Advanced compositional gradient analysis
Complex fluid gradients while typical in gas condensate and volatile oil reservoirs, can also be present in in heavy oils reservoirs. SPE 115429 titled “Advanced Compositional Gradient Analysis” and presented at the recent SPE Annual Technical Conference and Exhibition in Denver, Colorado, discusses a new method to account for non-linearity in pressure gradients due to varying fluid density which is directly applicable in heavy oil reservoirs.
Improving reservoir characterization using accurate flow-rate history
This paper recently presented at the September 2008 SPE ATCE, presents results from field tests of multiphase flow meters in carbonate reservoirs producing Arabian heavy oil.
Providing answers for un-testable wells
This SPE article co-authored by Schlumberger and Repsol YPF published in the May 2007 issue of Offshore Magazine, describes an approach combining a DST and TCP work string with an ESP in the testing and completion of heavy oil wells in Peru.
ESPs Take on Heavy Oil
At a recent SPE-sponsored technical conference, Suncor Energy completions engineer Fernando Gaviria discussed the role and challenges of high temperature ESPs in SAGD heavy oil recovery.
Multiphase flow metering for SAGD
This Hart E&P article features Schlumberger's first ever application of multiphase flow metering technology for steam-assisted gravity drainage (SAGD) wells.
Planning and predicting waterflood results in heavy oil
This SPE paper presents research and modeling predictions for waterfloods in viscous, heavy oil environments.
BBC radio program covers in situ combustion
A BBC program scheduled to run the week of August 11th will feature an interview between BBC's Quentin Cooper and Professor Malcolm Greaves of the Improved Oil Recovery ResearchGroup at the University of Bath about in situ combustion and its ability to increase heavy oil recovery.
Canadian Heavy Oil Association June newsletter
The CHOA June 2008 newsletter has has an interesting interview with Canada's Director of Energy Products and Services for the Industry Development Branch focusing on heavy oil and other unconventional oil recovery.
Zonal isolation modeling and measurements
This SPE paper explores new approaches to measure and model the mechanical durability of flexible cement systems in high temperature environments common in heavy oil recovery.
A Systematic Approach to Hostile Environments
Schlumberger's Ashok Belani, Chief Technology Officer, and Steve Orr, President Artificial Lift, discuss adopting a standardized HP/HT classification system to enable improved market definition and facilitate industry communication.
Integrated decision management
This evaluation and decision making process could have application to heavy oil field development.
