Interpretation tools

 

We offer a comprehensive array of interpretative software products to help multi-discipline asset teams to rapidly evaluate field prospectivity, analyze drilling prospects and design development and production programs.

The Tigress application suite, combined with the Project Data Store (PDS), delivers a robust project data management and interpretation environment, which reduces project cycle time and cost while increasing project integrity and staff productivity. It sounds grand, but in short what it means is that you can continue to work in traditional integrated teams or on your own, where you have to cover many bases at once. The traditional application disciplines are outlined below.

Products

Tigress Geophysics

Tigress Geophysics provides a complete set of easily accessible applications for the interpretation of 2D and 3D seismic data, and the generation of synthetic seismograms to tie in geological models. These tools, coupled with 3D visualisation and time/depth modelling, provide an integrated approach for the geoscientist. Results of the interpretation are saved to the Project Data Store for use in the other Tigress modules.

Tigress Geology

Tigress Geology allows you to model the chrono, litho and fluid stratigraphy of the reservoir, using multi-well, multi-level zonations, and correlation and cross-section interpretations. Tigress Geophysics, Tigress Petrophysics and Tigress Mapping data are integrated to accurately model the well and inter-well areas.

Application hot links with Tigress Petrophysics applications, Cross Plot, Histogram and Cluster Analysis can be used to define finer facies and lithology zonations using core and log data. Zone thicknesses can be generated from the finished zonation and then passed to Tigress Mapping along with zone top and bottom depths for gridding as part of the structural modelling process. Results of the interpretation are saved to the Project Data Store for use in the other Tigress modules.

Tigress Petrophysics

Tigress Petrophysics allows you to characterize the reservoir by analysing log, core and formation test data. The module provides a comprehensive set of applications for log and core data manipulation and correction, parameter calculation and log analysis for both open- and cased-hole logs. Both input and output data can then be zonally averaged for use in mapping. An automatic audit trail records all processes, so that analyses can be easily rerun using the latest input data or parameters. Data templates and pictures ('snap shots') mean that loading and retrieving data sets is simple and quick.

Advanced reservoir characterisation programs are available to assist in zonal analyses, and the user can build, or link to, customised programming routines for further analysis.

Tigress Mapping

Tigress Mapping allows you to model the structural and lithological properties of the reservoir spatially. Geophysical, geological and petrophysical data can all be integrated to construct an accurate reservoir volumetric model. Colour basemaps can be built easily, incorporating spatial data from across the PDS. Complex arithmetic or logical operations can be performed on data using standard or user defined equations, the results of which can be used in the volumetric model. Volumetric calculations can be performed on the model with results being reported in a choice of units and on an area by area basis. The static model can be passed to Tigress Simulation as the basis for the fluid flow simulation model.

Tigress Engineering

Tigress Engineering lets production engineers monitor the construction and production history of a well, and reservoir engineers model reservoir behaviour using pressure test measurements and the results of laboratory fluid experiments. Results from pressure analysis and black oil and compositional fluid analysis are used directly within Tigress Simulation to model fluid flow.

Tigress Simulation

Tigress Simulation provides a wide range of analysis techniques for black oil, compositional and EOR simulation including thermal modelling, with gas condensate and dual porosity options. Both IMPES and fully implicit time stepping methods are supported for 1D, 2D and 3D models. A unique strength is the use of the integrated project database as the focal point for the compilation and management of the sequence of models required in a simulation study. No keyword files are necessary as all data is stored in the database. The architecture of the Tigress Simulation module allows the use of third party simulators such as Eclipse, Chears, SURE and Falcon MPP.

Tigress Production Data Management and Analysis

Tigress Production Data Management and Analysis (PUMA) is used for the analysis, manipulation and easy visualisation of recent and historical production data. The application performs all of the typical objectives of reservoir performance analysis and forecasting, including:

  • estimation of original hydrocarbons in place
  • analysis of past and present performance
  • prediction of future performance under current conditions
  • estimation of reserves and recovery rates under various conditions
  • updating of analysis with new data during life of field.

Advanced plotting and reporting tools provide excellent templates for the creation of high quality output.
