CHAT - Cased hole Analysis Tool:
Cased Hole Analysis Tool Is a measurement system that provides accurate data about reservoir rock
parameters, identifies reservoir fluid types, and is used extensively to identify and describe many well bore conditions that can
result in production problems. The core measurements of this logging system include thermal neutron, epithermal neutron, and behind
casing formation density. Various production logging tool modules can be combined with the 'Cased Hole Analysis Tool'. This makes
it possible to configure effective measurement combinations for a wide range of well conditions and logging objectives..
Modular tool design results in the most effective and cost efficient tool configuration for each
The neutron and density components of the 'Cased Hole Analysis Tool' are based
upon the same physics as conventional open hole logging tools. This provides the sensitivity required for accurate time-lapse comparisons
to identify subtle changes in reservoir conditions.
All conventional industry data formats are supported
All components of the 'Cased Hole Analysis Tool' are military grade resulting in reliable operation within the ratedspecifications
of the equipment.
Timely turn around for all analysis products is guaranteed regardless of how remote the well site location.

-oil/water contact @ 1121
Initial production started from squeezed perf interval / high GOR resulted worn
gas being coned down through the oil / stair step neutron porosity (1113.5-1117) caused by residual gas left in near wellbore region
after perf interval squeezed off.
