Practical solutions for reservoir data
and information management
Increases in production result from system implementation
Shell Nigeria has refned a system that makes acquired wells, reservoir, and facilities (WRFM) data useful for better under- standing of reservoir response for effective well, reservoir, and facility management reviews; to provide a basis for identifying short-term oil and gas generation (STOG) opportunities; as an
aid to meeting statutory requirements; and to improve calibrations of
integrated models to increase recovery and reserves totals.
Integrity and assurance of the acquired data are important to the
business and require practical solutions. In Shell Petroleum Development Co. Nigeria (SPDC), data and information management solutions are strengthened, especially within the Wells and Reservoir
Facility Management team. This has led to signifcant and consistent increase in production, reduction in deferment, and a slowing
in the oil decline rate.
The process of data acquisition and analysis involves technical
staffers from SPDC and vendors. There is continuous monitoring to
ensure all approved company procedures and minimum standards
are strictly adhered to. For assurance process, Shell WRFM value
loop is a reference point where models are generated and interpret-
ed considering all the possible uncertainties, threat to production,
and asset integrity.
Because data quality is critical, each asset has a comprehensive
WRFM data acquisition plan, detailing the procedure, cost, data defnition, and data value owners. The Information Quality Metrics que-ries and Web-based visualization tools help asset teams recognize
data quality issues and quickly resolve them.
Business drivers were mainly to enable the petroleum engineering function to arrest production decline, maximize oil production
from existing assets, accelerate hydrocarbon maturation, and reserves replacement through value-adding subsurface data management practices by introducing
ft-for-purpose new technology, integration, and collaborative tools; simplifying the integrated review
processes; and improving the availability and visualization of wells, reservoir, and facilities data.
Integration and visualization of key data types
required for WRFM reviews are the key objectives,
hence the following methods are used:
• Defnition and scoping of data quality/gap is-
sues
• Scoping and project defnition of data cleanup
projects
•Embedding of data managers in day-to-day
business process
• Clear ownership and data accountability by the
business
• Adoption of practices worth replicating (PWR)
across the operating units
• Engagement of various disciplines in value-
added IM/DM propositions
• Creating product user/developer interface.
