Principles of applied reservoir simulation

The present invention relates to methods for controlling the migration of particulates, such as proppant and formation sands, from subterranean formations using solutions of tackifying materials. One embodiment of the present invention provides a method of treating a subterranean formation comprising the steps of placing a tackifying composition into the subterranean formation and then placing an after-flush fluid into the subterranean formation.

Injection compositions for a variety of microemulsion and surfactant floods can be represented on equilibrium ternary diagrams with coordinates surfactant-cosolvent, brine, and oil. That portion of such a diagram having economic significance, divides into a single-phase region and a multiphase region. Within the single-phase region, micellar structure is studied in relation to effects of salinity and cosolvent on viscosity, optical birefringence and electrical resistivity. Within the multiphase region, effects on phase behavior, interfacial tension and solubilization parameter are determined as functions of salinity, brine composition, temperature, surfactant structure, cosolvent, and oil aromaticity. Correlations are found between interfacial tension and solubilization parameter that are useful in preliminary screening of surfactants for oil recovery potential. When, by any means, extent of the multi-phase region is reduced, a circumstance favorable to displacement in the miscible mode; a concomitant effect is that interfacial tensions are also reduced, favoring displacement in the immiscible mode.

Some physicochemical aspects of microemulsion flooding: a review

The present invention provides reduced-density coated particulates and methods for enhancing the transport of such particulates into well bores and fractures, and for enhancing the conductivity and permeability of subterranean formations using such particulates, and for sand control treatments using such particulates. The reduced-density, coated particulates of the present invention generally comprise particulate having a surface and a coating wherein the surface comprises a porous or partially hollow geometry and coating is capable of trapping a fluid between the particulate's surface and the coating.

This book is intended to be a reservoir engineering book for college students, but its not the usual college text book. It is a modern and very practical guide offering reservoir engineering fundamentals, advanced reservoir related topics, reservoir simulation fundamentals, and problems and case studies from around the world. It is designed to aid students and professionals alike in their active and important roles throughout the reservoir life cycle (discovery, delineation, development, production, and abandonment), and in the various phases of the reservoir management process (setting strategy, developing plan, implementing, monitoring, evaluating, and completing). Benefits & Features:The authors bring to this book their life-long experience and expertise in reservoir engineering and simulation techniques and practice. The goal is to present a comprehensive book, starting from basic principles and leading to real-life reservoir management aided by simulation. This practical book explores the functions of reservoir engineers, and how they analyze, think and work in real life situations. It presents: Rock and fluid properties, fluid flow principles, well test analysis, and reservoir performance analysis techniques. New topics such as reserves, reservoir economics, risk and uncertainties, probabilistic methods, and recovery processes. Role of reservoir simulation models in enhancing basic reservoir engineering concepts and practice. Computer-based tools, including reservoir simulation, are used extensively in this book to illustrate various concepts related to reservoir engineering. Finally, the book offers class projects where the students can apply what they have learned to treat their problems. This book will serve the students and the industry well.

Practical Enhanced Reservoir Engineering: Assisted With Simulation Software

The amount of a petroleum recovery chemical retained within a subterranean reservoir is predicted by first gathering data from at least one injection-soak-production cycle in a single well wherein the produced fluids are monitored for both the chemical concentration in the produced fluid as well as the concentration of a nonabsorbing tracer and, second, utilizing this data in a chemical flood mathematical model to simulate at least one repetition of the injection-soak-production cycle. The simulated cycles are repeated until the simulated produced fluid concentration of the chemical is virtually the same as the actual produced fluid concentration of the nonabsorbed tracer. The amount of the chemical retained per unit of reservoir volume is then determined by conventional techniques.

Integrated Petroleum Reservoir Management: A Team Approach

The modern reservoir management process involves goal setting, planning, implementing, monitoring, evaluating, and revising plans. Setting a reservoir management strategy requires knowledge of the reservoir, technology, and an understanding of the business, political, and environmental climates. Formulating a comprehensive management plan involves depletion and development strategies, data acquisition and analyses, geological and numerical model studies, production and reserves forecasts, knowledge of facilities requirements, economic optimization, and management approval. Implementing the plan requires management support; field personnel commitment; and multidisciplinary, integrated teamwork. Project success depends on careful monitoring/surveillance and thorough ongoing evaluation of its performance. If the actual performance of the project does not agree with the expected performance, the original plan should be revised and the cycle (implementing, monitoring, and evaluating) reactivated. This paper presents sound reservoir management concepts and methods including a team approach based on integration of geoscience and engineering professionals, tools, technology, and data.
