Standards & Best Practices

The PPDM Association defines and creates standards to help oil and gas companies manage exploration and production data.

The members of the PPDM Association provide critical input and help to set the strategic direction for the organization. Under member direction, the PPDM Association has come to represent much more than the world’s leading petroleum data model. Our organization has also been instrumental in developing and introducing oil and gas data management standards that are built around business rules and best practices.

PPDM Data Model

  • PPDM 3.9 is a rich data model covering 53 subject areas, ideal for a Master Data Management solution.
  • PPDM 3.8 data model is a robust relational data model ideal for Master Data Management strategies and for business focused application development.
  • PPDM Lite is a simple data model structure that collects information most important to users of GIS systems.
  • Sample Data Sets contain data for seismic surveys, land parcels and wells, etc.

Taxonomy Dimensions

The exponential increase in information volumes in E&P means that most Oil and Gas companies are faced with rapidly growing volumes of information that is increasingly difficult to find, of uncertain value and often lacking in business context. The use of faceted taxonomies to help manage large amounts of disparate information is not new, however it has only recently been widely identified as a valuable approach for the E&P industry.

What is a Well?

Over the years, the business entity that we call a "well" has become increasingly complicated; corporate and regulatory processes have evolved to manage this increased complexity in different ways. The end result has been a mixture of systems and data sources that are difficult to integrate and use effectively. PPDM members have created a set of baseline definitions that map to entity definitions and business rules used by various organizations and departments in our industry. This creates a "Rosetta stone" framework that will allow industry to understand how well entities relate to each other.

Data Rules

The E&P business is very complex; managing data properly requires that data be understood and evaluated through business experts and expert knowledge systems. Thousands of business rules typically govern the data management operations of most E&P companies; unfortunately, these rules are rarely documented or applied consistently, making data management and integration a very difficult process.

This pilot project was a collaboration between PPDM and Energistics to determine the feasibility of mapping the PPDM Data Model and seven key objects in WITSML.

Well Status & Classification

What we refer to as well status and classification are essentially different ways of describing wells so that people can find the right well or set of wells for the purpose that they require. PPDM members have created a standard set of well status facets, along with an integrated set of plot symbols.

Well Identification

In E&P databases, every well and wellbore needs a unique identifier. PPDM supports the industry’s efforts to improve well identification systems. This responds to the increasing complexity of well construction, the rapidly expanding volumes and types of data, and the need for unambiguous exchange of well data among businesses, governments and computer systems.
