“Calgary is a unique market in many respects, with the concentration of technology companies together with operating companies—a very close-knit group—and also the cross-pollination between the software and data companies and operating companies,” he notes. “We also have government regulation [Energy Resources Conservation Board] that ensured data was freely and openly disseminated, and that had a big effect in creating that culture. “This whole initiative was born in Calgary, and is now going worldwide.”
The growth of horizontal drilling has added a new layer of complexity to the PPDM's efforts.
that, in the times we are in, the ability to use a common standard data model and agreed terminology really improves efficiency and cuts costs,” he says. “Part of the strength of the organization is that oil companies come together collaboratively and work to provide an open source standard right across the world.” While the What is a Well? project is just one of several PPDM initiatives, Hood says some companies have told him adopting What is a Well? alone has justified belonging to the association. He says the distinct characteristics of the Canadian oilpatch are responsible for the direction taken by the organization.
Clarifying well status and plot symbology Building on the work in What is a Well?, the PPDM has worked toward simplicity and clarity in well status and classification. “Well status and classification is about establishing baseline definitions for how we describe wells,” says Cooper. “The benefits realized from What is a Well? have brought more companies to the table so that we can continue to improve the way we manage wells in our business.” Working with a group of sponsors, the PPDM has developed a series of 15 facets for describing groups of wells. Each facet comprises a concise definition, a set of mutually exlusive values with their own definitions and a set of qualifiers where it is necessary to break down the facet values further (e.g. Facet = Fluid, Value = Oil, Facet Value Qualifier = Crude). A set of map symbols were then generated by combining the fluid type and wellbore status facets through a matrix. By taking this approach, there is logic to the map symbol set that will lead to improvement in communication and interpretation.
