BKZRt (Lateral Log Interpretation & Borehole Corrections)
Software Description: 
The program consists of two modules: Lat-Rt and BKZRt. Lat-Rt is used to automatically and/or interactively define bed boundaries using any user defined curve, and interpret the Rta from lateral log curve based on AO spacing and bed thickness relationships. BKZ-Rt uses the output of Lat-Rt, with up to six interpreted lateral log (Ra) curves, hole diameter (Dh) and mud resistivity (Rm), to compute true deep resistivity (Rt), invaded zone resistivity (Rxo), and diameter of invasion (Di). Each module uses ASCII or LAS files as input. The BKZ-Rt program suite was developed specifically for the interpretation of Russian Lateral Logs, although it is applicable to any Lateral Resistivity logs. The program includes chart look-ups for Russian lateral log charts for differing Rxo/Rm and Di/Dh ratios. The BKZRt program finds the best fit chart for each bed's invasion profile. Additional charts can be digitized and can be added to the chart set. Lateral log values and AO spacings from multiple tools are used to determine the proper Rxo/Rm and Di/Dh chart, and the program calculates the degree of fit to the chart. The average Rt, Rxo, Di, chart used, number of curves that fit that chart within specified parameters, the Rt values calculated for each tool, and a depth filtered average Rt are output for each depth.

Rt-Pro & iMod (True Resistivity Profile Generation & Induction Log Forward Modeling)
Software Description: 
RtPro is used to create a true resistivity profile for a section of log, using the induction log and a bed picking curve such as the density, neutron, sonic, gamma ray, microlog, or other log with good vertical resolution. The resultant profile is used to model the induction log response, computing a �virtual� induction log. The iterations are performed while adjusting the true resistivities of individual beds until the �virtual� induction log matches the measured induction log. Results of the modeling program can be displayed using the RtPro program to compare the measured induction resistivity to the computed induction resistivity. The user can edit bed positions, resistivities and limits to improve the resistivity profile, producing a model that results in a better induction log match while preserving the representation of geology.

DigiLog (Commercial Grade Well Log Digitizing)
Software Description: 
DigiLog is a graphical PC based program for digitizing and editing wireline logs. Curves display on the screen while digitizing, or editing in primary or multiple backup modes, linear of logarithmic scales, with or without linear interpolation. Digitizing parameter are set in "pull down" windows. Parameter sets can be saved for future use and reference. The digitizer cursor or keyboard keys can be used to make menu and digitizing selections. DigiLog uses any digitizing tablet that sends data as an ASCII string in a continuous mode. Perviously digitized data can be edited graphically, or with the keyboard using the unlimited file size text editor. Screen display is paged by a user definabledepth range to show detail as curves are being digitized. Curves can be digitized from the top down, or the bottom up (for right handed stylus digitizing). Logs with curved baseline tracks and stretched depths can be digitized accurately using the curved track correction feature. Digilog can be set to digitize only inside of the track boundaries with backup curves, or outside of the track boundaries.

VolDig (Volumetric Calculations with Digitizer Planimetering)
Software Description: 
VolDig uses a digitizing tablet to planimeter contour maps, calculate areas within contours, calculate volumes represented by multiple areas, and calculate oil or gas reserves within those volumes. Contours are displayed on the screen as they are digitized. Reports are available for each volume or area planimetered showing the areas, volumes, input parameters, and calculated values. Calculations may be recomputed with different parameters if desired. VolDig can be used with any digitizing tablet that sends data as an ASCII string in a continuous mode. The program VDSETUP.EXE is used to configure the program for the digitizer being used.

SRE (Statistical Reserve Estimates)
Software Description: 
SRE computes reserve probabilities based on Monte Carlo simulation with statistical distribution curve procedures and outputs to an ASCII file. Minimum, most likely and maximum values of area, thickness, porosity, water saturation, formation volume factor, and recovery efficiency are used by the program to determine probability distributions of each of these variables. Probability distributions type is selected as triangular, linear, or variable beta function. Reserves probability distributions are computed using Monte Carlo simulations of the input distributions, and output to an ASCII file.<-p>

AI (Acoustic Impedance and Synthetic Seismogram Program)
Software Description: 
The AI program filters and re-samples the digitized logs in time, computes time scale acoustic impedance, and creates synthetic seismic traces. Check shot surveys or sonic travel time, or both can be used to define the depth time relationship. T/D charts can be generated as well as synthetic traces using user defined wavelets.

Rugose (Wellbore Rugosity Computations using Caliper Logs)
Software Description: 
This program computes a rugosity curve from the caliper based on the standoff of a tool (or pad) excentered against the wellbore wall. The tool or pad length is user defined. This program can be used to generate automatic baseline shifted curves.
