1.3.1 Energistics Common Technical Architecture (CTA)

One of the goals of digital oilfield technology is to break down domain silos in E&P workflows. In support of this goal, Energistics is working to better harmonize its domain-based standards, including PRODML, RESQML (earth modeling), and WITSML (wells, drilling, well-related operations).

Energistics is also moving towards sharing resources and establishing processes across its standards where this approach makes sense, for example, with coordinate reference systems, units of measure, and file packaging conventions. These shared resources are referred to as the Energistics Common Technical Architecture (CTA). A key factor driving the update of PRODML is the move to the CTA.

For more information on the CTA, see 2.1 CTA: Main Components and What They Do , Section 2.3 PRODML Use of CTA , and the CTA Overview Guide, which is included in the PRODML download.
