1.4 Core analysis <strong>and</strong> data interpretation<br />
Challenge commentary<br />
Routine core analysis <strong>and</strong> special core analysis<br />
(SCAL) are key to improving our underst<strong>and</strong>ing<br />
of oil <strong>and</strong> gas reservoirs <strong>and</strong> gaining a true<br />
estimate of their reserves. The data from these<br />
various analyses drives field development<br />
decisions <strong>and</strong> drilling campaigns.<br />
Unfortunately, local Kazakhstan capability in<br />
this area is limited <strong>and</strong> most of the work has to<br />
be done overseas, which leads to higher costs,<br />
inconvenience, <strong>and</strong> delays.<br />
Moreover, full or partial cores cannot be<br />
exported from Kazakhstan; only limited<br />
plugs from the core are allowed out of the<br />
country <strong>and</strong> this takes a long time to arrange.<br />
This erodes the value of the core, creates<br />
uncertainties with analysis results <strong>and</strong> severely<br />
holds up development decisions.<br />
There is also an inability in Kazakhstan to<br />
conduct core displacement tests with live sour<br />
fluids. These tests are hazardous <strong>and</strong> can only<br />
be done in Edmonton, Canada. Considering<br />
how many large sour fields there are in<br />
Kazakhstan, it would make huge sense to bring<br />
this <strong>technology</strong> into the country. It would raise<br />
underst<strong>and</strong>ing of relative permeability <strong>and</strong><br />
help determine remaining oil saturations, thus<br />
accelerating the development of sour fields.<br />
The challenge is to establish core analysis<br />
laboratories in country capable of providing<br />
services that match those available<br />
internationally. The staff for these core analysis<br />
laboratories will need to suitably trained;<br />
particularly important will be the development<br />
of expertise in analysing carbonate reservoir<br />
cores <strong>and</strong> carrying out studies, for example,<br />
designed to mimic the acid treatment of these<br />
cores at abnormally high temperatures <strong>and</strong><br />
pressures.<br />
