- Company Profile:
An arrangement of piping or valves designed to control, distribute and often monitor fluid flow. Manifolds are often configured for specific functions, such as a choke manifold used in well-control operations and a squeeze manifold used in squeeze-cementing work. In each case, the functional requirements of the operation have been addressed in the configuration of the manifold and the degree of control and instrumentation required.
Industry:Oil & gas
An area in which hydrocarbon accumulations or prospects of a given type occur. <br>For example the shale gas plays in North America include the Barnett, Eagle Ford, Fayetteville, Haynesville, Marcellus, and Woodford, among many others. Outside North America, shale gas potential is being pursued in many parts of Europe, Africa, Asia, and South America. <br>
Industry:Oil & gas
An approach to stochastic imaging or simulation of a reservoir that is nonparametric. The Gaussian approach is a simpler approach that includes a normal score transform of the data to produce a new variable that is univariate and normally distributed.
Industry:Oil & gas
An area allotted to a well by regulations or field rules issued by a governmental authority having jurisdiction for the drilling and production of a well.
Industry:Oil & gas
An approach to performing risk analysis on any project with uncertain input data. Generally, numbers are selected from representative input data and then used in iterative, CPU-intensive calculations to find the most likely outcome and the range of probable outcomes. The uncertainty in the output also provides a measure of the validity of the model. The technique is applied to financial investment portfolio and investment risk analysis as well as scientific applications. <br>Monte Carlo analysis methods are used in the oil field to estimate the risks involved in new exploration projects, evaluation of development schemes and evaluation of validity of reservoir models.
Industry:Oil & gas
An apparatus for measuring the permeability of a core sample. Measurements are made either by placing the sample in a chamber (also known as a core holder), or by placing a probe on the surface of the sample. Core-holder measurements are made either with gas or liquid, and either in steady state or unsteady-state conditions. Other variables include the confining pressure and the direction of measurement, which can be axial (along the axis of a cylindrical core sample), transverse (perpendicular to the axis), or radial (to the center of a hollow cylinder). In probe measurements, gas is injected into the sample under either steady- or unsteady-state conditions. Probe permeameters are also known as minipermeameters.
Industry:Oil & gas
An apparatus for cleaning core samples using the distillation extraction method. In the Soxhlet apparatus (also called extractor, or chamber), the sample soaks in hot solvent that is periodically siphoned off, distilled and returned to the sample. The process continues until the siphoned-off solvent becomes clear. In the Soxhlet apparatus, the sample soaks in the solvent, while in the Dean-Stark apparatus, the solvent flows through the sample from top to bottom.
Industry:Oil & gas
An annotation made on a log print once every minute. By reading the depth interval between each minute mark, it is possible to check the logging speed. Minute marks are typically made by blanking out the vertical grid line on the far left of the print for a short interval every minute.
Industry:Oil & gas
An analytical tool used in forecasting the performance of the various elements comprising the completion and production system. NODAL* analysis is used to optimize the completion design to suit the reservoir deliverability, identify restrictions or limits present in the production system and identify any means of improving production efficiency. <br><br>*NODAL (production system analysis) is a mark of Schlumberger.
Industry:Oil & gas
An angle that characterizes the ability of an azimuthal logging measurement to resolve changes in different directions around the tool; alternatively, the smallest angle for which a significant change can be detected.
