New High Temperature Heavy Oil Testing Cell
Heavyoilinfo.com spoke to Tara Engel, fluid analysis product champion at the Schlumberger Oilphase-DBR technology center in Edmonton, Alberta, about a new heavy oil PVT laboratory testing cell that has improved mixing capabilities and is rated for temperatures up to 250 degC. Tara Engel is a petroleum engineer, currently focused on the Schlumberger RealView live solids deposition cell and heavy oil flow assurance measurement services.
Clear Reservoir Understanding: Viscosity Analysis
Improved Methods for Estimating the Viscosity of Heavy Oils from Magnetic Resonance Data, by Burcaw, et al. Copyright 2008 is held jointly by the Society of Petrophysicists and Well Log Analysts (SPWLA) and the submitting authors.
Expert 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.
