Open the CIPO recordAbstract From the Canadian patent
A method and apparatus for converting downhole wireline logging measurements of pressure gradient, formation pressure and temperature into estimates of petroleum fluid PVT properties unaffected by oil-based drilling mud without , the need for retrieving actual petroleum samples from the borehole for laboratory analysis at the surface. The statistical accuracy of the PVT properties of reservoir fluids are enhanced with geochemical information of the fluids expected from a given reservoir.

Why it's free to use
- Filed March 19, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 19, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 19, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
