- gas and filtrate. Indicates a gas zone. If log interp and other data is indicating the section is wet then perhaps you have a pocket of gas within a largely water wet zone.
- gas and formation water. This usually indicates youve either 1) sampled right on a gas water contact (not the case here) or 2) youve sampled a zone thats water wet with residual gas present.
- gas and formation water and filtrate. Same scenario as gas and formation water. Filtrate contamination due to fluid didnt properly cleaning up prior to taking sample
