From simple workflows such as quality checking log data to performing complex tasks of multi-zone, multi-well petrophysical analyses, Interactive Petrophysics is ideal for both petrophysicists and geologists.

       Sasha software

       The SASHA program evaluates shaly sand reservoirs, and provides effective porosity, water saturation, clay and silt volumes. Sasha analysis can also determine the relative permeabilities. This is an industry standard shaly-sand analysis model.

       CORAL software

       CORAL Analysis provides an accurate detailed description of reservoirs and mixed lithology. Its primary use is in the evaluation of formations, which contain shale, sand, limestone, dolomite, anhydrite, and gypsum. The software will provide determination of shale content, cross plot lithology (sandstone-limestone or limestone-dolomite), anhydrite content, porosity, secondary porosity or gypsum (if an acoustic log is available), permeability and water saturation.

       Ultra software

       ULTRA is one of the most famous software in petrophysical analysis. This program is a set of software modules, designed to process wireline logs. ULTRA program is based on an optimization approach, computing the most probable parameters from the set of logs and local knowledge of the logging environment. The following Log Analysis Models are built in: Shaly Sand, Sand-Lime-Dolomite with up to six other minerals and clay, Igneous and metamorphic reservoir model.

      Basroc software

     Reservoir model – two porosities and two permeabilities: Macrofracture zones characterized by macro-fracture systems, distributed directionally with hydrodynamic permeability. Microfracture zones distributed along surfaces of macrofractures

     BASROC is an advanced multi-mineral log analysis program for basement rock. It computes the most probable formation mineralogy and total porosity, open porosity using a multi-log, least-squares inversion technique. It is particularly valuable in areas of mixed lithologies, special minerals and two porosities systems. Grade porosity by filtered method. Calculate fracture porosity by looped technique.

       Fullwave software

       FullWave software is a waveform diagnostic program. It can be used to display waveform data in time and frequency, perform frequency filtering, and for estimation compressional, shear, stoneley slowness using semblance processing from wave acoustic processing program and attenuation of Stoneley wave energy.

       Beside that, FullWave module allows for Anisotropy Analysis

     2.  Casedhole Data

      Processing and interpretation for PL data


  • Production logging surveillance has given the reservoir engineer a powerful tool in the drive for refined reservoir characterization. Emeraude is now used by all the major service companies, many independent operators and service providers. Emeraude is seen as the industry standard allowing a common platform for communication and interpretation between service companies and operators.
  • From vertical injectors to horizontal or highly deviated multiphase producers, Emeraude provides a comprehensive and intuitive set of tools, to produce results from the log data from simple through to the most sophisticated tool strings. KAPPA remains committed to the ongoing development of the industry standard PL interpretation package by remaining in close contact with tool manufacturers.
  • Emeraude offers a full range of flow models from single to 3- phase flow. Specific models are provided to handle flow re- circulation as well as flow through standing water columns.
  • Rate calculation is treated as a minimization problem and solved using nonlinear regression, offering full flexibility in the type and number of input measurements. Interpretations can be run from any number of sufficient inputs including: spinner apparent velocity, density, pressure gradient, capacitance, holdup of any phase, velocity of any phase, rate of any phase, and temperature. Recent additions permit multiple measurement of the same type.

        Cement bond evaluation

          The basic reasons for casing a well are to provide wellbore stability, zonal isolation and control of well fluids. Cement provides mechanical support for the casing and the isolation seal between the casing and the formation. Without effective isolation there is a risk of communication between zones, water infiltration and leakage to the surface.

          The L&TD’s available measurements from 4AK-1T, Sector Bond, BCDT and CAST-V tools are used for cement bond evaluation.

          Casing and Tubing inspection

          The productive life of an oil well can be reduced by the condition of the well itself. Deterioration of the casing or tubing can be caused by corrosion, unintentional damage during drilling and intervention or formation movement. Scale build-up can also reduce production. Remedial work can be minimized with exact knowledge of a well's condition. The operator can receive early warning of a potential problem and obtain data for determining a specific restoration program by running the casing inspection suite.

          The L&TD’s available measurements from Max-Min or Multifinger Calipers and CAST-V tools determine the condition of the casing or tubing within a well.

          MITView software

  • One of the most effective ways of understanding the condition of a well is to produce 3D images. To achieve this, we use a package called MITview.
  • This powerful presentation package uses the ASCII files of data recorded by an MIT to produce 3D images on a PC screen.
  • While views down the well are very informative, MITview can be used to allow the operator to look at features from different directions. Full control of the displayed image allows it to be angled, rotated, lengthened etc.

       MITPro software

       MITpro software is used to process raw data from the Multifinger Imaging Tool (MIT). The MIT is used to detect changes of the internal diameter of tubing or casing; tool data is normally output as a log curve for each finger, which can be a significant amount of data to evaluate manually. The MITpro program has been developed as an aid for data processing and analysis.

         Tool data is read by the MITPro software to determine the metal loss, scale build-up or damage in a completed well. Collars can be automatically detected, then the data for each joint of casing or tubing is processed and the percentage change of internal diameter from nominal is calculated. The analysis overview lists all potentially damaged pipe joints and a picture representing the pipe cross-section for each one can be generated to show the internal diameter change from nominal.

        Well card software

  • WellCAD is PC based composite log package, which combines comprehensive graphic editing mechanisms and data processing tools.
  • Combining technically excellent display, editing and analysis capabilities for well data, WellCAD has become the standard log composite software in the Mining, Oil&Gas and Geotechnical society and is used in a wide range of applications.
