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 />
