PETROLEUM SOFTWARE TECHNOLOGIES

Petroleum Software Technologies (PST) has taken some of the most powerful new mathematical modeling technologies available in the E & P industry today and made them available to every geoscientist through a simple PC interface.

NNLAP™ Neural Network Log Analysis Program

NNLAP™ uses neural network technology to generate synthetic wireline log and core properties from the available curve data. Neural networks learn the nature of the dependency between the curves you have abundantly available and the curves you need through a carefully selected and representative set of training examples.

NNLAP™ is an empirical method which offers significant advantages over traditional methods in that it:  1) does not require a mathematical model describing the predictive relationships, 2) yields robust solutions with only a few, well-chosen training examples, 3) preserves original data variability in the neural network-constructed mathematical model, 4) will not over-predict mean values (as will linear regression techniques), 5) is interactive, and allows the operator to use his/her knowledge and experience in training and validating the neural network solution, and 6) is fast, accurate, intuitive, and easy to learn to use.

NNLAP™ will generate high-quality synthetic curves (compressional or shear wave acoustic logs, porosity logs, NMR, core permeability, etc.), but can also be used to predict rock types, facies, mineralogy, and production data.

Rt-Mod™ Automatic Inversion Modeling Software for Resistivity Logs

Rt-Mod™ is an automatic, high-speed inversion modeling program for resistivity logs. It simultaneously corrects for borehole conductivity, invasion, bed shoulder effects, and dipping beds up to 60°. It gives an accurate representation of true formation resistivity (Rt) and the resistivity of the invaded zone (Rxo) at bed boundary resolutions of less than two feet for most resistivity logs.

The forward model combines finite element analysis and an analytical solution. This results in extremely fast computation times. The forward modeling results have been validated with known standards and by more than 70 companies using proprietary data from around the world. Rt-Mod™ offers the industry the only practical method for processing large intervals and large numbers of wells in batch mode. You can process 100 feet of induction log in about 10 seconds on a modern PC.

The program currently accommodates a two curve solution for induction logs (6ff40), old ES logs (lateral and normal logs), the Limestone Lateral Log, the Russian BKZ and induction logs, Chinese logs, the MPR and ARC MWD logs, the Dual Laterolog, Schlumberger’s AIT log, and Halliburton’s HRAI log. Rt-Mod can also perform a joint inversion on up to 6 BKZ curves simultaneously.

Applications include:

• evaluating pays in thin beds

• making accurate reserve estimates

• perforating the correct zones

• acquisition evaluations

• looking for bypassed pay in thin (less than 40') beds

• equity determinations

SP-Mod™ Automatic Inversion Modeling Software for Spontaneous Potential Logs

SP-Mod™ is an automatic, high-speed, inversion modeling program for the SP log. It corrects the SP log for Rt/Rmud and bed thickness effects to produce a “pseudo-static” SP at a 1-2’ vertical resolution.  The corrected SP curve can be used to accurately predict Rw, even in formations that do not produce water samples.  By using the SPRQ (SP Rock Quality) module, the operator can normalize out the effects of changing Rw and Rmf from well to well and generate a high resolution SPRQ curve that can then be used  quantitatively to predict permeability.

 SP-Mod™ uses modeling technology similar to that used in Rt-Mod™. The forward modeling results have been validated with known standards and by more than 70 companies using proprietary data from around the world. SP-Mod™ offers the industry the only method for processing large intervals and large numbers of wells in batch mode. You can process 100 feet of SP log in about 5 seconds on a modern PC. Rt-Mod and SP-Mod intervals can be run together in batch mode.

Applications include (but are not limited to):

• evaluating pays in thin beds

• calculating Rw (even in hydrocarbon-bearing formations too tight to produce water)

• quantitatively predict permeability

It is portable, quick, versatile and easy-to-use log analysis software ideal for both geologists wanting to do a quality check of their log data and experienced petrophysicists carrying out multi-zone, multi-well petrophysical field analyses.

It is quite a radical change from the standard log analysis package in its ease of use, interactivity and speed. Its speed, versatility and interactivity mean that you can zone data and apply different methodologies graphically. Using only the mouse you can pick parameters from cross plots, histograms and log plots. The changes made to any parameter results in instantaneous re-calculation and presentation of the interpretation. This means that analysts can produce accurate results efficiently. For the more experienced user, a full range of functionality is available. This includes a module for 'Statistical Curve Analysis', applying Fuzzy Logic to predict rock property variations. The Monte Carlo module allows the user to perform a full Monte Carlo type error analysis of the petrophysics in just a few minutes giving zonal probability results (P10, P50, P90).
