| Virtual Relative Permeability Curves |
This EXCEL spreadsheet with VBA macros creates Relative Permeability curves.
|
| Fluid Pressure Gradient Conversion |
This EXCEL spreadsheet converts fluid pressure gradients between psi/ft, psi/m and density.
|
| Guidelines for Interpreting Formation Pressure Data |
This PowerPoint presentaion file shows a step-by-step interpretation of MDT formation pressure (pretest) data.
|
| Process Formation Water Salinity Data |
This Zipped file contains an EXCEL spreadsheet and associated Visual Basic macros for
processing brine salinity data to obtain NaCl equivalent salinity and water resistivity.
|
| Brine Properties |
This EXCEL spreadsheet determines brine density, fluid pressure gradient, viscosity and sonic velocity using inputs of temperature, pressure and salinity. |
| Zoned Petrophysics Summary Tables |
This Zipped file contains an EXCEL spreadsheet and associated Visual Basic macros for
creating zoned Petrophysics summary tables.
|
| Zoned Petrophysics Crossplots |
This Zipped file contains an EXCEL spreadsheet and associated Visual Basic macros for creating zoned Petrophysics crossplots (scatter plots). |
| Reservoir Fluid Contacts |
This EXCEL spreadsheet and associated Visual Basic macros incorporates a statistical approach to calculate fluid contacts from formation pressure data. The method used in this spreadsheet
is particularily useful for noisy data and where there is little difference
between the oil and water density values. Included with this download is a Word document that describes three methods of calculating fluid contacts. |
| WireLineQC |
This zipped file contains example logging quality control forms. You are welcome to use or modify these forms. |
| ReservesCalculations |
This is a self-extracting zipped file containing an EXCEL spreadsheet
for calculating in-place and recoverable hydrocarbon volumes. Gross rock
volume is calculated using both the trapezoidal and pyramidal methods.
You are welcome to use or modify this file. |
| Hydrocarbon Volume |
This program distributed by Terra Firma Technology is an Excel 97 spreadsheet running VBA 5.0. It will
run on any machine using Windows 95 or NT running Microsoft Excel 97 from
the Office 97 suite. It determines in-place and reserves for prospects
and fields containing up to ten user defined reservoirs, waste zones and
sealing layers. Data are not entered directly into the spreadsheet but
via user forms, which ensures their validation. Custom help files provide
context sensitive help for the user. Both Imperial and metric units are
handled. The program is distributed as a self extracting archive. After
downloading, read the readme.txt file for more information. |
