The book comprises two parts: Pressure and Flow Well Testing (Part I) and Temperature Well Testing (Part II), and contains numerous authors' developments. Due to the similarity in Darcy's and Fourier's laws the same differential diffusivity equation describes the transient flow of incompressible fluid in porous medium and heat conduction in solids.

Well Testing is recognised by many operating oil and gas companies to be the most hazardous operation they routinely undertake. Therefore, it is of great importance that such operations are extremely well planned and executed.This handbook covers all the major "Operational Aspects of Oil and Gas Well Testing" and uses a structured approach to guide the reader through the steps required to safely and effectively plan a well test operation under just about any circumstances world wide.Safety procedures and well testing recommended practices are rigorously addressed in this book, as are the responsibilities of those persons involved in well testing operations.Perforating equipment, drill stem test equipment and bottom hole pressure gauges are discussed in detail in the book. There is also a very valuable section on sub sea equipment, an area often not well understood even by experienced engineers who may have been primarily involved with land or jackup rigs.A major part of the book is the detailed coverage of the equipment and instrumentation that makes up a surface well testing package. It also covers operational and testing related problems such as, hydrates, wax and sand, and offers the reader some possible solutions.There are useful chapters on sampling, onsite chemistry, coil tubing and nitrogen operations and basic stimulation as they relate to well testing. Finally there is an extensive section of appendices covering useful engineering calculations and there is a complete example of a detailed well testing programme.

Well test planning is one of the most important phrases in the life cycle of a well, if done improperly it could cost millions. Now there is a reference to ensure you get it right the first time. Written by a Consultant Completions & Well Test Engineer with decades of experience, Well Test Planning and Operations provides a road map to guide the reader through the maze of governmental regulations, industry codes, local standards and practices. This book describes how to plan a fit-for-purpose and fault free well test, and to produce the documents required for regulatory compliance. Given the level of activity in the oil and gas industry and the shortage of experienced personnel, this book will appeal to many specialists sitting in drilling, completion or exploration departments around the world who find themselves in the business of planning a well test, and yet who may lack expertise in that specialty. Nardone provides a roadmap to guide the planner through this complex subject, showing how to write the necessary documentation and to coordinate the many different tasks and activities, which constitute well test planning. Taking the reader from the basis for design through the well Test program to well test reports and finally to the all-important learning to ensure continuous improvement. - Identification and prioritization of well test objectives - Confirmation of well test requirements - Preparation of detailed well test programs - Selection and qualification of test equipment - Onsite (onshore and offshore) engineering support and test supervision - Detailed well test interpretation - Definition of Extended Well Test (EWT) requirements

Geothermal Well Test Analysis: Fundamentals, Applications and Advanced Techniques provides a comprehensive review of the geothermal pressure transient analysis methodology and its similarities and differences with petroleum and groundwater well test analysis. Also discussed are the different tests undertaken in geothermal wells during completion testing, output/production testing, and the interpretation of data. In addition, the book focuses on pressure transient analysis by numerical simulation and inverse methods, also covering the familiar pressure derivative plot. Finally, non-standard geothermal pressure transient behaviors are analyzed and interpreted by numerical techniques for cases beyond the limit of existing analytical techniques. Provides a guide on the analysis of well test data in geothermal wells, including pressure transient analysis, completion testing and output testing Presents practical information on how to avoid common issues with data collection in geothermal wells Uses SI units, converting existing equations and models found in literature to this unit system instead of oilfield units

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.

This book is about the technology of using fluid production or injection and pressure measurement signals from wellbores and relating those signals to the subsurface geology and subterranean reservoir properties. It is aimed at students of well-testing and practicing petroleum engineers or geoscience professionals for subsurface characterization and modeling. The topics include the art and science of well-test analysis, pattern recognition of rate and pressure signals, and a quantitative approach for estimating important subsurface geological parameters for subsurface aquifers and reservoirs containing oil, gas, and geothermal resources. The book is also particularly of value as a guide to asset managers actively developing unconventional reservoirs and CCUS.
