today’s cares until tomorrow. It is even more interesting that today creative minds in the industry are already gazing into the future, seeing about tackling our tomorrow’s challenges right now. All these findings validate the simple fact that: ‘the oil and Gas industry is a technology based and innovation driven’ (David, 2011). The phase change and its adaptation are so rapid that if professionals fail to yield to it or feel reluctant to its tingle, they may find it hard to catch up with the transiting train. The thrust of the drive witnessed by the industry in the recent decade is intense. This is wholly responsible to the world’s high demand for our commodity (Oil and Gas), our daily venture into the ultra-deepwater exploration, unconventional resource exploration systems which always beckon on new and strong techniques. All of these are enough to charge professionals to be aware of the demands of their fields by yielding their thoughts to the present breakthrough and preparing to face the next decade’s challenges. One important breakthrough that technology has offered the seismic data acquisition field of recent is the ‘Nodal Seismic System’. The success is currently attracting a great deal of key players from every end of the industry and has kept discussions on over time. The advancement is also known as Cableless, Wireless or Nodal seismic acquisition system, as it may be. It is an improvement over the conventional cabled seismic acquisition system. An overview of this advancement in relation to the challenges it solves has been looked into in his article.
Geophysics for Petroleum Engineers by Fred Aminzadeh,Shivaji N. Dasgupta Pdf
Geophysical methods are being applied that are specifically relevant to the exploration of and production from unconventional reservoirs. While many of the techniques have common applications for both conventional and unconventional reservoirs, there are also some significant differences in focus. Much of the unconventional reservoirs are from shale formations. Characterizing of fracture system in such reservoirs is of prime importance not only to identify the “sweet spots” for well placement but also for optimum drilling and production from such fractured reservoirs. Combining conventional and microearthquake seismic data has proven to improve the characterization process. Another factor for drilling through shale reservoirs is the need for stimulation through hydraulic fracturing. Use of microseismic data for monitoring the frac process has gained prominence in recent years. Different types of design to acquire such geophysical data and to utilize them for multistage fracking process as well as their integration with the conventional seismic data have been developed.
Seismic Attributes as the Framework for Data Integration Throughout the Oilfield Life Cycle by K. J. Marfurt Pdf
Useful attributes capture and quantify key components of the seismic amplitude and texture for subsequent integration with well log, microseismic, and production data through either interactive visualization or machine learning. Although both approaches can accelerate and facilitate the interpretation process, they can by no means replace the interpreter. Interpreter "grayware" includes the incorporation and validation of depositional, diagenetic, and tectonic deformation models, the integration of rock physics systematics, and the recognition of unanticipated opportunities and hazards. This book is written to accompany and complement the 2018 SEG Distinguished Instructor Short Course that provides a rapid overview of how 3D seismic attributes provide a framework for data integration over the life of the oil and gas field. Key concepts are illustrated by example, showing modern workflows based on interactive interpretation and display as well as those aided by machine learning.
