The purpose of PRODML is to enable increased innovation in the composition of optimization solutions for an increasingly complex production systems while reducing cost and risk. This translates into enabling the development of plug compatible service components and associated clients by energy sector vendors as well as energy companies. PRODML forms a framework within which energy companies can configure and achieve simple or complex processes related to operations, optimization, reporting, and/or information management. The PRODML Standards were developed by Energistics and the PRODML Special interest Group, which is comprised of energy companies and vendors and facilitated by Energistics. The PRODML Standards Version 1.0 were released in November 2006 and focused on production optimization processes that consider activity starting from the reservoir-wellbore boundary and progressing to the custody transfer point and for production optimization recommendations that can be put into effect within one day. The nature of Version 1.0 was based on the widely used Energistics family of drilling standards, WITSML, that was first published in 2001. PRODML reused many of WITSML's data structures and interface operations. PRODML Version 1.0 was also based on an extension to WITSML developed in 2004 to support production reporting. It adopted current best practices for interface definition as defined by IT industry organizations, such as WS-I and W3C. This version of PRODML (Version 1.1) was released in Feb 2009. It represents an incremental evolution of Version 1.0 and includes enhancements derived from the experience of adapting PRODML Version 1.0 for use in six pilot implementations during 2007.

Introduction to PRODML PRODML is an industry initiative to provide open, non-proprietary, standard interfaces between software tools used to monitor, manage and optimize hydrocarbon production. Applications currently used to support production workflows are available from multiple vendors. However, they cannot be integrated easily because they typically have their own data structures and incompatible designs. PRODML provides data specification standards for defining and sharing data commonly used in production workflows and software design standards for invoking application functionality as required. Operators and vendors will both benefit from these standards. The former are assured of greater compatibility between vendor products, improving ‘plug-and-play’, or interchangeability of individual software components and reducing the cost of integration. The latter can more easily integrate their products into customer architectures reducing development and delivery costs. Ultimately the industry will benefit from improved standards that allow resource holders, operators, customers and regulators to share production information more readily and more reliably. PRODML focuses on production workflows from the reservoir-wellbore boundary to the custody transfer point, and on production optimization decisions that can be effected within a day. PRODML is a logical extension of the more mature WITSML standard (Well Information Transfer Standard using XML) widely used to transfer drilling information. The intention is to maintain alignment between these standards. The first version of PRODML was developed within approximately one year as a result of a focused, collaborative effort on the part of five oil companies, eight software suppliers and a petroleum industry standards body (the PRODML Workgroup): Sponsoring Oil Production Software Petroleum Industry Companies Companies Standards Organization BP Halliburton POSC ChevronTexaco Invensys ExxonMobil OSISoft Shell Petroleum Experts Statoil Schlumberger SenseIntellifield TietoEnator Weatherford Three use cases were used to develop the initial implementation of the standard: • Gas Lift Optimization • Optimizing Production from free flowing wells using real-time measurements and network models • Field Wide Optimization based on real-time measurements, network models and production forecasts Four pilot tests, based on the above use cases, were conducted using field data provided by the operators, and applications and test code implementations of the PRODML standard provided by the software companies.
