Many reservoirs of interest include heavy oil. In such reservoirs, parti at normal temperatures, many instruments commonly used for formation evaluation may not be able to distinguish between heavy oil and bound water in the formation. Passive or active heating is used to elevate the temperature of the...http://www.google.es/patents/US6755246?utm_source=gb-gplus-sharePatente US6755246 - In-situ heavy-oil reservoir evaluation with artificial temperature elevation
