INVASION PROFILER™ is a tracer service that is utilized in
either water or oil-based drilling fluids to measure filtrate invasion in coring
and drilling operations.
INVASION PROFILER™ features two types of tracers:
One or both can be introduced into the mud system prior to drilling a core or drilling
through a zone that is planned for formation fluid sampling.
What makes INVASION PROFILER™ effective is that neither tracer
occurs naturally; when either tracer is found in a core or formation fluid sample,
it is due to drilling fluid filtrate invasion. The ability to trace both phases
of an oil-base drilling fluid also exists by utilizing each tracer simultaneously.
There are no temperature limits on INVASION PROFILER™ tracers
and mud properties are not altered.
INVASION PROFILER™ increases accuracy and confidence in the
determination of fluid saturations from core analysis and fluid properties from
formation test samples which are vital for refining the reservoir and petrophysical
models essential in reserve estimation and facility design.
INVASION PROFILER™ is extremely effective in determining:
