Chevron PRODML Pilot Activities

Background
Chevron’s pilots have a few common characteristics:
• Using a large brownfield waterflood field as a basis
• Concentrating on water handling
• Providing a number of vendor opportunities
• Developing in-house capability
• Expanding in scope over time

Background (cont…)
2006: Compared Field vs Facility forecasts and notified operator. Stress tested the standard with multiple 700 well data calls in a single process model
2007: Combined multiple elements – forecasting, real time capacity management, field network optimization and cross-functional visualization
2008:
A: Continue to refine pilot to plug and play pieces (8) that are “fit for purpose”
B: Testing new WG07 functionality (SAM-Shared Asset Model, extensibility)
C: Working with other PRODML members on NOJV reporting
D: Preparing to test the use of WITSML data for well modeling

Characteristics of a Workflow
A workflow …
• should systematically organize components;
• should define roles, for operator personnel, for vendors and for automated systems;
• must have endpoints that effectively define the purpose of the process;
• needs defined information exchanges (such as those defined as part of the PRODML Standards);
• needs visibility of information flow;
… and looking ahead to results, a workflow:
• leads to achievable results;
• has a process that can be documented and learned;
• enables measurement of results.
