VOLUMETRIC GAS RESERVOIR ENGINEERING
Volumetric gas reservoir engineering is introduced at this early stage in the book because of the relative simplicity of the subject. lt will therefore be used to illustrate how a…
OIL RECOVERY: RECOVERY FACTOR
Equation (1.2), for the STOIIP, can be converted into an equation for calculating the ultimate oil recovery simply by multiplying by the recovery factor (RF), which is a number between…
FLUID PRESSURE REGIMES
The total pressure at any depth, resulting from the combined weight of the formation rock and fluids, whether water, oil or gas, is known as the overburden pressure. In the…
BASIC CONCEPTS IN RESERVOIR ENGINEERING
In the process of illustrating the primary functions of a reservoir engineer, namely, the estimation of hydrocarbons in place, the calculation of a recovery factor and the attachment of a…
Formation damage
Producing formation damage has been defined as the impairment of the unseen by the inevitable, causing an unknown reduction in the unquantifiable. In a different context, formation damage is defined…
Formation damage from paraffins and asphaltenes
Perhaps the most common formation damage problem reported in the mature oil-producing regions of the world is organic deposits forming both in and around the wellbore. These organic deposits fall…
Scale problems in production
Wells producing water are likely to develop deposits of inorganic scales. Scales can and do coat perforations, casing, production tubulars, valves, pumps, and downhole completion equipment, such as safety equipment…
Nodal analysis
Systems analysis has been used for many years to analyze the performance of systems composed of multiple interacting components. Gilbert was perhaps the first to introduce the approach to oil and…
Flow through chokes
A wellhead choke controls the surface pressure and production rate from a well. Chokes usually are selected so that fluctuations in the line pressure downstream of the choke have no…
Tubing Selection, Design, and Installation
IntroductionTubing is the normal flow conduit used to transport produced fluids to the surface or fluids to the formation. Its use in wells is normally considered a good operating practice.…
