Challenge: Efficiently collect
ultralow-contamination samples of near-saturation hydrocarbon and test the
connectivity of a high-mobility reservoir comprising unconsolidated laminated
sands where conventional probes perform poorly even at costly extended station
times
Solution: Deploy the 9-in Saturn 3D radial
probe with the industrys largest surface flow area of nearly 80
in2 for inducing and sustaining flow across a wide permeability
range while its reliable self-sealing technology provides circumferential
support in unconsolidated formations
Results:
- Successfully collected clean single-phase hydrocarbon
sampleswith only 1.2-wt% contamination measured by downhole fluid
analysis (DFA) and confirmed by laboratory analysis in only 2.5 h for
cleanup and sampling
- Quantified connectivity across the laminated sands
