The PVT module of GEMINI helps the user to calculate some of the
basic PVT properties of oil and gas, that are required as inputs
to DST analysis, volumetric and material balance calculations,
given a limited set input data.

The Material Balance Module will calculate and plot volume of
fluids withdrawn from the reservoir (F/E) against the volume of
water influx (We/E) at regular time steps. Havlena-Odeh's method
of aquifer-fitting will be used to describe (approximate) and
aquifer that coupled with the reservoir selected, the F/E versus
We/E plot will be a straight line with unit slope. The intercept
of this straight line will provide the estimate of the
material-balance OOIP (volume of original oil in place).

The Gridding and Mapping Web Application is an interactive process
that assists the user in building simple color contour maps of
Oil & Gas Well data, the user is in control of what data
is to be mapped. This Web Application also saves the user's data
as Extensible Markup Language, XML, Files. It provides an ideal
solution for handling the rapidly expanding quantity and
complexity of information that needs to be delivered on the
Web.

The LAS File Viewer Web Site was created so that users may view
digital LAS Files (Log ASCII Standard version 2) on their PCs or
with a URL Address as long as the URL can be seen from your
browser. This web application also will plot a Rhomaa-Umaa
Lithology track if the LAS File has a Photoelectric, Bulk Density
and Neutron Porosity Curves in the file otherwise only the LAS
file curves will be plotted.

Correlation of petroleum reservoirs is a fundamental task in reservoir characterization used to establish the geometry of the reservoir and strata surrounding it and to delimit the distribution of flow units that comprise the reservoir. Correlations are primarily accomplished via construction of cross sections through the reservoir using wireline logs where depth patterns, trends, and surfaces define probable continuity within the reservoir between well locations. The correlations are validated through analyses of fluids recovered, flow tests, and possibly seismic surveys, in the later case if the reservoir is sufficiently thick to be seismically resolvable.
Note: This Web Application was designed to work with Kansas Geological Survey
(KGS) Files and Oil & Gas Well Data. Only KGS oil & gas wells in Kansas
with digital LAS files with litho density curves, i.e. gamma ray, photoelectric
factor, neutron porosity, and bulk density log curves, are considered.

The detection of cyclicity in sedimentary strata can be important to the understanding of the factors controlling sediment depositions. The presence of cyclic patterns and changes in their character have important consequences for geological interpretation, changes in wavelength may indicate changes in depositional facies.

The Rock Catalog Web Application was designed to help the
user locate Kansas Geological Survey's (KGS) Core Data and Core
Image Files. This web application is designed to allow the user
to create search constraints in such a way to filter the data by
their interest in data type. The user can construct measured
core data cross plots, i.e. Measured Porosity versus
Permeability data plots and display core images based on your
search constraints. This tools also allows the user to save the
images and plots to their pc by constructing a rock catalog web
page.

This original version of the Rock Catalog is being replaced by the new version, but you can find Version 1 here, Rock Catalog - Version 1
The Synthetic Seismogram algorithm that drives this module will convolve reflection coefficients with a first order Ricker Wavelet whose frequency is chosen by the User. This method is widely used in commercial synthetic seismogram software packages.

with digital LAS files with Sonic logs are considered.
