Sampling Considerations: • Gas, Liquid and Rock samples collected for offsite analysis must be carefully preserved and archived so that they may later be accurately correlated with depth. • It is desirable to dictate from which depths samples will be derived. • It is imperative to know from which depths the samples were derived.
IsotechIsotubeAutoloader Isotubes contain radio tags encoded with unique serial numbers The Autoloader adds a time stamp to each tag together with its own serial number each time a sample is taken Reduces analysis of empty tubes Precludes “rapid-fire” “catch-up” sampling to compensate for missed intervals
Sampling Limitations: • The Autoloader encodes each isotube with its own serial # and a time stamp • This information, together with the drilling record is sufficient to accurately and unequivocally determine sample depth • The Autoloader can be set to sample on regular time-based intervals but as it does not monitor depth or chemistry, it can’t be programmed to trigger samples based on either of these criteria
Mass Spec Chemical Profiling with the Dq1000TM The Dq1000 is a portable quadrapole mass analyzer for use on drilling wells. It replaces all conventional gas detectors. It analyzes C1-C10 petroleum species, and inorganic compounds such as CO2, He, N2, O2 and sulfur bearing volatiles. It can discriminate among paraffins, naphthenes and aromatics, as well as contributions from the drilling fluid. The Dq1000 is capable of delineating charged zones, petroleum type, compartmentalization, fluid contacts and seals to a much greater extent than conventional instrumentation. Interpretation of data follows from our 18 years of experience with subsurface fluid chemistry
FIT-Dq1000 Chemical ProfilerIsotech-Isotube Autoloader Interface • By interfacing the Isotube Autoloader with the Dq1000 Chemical Profiler, Isotube sampling can be driven by both time and depth-based criteria • Sampling can also be triggered remotely – while viewing gas composition data off site using the Dq1000 monitor software • Eventually, auto-triggering based on chemical criteria will also be possible
