The latest release of the Tigress 5.0 platform, version 5.0.3, has been distributed to the Geotrace Tigress user base. This release introduces over 100 changes to the product, including enhancements and fixes across the Tigress range. The 5.0.3 database runs on Oracle 9.2.
Key areas of improvement in Tigress 5.0.3 include data management, data handling, the geoscience applications and remote support.
Data management and handling
A significant amount of development work has gone into the data management aspects of the product, which reflects the renewed interest of users and the wider industry in secure and efficient data handling. We have added more functionality to the data handling routines and broadened the breadth of data types that can be moved in and out of the database using the powerful TIES interface.
Project management now includes a quick check project back-up routine that identifies any changes to a backup file, making multiple project administration much simpler. Similarly, there is a new scan utility to assess consistency of log traces and search for duplicates in a project.
Other data handling improvements include:
- exporting seismic data in either time or depth
- choose to resample or leave unchanged log data in bulk well data exports
- extended Petrel and Zmap data file handling
- export of seismic faults with or without the associated survey data
- better LAS file handling, including non-standard keywords, and LAS to PBAscii format conversion.
Geoscience

Over 50% of the developments are in the geoscience applications. Again these introduce additional functionality or address areas where users had provided feedback on usability and performance. Some of the changes include:
- seismic display capabilities have been increased to handle significantly larger seismic data sets
- composite seismic displays now handle different sample increments using the smallest of the different increments loaded
- petrophysical interpretations using the Archie equation now check for sensible input values
- better handling of merged log traces across petrophysical interpretations
- improved clipping at plot edges on mapping hardcopy
- save detailed saturation mapping models
- improved multi-well decline curve analysis handling.
Remote support

One of the key developments over the last year has been the rapid deployment of remote support as an additional support mechanism for the user base. The security and improved reliability of the Secure Shell (SSH) connections, using standard Internet bandwidths, means Geotrace can now provide clients with quicker support and hands-on support without the need for on-site visits. This, in turn, is opening up additional support service areas, with clients now outsourcing aspects of data management and interpretation to our team of in-house Tigress experts.
One of first sites to take advantage of the new release was the Ministry in Baghdad, which used a fully remote service facility to upgrade the Tigress platform to this latest version.
Laptop users, who are frequently on the road, are also making good use of remote support options, for anything from data loading to interpretation support on new functionality.
