Abstract
A heating probe and collection assembly is provided for evaluating free hydrocarbons and hydrocarbon potential of whole core. In one embodiment, the one or more assemblies are used with a core transport system to provide measures of hydrocarbon potential as a function of depth.
Claims18
Method for evaluating hydrocarbon potential of core taken from a wellbore comprising:
- contacting a portion of core surface of whole core taken from a wellbore with a heating probe comprising a high conductivity heating tip;
- controlling heat applied to the core by the heating probe in surface contact with the portion of surface of whole core to a temperature effective for causing release of hydrocarbons;
- causing at least a portion of released hydrocarbons to flow into a collection chamber;
- and
- collecting released hydrocarbons.

Apparatus for evaluating hydrocarbon potential of whole core taken from a wellbore comprising:
- a heating probe comprising a high conductivity heating tip for contacting and applying heat only to a portion of surface of whole core taken from a wellbore;
- a temperature controller for controlling heat applied to the core by the heating probe in surface contact with core to a temperature effective for causing release of hydrocarbons from core;
- collection means adjacent the portion of surface of whole core to which heat is applied for collecting released hydrocarbons;
- and
- a collection chamber adjacent the heating probe including a seal in sealing engagement with the core surface for causing at least a portion of released hydrocarbons to flow into the collection chamber.

Apparatus for evaluating hydrocarbon potential of whole core comprising:
- a heating probe and collection assembly for contacting, heating and collecting released gases from a portion of core surface of whole core taken from the wellbore, the assembly comprising a heating probe comprising a high conductivity heating tip for contacting and for applying heat only to a portion of surface of the whole core and a collection chamber adjacent the heating probe including a seal in sealing engagement with the core surface for causing at least a portion of released hydrocarbons to flow into the collection chamber;
- engaging means for causing the heating probe and collection assembly to engage the portion of core surface effective for releasing and collecting hydrocarbons from the portion of core surface and thereafter to disengage therefrom;
- and
- transport means for causing the core to be transported adjacent the heating probe and collection assembly for being engaged at intervals along the core by said assembly.
