They are used primarily in equations to show how the theoretical concepts are related to the working program.

Tool will be used more conceptually in discussing interpretation models. In sand-shale reservoirs PHIT is not recommended, because it adds little to the solution. Look at Table 10 again and consider what would happen if the sand were arkosic and you wanted to include orthoclase in the model. Such an approximation is valid only over a specific range of porosities and fluid saturations. Whenever you do apply a constraint, document it. Polygons into Petrel Zoom: However, note that since bound water XBWA is solved for as a dependent variable, nfc does not include it.

Two against one in an optimized solution will have an answer weighted towards the two tools that agree no gas. Since response parameters are used in the evaluation of some constraints, the zonation of response parameters affects the zonation of constraints. Therefore, the terms volumes and formation components, or just components, are often used interchangeably. That is, they take on a single value throughout the processing interval.

Additionally, there are broken bonds around the edges at the end of the horizontal sheets of silica tetrahedrons and aluminum octahedrons of the clay particle, contributing to the charge imbalance. The usual value assumed for mc2 is 0. Temperature corrections are made under the following conditions: The equations describe the logging data and supplementary response equations that are available. The cementation factor varies much more strongly with the Qv of the formation when using the Waxman-Smits model than with the Dual Water model.

Another difference is that the parameters in Table 6 have a small pressure dependence. Because isolated and parallel porosity ISOL and PARA are viewed as being the same in the flushed and undisturbed zones, the invasion factor has no influence over them.

There are no default geofrwme for rocks and for many fluids. Mnemonics that have a subscript of DC also denote dry egoframe values.

The hydrogen index of a hydrocarbon can be computed as a function of the hydrogen density, as discussed in Schlumberger Interpretation Principles.

Salinity Editor Because the program needs to know salinities before it can perform some other operations, such as giving the Zoned Parameter Editor proper values, the ELANPlus program has a special editor, the Salinity Editor, for entering salinity-related parameter values, including those needed to compute a temperature, if necessary.

Shear data must be entered into equations used for compressional data, with appropriate parameter changes. The Log Analyst 26 1 That is a mathematical fact of life, but it represents only the minimum requirement.

It assumes that the hydrocarbon density in the flushed and undisturbed zones is the same. It is often possible to provide usable default values for?

The reduction in hydrogen index for water when salinity increases are taken into account by using the matrix term. It is selected to be consistent with TNPH data and salinity correction. There are two exceptions to the rule: The same results would also be obtained with the uncertainty of A and D set to 10 and the manuall of B and C set to 0.

Any interpretation system—and the ELANPlus system is no exception— must know the volume and type of hydrocarbon in the flushed zone in order to make the proper hydrocarbon corrections especially gas corrections to the porosity measurements.

That is done for the density tool RHOB in the following equation. Because rocks are de? If there are exactly as many independent equations as there are unknowns, the system is said to be determined, or deterministic. Deep conductivity describes the total amount of hydrocarbons. Theoretically, solution uncertainties are made up of two parts: Rocks are considered to be user-de?

Following is a subset of the response parameters required for the nonlinear neutron equation: Figure 8 is a plot of DT versus porosity for dolomite, calcite, and quartz.

The SP used by these programs must have its baseline set to 0. How do I decimate an interpolated surface back to its original picked lines? Occasionally, the subscript WC will be used to emphasize that a particular parameter or volume is a wet clay value. Vertical Continuity The solution of one data level is completely independent from the solution at adjacent data levels.

This is a quick reference guide of the formats best suited to transfer data into Petrel. For more information see Chapter 6, Constraints. Those calibrated in one area or zone may not apply elsewhere.

An exception might be made either if the uncertainty of the tool is being driven by a curve at least partly determined by hole rugosity, or if manuaal very carefully zone the uncertainty parameter. The Linear Conductivity equation is an approximation of the Dual Water equation. Unfortunately, all of the answers will be skewed, including porosity and hydrocarbon beoframe. Rocks do not have default parameter values other than Absent.

For very fresh waters the Rwa term in the denominator becomes very geofrae, which causes the equivalent conductivity to approach 0. Assume a formation temperature of ? Fluids are less well de?
