From its modest beginnings as a rudimentary productivity test, well testing has progressed to become one of the most powerful tools for determining complex reservoir characteristics. This fifth book in the Schlumberger Testing Services set summarizes the state of the art in well test interpretation.

Petroleum systems 

Geologic principles and geologic time
Rock and minerals, rock cycle, reservoir properties
Hydrocarbon origin, migration and accumulation

Reservoir stimulation and artificial lift are the two main activities of the production engineer in the petroleum and related industries. The main purpose of stimulation is to enhance the property value by the faster delivery of the petroleum fluid and/or to increase ultimate economic recovery. Matrix stimulation and hydraulic fracturing are intended to remedy, or even improve, the natural connection of the wellbore with the reservoir, which could delay the need for artificial lift. This chapter outlines stimulation techniques as tools to help manage and optimize reservoir development.  Understanding stimulation requires understanding the fundamental issues of petroleum production and the position and applicability of the process. <...>

The purpose of this course is to introduce you to Petrel Geophysics functionality and the workflows. You will go thorough different functionalities in Petrel and learn how to efficiently use these for interpreting 2D/3D seismic data. The powerful tools and algorithms can be used to calculate size/area of your leads and prospects which, in turn, can be used for reserves estimation.
You will be provided with a ready-to-use Petrel 2013 project containing 2D/3D seismic and well data.
The exercises provide hands on training that enables you to explore the functionalities through dedicated exercises. <...>

For any oilfield analysis, it is necessary to understand how to calculate areas, volumes and capacities. Fortunately, areas and capacities of tubing and casing are in most field handbooks and in the engineering tables of this book. Most readers of this document will remember how to calculate areas and volumes from grade school, so only a brief review is presented here. The engineering tables at the back of this book provide all the necessary data to determine well capacities quite easily. The first few sample problems are solved manually to show how the tables were generated. Thereafter, the tables will be used as much as possible to simplify the problem solving. Understanding how the data was generated will make the calculations more meaningful and the tables easier to use. In any case, a clear understanding of the basic principles is necessary before proceeding as subsequent concepts will build on prior ones <...>

Electrical well logging was introduced to the oil industry over a half century ago. The first log was recorded on September 5, 1927, in a well in the small oil field of Pechelbronn, in Alsace, a province of northeastern France. This log, a single graph of the electrical resistivity of the rock formations cut by the borehole, was recorded by the “station” method. The downhole tool (called a sonde) was stopped at periodic intervals in the borehole, measurementsw ere made, and the calculated resistivity was hand-plotted on a graph. This procedure was repeated from station to station until the entire log was recorded.<...>

Цель этого курса - построить 3D модель, содержащую разломы, горизонты и свойства. По этой модели будут проведены подсчет запасов, проектирование свойств и подготовка карт для печати. Вы научитесь загружать данные, строить разломы по исходным данным разных типов, строить грид по модели разломов и вставлять в него горизонты (во временном домене). Затем мы преобразуем в глубину созданные горизонты (и весь грид) и разобьем модель на зоны и слои. После этого на основании информации со сквпжин мы рассчитаем петрофизические свойства модели.

На примере тестового проекта, подготовленного на основе геолого-геофизической информации типичного российского месторождения, рассмотрены вопросы технологии построения трехмерных компьютерных геологических моделей продуктивных пластов в программном комплексе Petrel 2011 (Schlumberger).
