An example of a customised DLIS, LAS and WITSML file export

5,290

Published on

Integrating E&P technical data often requires a tailored solution that simply is not available off-the-shelf. However, building a custom solution can be a costly and risky undertaking that can end in failure. This presentation, which includes links to the online demo version, shows an example of how we recently delivered a comprehensive LAS, WITSML and DLIS file export from our client’s new PPDM-based software product in around three months, on time and to budget.

  •  The export isn’t standalone, it’s an addition to an established system with many other applications. There are several companies involved and they have a way of working.The client UI code is developed by one team, required application server side services will be provided by another. The PPDM database contains the data to export.
  •  For us there are 2 aspects to the solution: mapping rules, which specify at a domain expert level how the fields etc in the source PPDM database are written to the export file formats.We did this in Excel mapping at the table and field level, using terms in the source familiar to PPDM relational model domain experts, and target terms familiar to the clients DLIS, LAS and WITSML domain experts.Somehow these definitions need to be imlpemented such that they can execute on the target system.Deployment is the provision of web services, JMS messaging and enterprise application to support the export functionality.Much of the system exists, there are 3 teams working together, they have their way of doing things. There are already Java, WebLogic application server developmehnt and admin expertise (admin ongoing), Oracle experts and client UI experts. We need to minimise the impact of the export module – minimise additional costs, installation and ongoing admin requirements.
