This paper summarizes results to date of implementing i-field projects in selected assets in Chevron's San Joaquin Valley Business Unit (SJVBU) in California. The i-field projects include collaborative environments to transform operational processes at a basin-wide or asset level remote collaboration and visualization has been implemented to help execute reservoir management and major capital project targets reliably and efficiently in the field. Successful asset prototypes are standardized and replicated across the business unit. The results to date demonstrate business value and take-up of the technology and processes by oilfield operations.
The major producing assets of Chevron's SJVBU are shown in red in Figure 1. SJVBU production in 2007 averaged over 220,000 barrels per day from approximately 15,000 producing wells. Approximately 83% of the production was heavy, 10% light, and 7% gas. The heavy oil is generally recovered through thermal operations, while the light oil is produced by waterflood.
Unneland and Hauser (Reference 1) described the beginning of Chevron's digital oilfield program called "i-field??. Ouimette and Oran (Reference 2) summarized the use of decision support software, integrated with improved instrumentation, workflow automation, and data architecture to enable more reliable and efficient field operation and execution of reservoir management targets at San Ardo within SJVBU.
i-field has become critical to SJVBU's quest for operational transformation, in pursuit of a vision to:
Operate from a centralized asset decision environment where the application of smart oilfield technologies result in industry leading margin performance
Integrate reservoir management with operations
Automate routine decisions by artificial intelligence
Create a highly virtual organization where innovation and collaboration efficiently move ideas to applied technology
