GOWProp calculates gas, oil and water PVT properties based on user selected method: - Gases: Natural Gas, Air and Nitrogen; - Liquids: Oil, Water, Methanol, MEG, DEG and TEG; Gas properties include: Density, Compressibility, Z-factor, Viscosity,Isentropic coefficient, etc. Liquid properties include: Density, Compressibility, Bubble point pressure (oil), Viscosity, Solution Gas-Liquid ratio (oil and water), Specific heat, etc.

BeamBoy
BeamBoy is a free engineering utility for calculating stress and deflection of structural beams under load. May also be used for shafts. BeamBoy is menu-driven and intuitive.

Copan Pro
Copan Pro enables you to calculate coordinate geometry (COGO), process field surveys, adjust map traverses, perform map/deed closure checks, calculate areas and perimeters, transform coordinates, import/export Ascii files, and draw lines and symbols.

Astra R-Nesting
Astra R-Nesting system provides entry and storage of information about orders and materials, automatic and interactive nesting, utilization of rests, printing nesting plans and specifications, estimation of cost of works carried out.

Orifice
Orifice calculates size, flowrate or pressure drops for gas and liquid orifice meters based on ANSI/API-2530-1991, Part 3 (AGA-3) or the International Standard ISO-5167-1:1991. Customary or SI units.

OilProp
OilProp is designed to assess the core thermalphysic properties of oil and its derivatives necessary to solve transportation and processing tasks, with the minimum volume of input data.
