A means of controlling the undesirable production of sand from weak sandstone formations. Sand consolidation chemically binds the grains of sand that make up the formation matrix while maintaining sufficient permeability to achieve viable production rates.
Industry:Oil & gas
A measure of the effectiveness of an enhanced oil recovery process that depends on the volume of the reservoir contacted by the injected fluid. The volumetric sweep efficiency is an overall result that depends on the injection pattern selected, off-pattern wells, fractures in the reservoir, position of gas-oil and oil/water contacts, reservoir thickness, permeability and areal and vertical heterogeneity, mobility ratio, density difference between the displacing and the displaced fluid, and flow rate.
Industry:Oil & gas
A measure of the amount of light reflected by a fluid from an optical probe. It is the same as the relative refractive index of light between the probe and the fluid, being close to 1 in gas, 1. 35 in water and 1. 5 in oil.
Industry:Oil & gas
A measure of heat energy required to raise the temperature of one pound of water by one degree Fahrenheit. British thermal unit is abbreviated as BTU.
Industry:Oil & gas
A measure of a curve describing the statistical frequency distribution in the region about its mode; the relative "peakedness" of the distribution. This measure is used in the description of wireline curves and in schemes that attempt to correlate them from well to well.
Industry:Oil & gas
A mathematical tool used in production engineering to assess well performance by plotting the well production rate against the flowing bottomhole pressure (BHP). The data required to create the IPR are obtained by measuring the production rates under various drawdown pressures. The reservoir fluid composition and behavior of the fluid phases under flowing conditions determine the shape of the curve.
Industry:Oil & gas
A means of assessing reservoir performance by measuring flow rates and pressures under a range of flowing conditions and applying the data to a mathematical model. Fundamental data relating to the interval under test, such as reservoir height and details of the reservoir fluids, are also input. The resulting outputs typically include an assessment of reservoir permeability, the flow capacity of the reservoir and any damage that may be restricting productivity.
Industry:Oil & gas
A mathematical tool used in production engineering to assess the performance of the completion string by plotting the surface production rate against the flowing bottomhole pressure. The fluid composition and behavior of the fluid phases in the specific completion design will determine the shape of the curve. The TPC is used with the inflow performance relationship to predict the performance of a specific well.
Industry:Oil & gas
A mathematical computation that accounts for the flow-rate history in analytical models generated to match with pressure-transient test data. The pressure-derivative response can be distorted in late-time data by the effects of superposition in time, except in data acquired from an initial drawdown. Analysts must be aware of this limitation in diagnosing reservoir features from the pressure-derivative response.
Industry:Oil & gas
A mathematical entity with components that change in a particular way in a transformation from one coordinate system to another. Tensor methods are used in "upscaling" reservoir parameters for use in reservoir simulation studies.
