Methods And Systems For Testing Fluids On Crushed Formation Materials Under Conditions Of Stress

摘要

Methods and systems that may be employed to dynamically test the effect of fluids (e.g., well treatment chemicals such as well stimulation treatment chemicals, enhanced oil recovery “EOR” chemicals, etc.) on hydrocarbon recovery from crushed reservoir formation materials under conditions of applied stress. The disclosed methods and systems may be used in one embodiment to dynamically test types of low permeability formations (e.g., such as shale, limestone, quarried rock, etc.).

主权项

1. A method, comprising:
substantially saturating the pore spaces of a crushed formation sample with hydrocarbon; applying a compressional stress to the saturated crushed formation sample; flowing a test solution through the crushed formation sample while the crushed formation sample is subjected to the applied compressional stress to produce an effluent from the crushed formation sample; and determining the amount of hydrocarbon recovered from the effluent produced from the crushed formation sample while the crushed formation sample is subjected to the applied compressional stress.
