Expert Viewpoint on fluid analysis in heavy oil
Don't miss our Expert Viewpoint article on asphaltenes, compositional gradients, flow assurance and other fluids related issues pertaining to heavy oil, with Oliver Mullins, Schlumberger scientific advisor and wireline reservoir domain champion.
Electrically enhanced oil recovery
Deloro Resources Ltd. in Vancouver Canada recently completed a pilot using electrically enhanced oil recovery (EEOR) technology.
Planning and predicting waterflood results in heavy oil
This SPE paper presents research and modeling predictions for waterfloods in viscous, heavy oil environments.
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.
Dielectric dispersion applied to heavy oil
A new-generation dielectric tool that is applicable in heavy oil environments is described in SPE article 116130.
Heavy oil recovery with overlying gas cap
SPE/EAGE Reservoir Characterization and Simulation Conference presentation that discusses the modeling of heavy oil recovery where there is an overlying gas cap.
Integrated decision management
This evaluation and decision making process could have application to heavy oil field development.
The use of 4D seismic in managing heavy oil field
This article describes the benefits of using 4D seismic to manage and optimize the Marlim heavy oil field of the Campos basis of offshore Brazil.
Alberta Energy Reserves 2006 and Supply/Demand Outlook
The Alberta Energy and Utilities Board (EUB) issues a detailed report providing information on the state of reserves, supply, and demand for Alberta’s diverse energy resources including its vast heavy oil crude and bitumen reserves.
New WellWatcher fiber optic technology for heavy oil recovery
At the World Heavy Oil Congress in Edmonton, Schlumberger introduced its new WellWatcher BriteBlue harsh environment multimode fiber and WellWatcher Ultra distributed temperature acquisition systems.
Schlumberger opens technology center in Calgary
Schlumberger inaugurated a new oilfield technology center in Calgary, Alberta. The state-of-the-art center will work directly with oilfield technical teams and regional research facilities to help customers increase heavy oil production, reduce technical risk and minimize environmental footprint.

Economic downturn impacts heavy oil development
In our new feature article, Petroleum Africa interviews Kambiz Safinya on the impact of the economic downturn on the development of heavy oil, and reviews some of the new technologies that are making heavy oil recovery possible.
Evaluation of high rate artificial lift in Oman's heavy oil fields
In the northern region of Oman, PDO operates a heavy oil field produced from naturally fractured carbonates. In order to increase and extend production, various thermal EOR methods combined with advances in artificial lift are being evaluated.
Energy balance in steam injection projects
SPE Paper 121489, "Energy Balance in Steam Injection Projects Integrating Surface-Reservoir Systems", presents a workflow to analyze the integration of surface and reservoir systems for SAGD that potentially better estimates energy transfers in the various components of the system to enhance both the oil recovery and the economics of the project.
