Abstract
The acquisition of quality samples from heavy oil reservoirs can be especially critical. It is frequently the case that in these<br>environments the quality of the oil is the single biggest reservoir risk. Therefore a valid fluid sample where accurate<br>measurements of parameters such as gas oil ratio and viscosity can be made is crucial. These sample can be acquired with<br>production tests but, as in many reservoir environments, it is often desirable to acquire these samples with formation tester<br>(WFT) tools.
