Abstract
A new coring tool which samples core and its fluid contained within pores has been designed,<br>developed and tested in field trials.<br>The tool is run as a conventional operation, with minimal modifications to routine coring operations.<br>The Liquid Trapper™ consists of a specifically designed liner assembly, which through an inflatable seal<br>system ‘traps’ the liquids escaping from the core during the retrieval of the corebarrel to the surface.<br>Cores and fluids obtained allow the determination of the fluid saturations representative of formation saturations.<br>The technique of Liquid Trapper™ coring was originally devised to provide in-situ residual oil<br>saturations, however, because crude-oil samples are collected, the Liquid Trapper™ also furnishes<br>additional data and information that is essential for formation evaluation.<br>The tool has been proven in a number of coring operations for a variety of rock types.<br>This paper describes the features and operation of the Liquid Trapper™ tool and a case history is<br>discussed to illustrate its potential use in formation evaluation.
