PPDM is the data model published by the PPDM Association (formerly the Professional Petroleum Data Management Association). Many operators know the name; fewer have put it to work. This is the short version. What PPDM actually gives you goes deeper, including what the model leaves to you.
The Problem PPDM Was Designed to Fix
Upstream oil and gas has a well-identity problem. A single wellbore might appear differently in a SCADA historian, a land management system, a production database, and a financial ERP. Different vendors built these systems at different times, with different assumptions about what makes a well identifier unique.
When you try to join data across these systems to answer a question as simple as “what did this well produce last month, and what was the revenue?”, you hit a wall. The identifiers don’t match. Someone has to reconcile them by hand.
PPDM began as a public, non-proprietary data model for petroleum data. It gives well, land, production, contract and related business data a common structure that disparate systems can map to.
What PPDM Actually Defines
At its core, PPDM provides:
- A structure for well identity. It separates the well, the wellbore and the completion, and the association maintains the US Well Number standard for identifiers. It does not make your historian or ERP carry the same identifier. That mapping is still yours to build.
- Standardized entity relationships. How wells relate to licenses, stratigraphic units, completions and surface locations. These relationships are defined once, not defined again by every system that touches them.
- A shared vocabulary for lineage. Where a data point came from and when it was recorded is something a PPDM-aligned design is expected to track. The model supplies the places to record it; your pipelines have to fill them in.
Why Some Operators Don’t Have It
PPDM alignment isn’t free. It requires deliberate architecture decisions at the point of data ingest, not a cleanup exercise after the fact. Many operators built their data infrastructure system by system, vendor by vendor, without a unifying standard underneath. Why PPDM implementations fail covers what goes wrong when that deliberate step gets skipped.
What to Expect From It
PPDM solves the schema problem. It does not decide that two records are the same well, and it does not clean your data. Before you start, decide:
- Where the well master lives. One table, one owner. A single master well table without MDM shows one way to build it.
- Which source wins when two systems disagree. Write the rule down before the first load.
- How acquired assets get onboarded. Mapping them to the schema at ingest is cheaper than rebuilding an integration later.
InFocus Data treats PPDM alignment as a forward-looking platform capability, and these are the questions we put to ourselves first.
