Up one levelExpert Viewpoint - Logging in heavy oil
Frank Shray, a Petrophysics Advisor, has been with Schlumberger for over 26 years. His experience in this discipline spans every wireline and logging while drilling measurement type and environment as well as seismic, open- and cased-hole logging. Shray is currently the petrophysicist domain champion for the company’s wireline activity. In this, the first of a two-part interview, Shray, explains wireline tools, how they work and, what you can expect from Schlumberger in terms of “tool synergy”.
Asphaltenes, Heavy Oils, and Petroleomics
A just-published book promotes a new paradigm in reservoir understanding.
Expert Viewpoint with David Hin-Sum Law
In the first of two interviews, David Hin-Sum Law, Heavy Oil Technical Director, Schlumberger Reservoir Fluids Center, based in Edmonton, Canada, talks about the heavy oil industry in general, how the industry has recently come of age and the various challenges it still has to overcome.
Heavy-Oil Reservoirs - Oilfield Review Autumn 2002 (2.29 MB PDF)
Vast quantities of heavy oil are trapped in shallow, accessible reservoirs, but are difficult to extract. Producers involved in heavy-oil recovery face special challenges in producing the high-viscosity crudes, but are finding some success by applying both traditional oilfield methods and new technologies invented for the heavy-oil sector. This article reviews some of the properties of heavy oil and describes drilling, logging, completion and stimulation techniques that help make heavy-oil reservoirs profitable assets.
Keys to Heavy Oil: Characterizing fluids and the reservoir
By Shawn Taylor - Success with heavy oil depends as much on understanding the fluid properties of the reservoir as it does on knowing the geology of the reservoir itself.
The Road to Heavy Oil Success
Heavy oil development presents a high level of complexity throughout the life cycle. Most unconventional production methods bear high upfront costs. Operating costs are likewise often higher than with conventional crude production. The market for products is traditionally limited, the contract terms are difficult, and rebates may be nonexistent; these are also all concerns for those considering, or already producing, heavy oil.
