NLREG
NLREG is a powerful statistical analysis program that performs linear and nonlinear regression analysis, surface and curve fitting. NLREG determines the values of parameters for an equation, whose form you specify, that cause the equation to best fit a set of data values. NLREG can handle linear, polynomial, exponential, logistic, periodic, and general nonlinear functions. Unlike many "nonlinear" regression programs that can only handle a limited set of function forms, NLREG can handle essentially any function whose form you can specify algebraically. NLREG features a full programming language with a syntax similar to C for specifying the function that is to be fitted to the data. This allows you to compute intermediate work variables, use conditionals, and even iterate in loops. With NLREG it is easy to construct piecewise functions that change form over different domains. Since the NLREG language includes arrays, you can even use tabular look-up methods to define the function.

GEO SUITE
It is a versatile application for creating an infinite variety of user-defined plot presentations. Whether it be well proposal charts, well summary logs, well development charts, drilling time charts, core analysis plots and gas ratio logs, GEO can cater for every aspect of your drilling operation. Templates provide automation that can plot curves and make calculations directly after a data file is loaded, saving valuable time. Templates can also automatically present prognosis data from the well plan view for guidance and comparison of planned vs actual. Open ODF files sent by the wellsite to view the latest data and interpretations. Update correlations using GEOXSection, update well planning logs and provide geological data and log imagery to drilling and subsurface teams for key decision making.

Tecplot RS
Tecplot RS is an integrated visualization and analysis software tailored for oil and gas reservoir engineers. It facilitates the management and interpretation of reservoir simulation data through comprehensive XY plots, 2D cross-sections, and 3D grid visualizations. The platform supports data import from various simulation sources, enabling users to efficiently organize results, validate reservoir models, and effectively communicate findings across teams. Recent updates, such as the 2023 R1 release, have introduced features enhancing the assessment of history match quality by allowing the creation of selection sets based on deviation bands. Additionally, the software now supports the visualization of negative values in stamp plots, aiding in the analysis of fluid behavior trends within reservoirs. With a user-friendly interface, Tecplot RS ensures a short learning curve, complemented by full technical support and free online training.
