The Shared Asset Model (SAM) is a software system specification that enables the discovery and navigation of information about producing upstream assets. It is part of the PRODML industry standard. Using a SAM makes it possible to store and discover asset information, such as: a registry of all the components that comprise the asset (e.g., wells, pipelines, etc.) together with their identities; multiple hierarchies of such components; the nature, location, and identity of additional information about these components (e.g., well completion data), and representations of the various flow networks in which the components may be connected.

For a typical producing asset, data exists in many diverse systems, for example, production allocation and accounting, well services, well modeling, surveillance, completion data, etc. Discovering and then integrating this data can be a significant overhead and can form a barrier to the exploitation of best practices and digital oilfield (DOF) innovations. Furthermore, a producing asset is rarely static. The configuration either of the real asset or of the data systems supporting it change frequently. This dynamic nature makes the task of sustaining any DOF system reliant on data a continuous and intensive process.

A SAM acts as a gateway into asset data, presenting the user with a consistent and easy-to-navigate interface to discover details about the asset and to be "directed" to its underlying data. The specification and testing of SAM capabilities demonstrate that it satisfies the needs of many common workflows in terms of managing configuration and accessing data.

The SAM specification is expected to be widely deployed, either through a new generation of software applications or as a "façade" or gateway into existing systems. It will enhance DOF projects in terms of deployment speed, reliability, flexibility, and cost reduction over the full life cycle.
