Understanding Energy Industry– Oil and Gas

By Suvradeep Rudra

PPDM Association (PPDM) is a not-for-profit organization that develops data model defines the structure and relationships of data

It maintains standards for the energy industry. With over 100 member companies comprised of petroleum businesses, data vendors, software vendors and service firms

PPDM Association provides a roundtable process to bring experts together to build useful and business-driven standards

PPDM - Public Petroleum Data Model Association(“PPDM™”)

Current version 3.8 Based on entry level SQL 92 standards PPDM can be implemented in any fully using SQL*92

database (Oracle, SQL*Server, POSTGRE and others). PPDM cover 53 subject areas 1238 tables

PPDM - Public Petroleum Data Model Association(“PPDM™”)

PPDM Lite 1.0 based on entry level SQL 92 requirements.

This model contains 79 tables that summarize important Exploration and Production information for use in a GIS

PPDM Lite 1.1 includes a greatly enhanced Well Table

PPDM light weight model

PPDM Subject Areas – Bottom up Approach

PPDM is focused on the needs of the upstream oil and gas community. The subjects included in the current production model version are:

Wells Production Seismic Land mineral rights Data management Lithology Support

PPDM - Public Petroleum Data Model Association(“PPDM™”)

Rules and guidelines that govern the development of the PPDM data model

Establish procedures for naming tables, columns and constraints

Guidelines for columns format, reference tables subject areas management

PPDM Architecture Rules

Adherence to open standards Impact on users of various data base platforms (Oracle, Sybase, etc.) Integration or modification required to existing model structures Effort needed for development or conversion of software by members Effort required for implementation or conversion of data models by

members Effect on performance, usability and understand-ability of the model Cost to implement recommendation in the model

Impact - Changes to PPDM

The structure of a table names is: SUBJECT AREA + MODIFIER1(sub-area) + MODIFIER2(grouping)...

Example: WELL WELL_PRESSURE WELL_PRESSURE_AOF WELL_PRESSURE_AOF_4PT

Data model Artifacts - Structure

Maximum of 24 characters is used for PPDM table names. Table names are singular and in present tense.

Intersection / associate tables will be named according to business usage and by borrowing from the names of the intersecting tables.

Example: WELL_TEST

Cross-reference tables created from a single parent table are named by adding an XREF qualifier to the name of the table.

Example: BA_XREF

Data model Artifacts - Structure Rules

Internal Sites Wells and related assets, areas/lands,

pools/basins, fields, stratigraphic units, Facilites, production entités, Eco-zones and

environnements Production facilites (pipelines, batteries,

compressor stations, gas plants, meters, separators, and more),

Support facilities (rigs, roads, transmission or radio towers, airstrips, an more), logistic sites

Internal sites / External site

External sites Include partners’ locations Facilities Suppliers’ locations and facilities, etc.

Internal sites / External site

Wells - Well name and desc .

Applications and Area – identifier for Application/Area

Business Associate - Person ,Company, Agency etc

Contacts – contract

PPDM lite - Tables

Land – all rights for the land and land Sale details

Licenses – all approval granted

Production – production entity

Projects – Project Details

PPDM lite - Tables

Reserves – Confidence /producing status of res volume

Fields and pools – Details of a field ,country /state

Financials – All financial components od the business

Entitlement s – Seismic Lease data entitlement

Facilities – Storage, Company, Person

PPDM lite - Tables

Exploration geophysicists and geologists get Quality exploration data

Drilling engineers also will have timely access to relevant drilling data, and therefore decisions are made with more accurate data

Production engineers can use a Single Source of Truth for production and reserves data and oilfield KPIs

Oilfield Operation are able to share well, land, maintenance and production information

Finance has single version of truth as in oilfield and ERP records, revenue recognition, reserves and less credit collection risk.
