1.4.1 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 WITSML, RESQML (earth modeling), and PRODML (production 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).

For a list of the main components of the Energistics CTA used by WITSML, see 1.3.2 Energistics Common Technical Architecture Resources. For an overview of CTA, see 2.1 CTA: Main Components and What They Do.
