Process for diagnosing formation damage mechanism through the use of radially oriented core samples cut from the wellbore wall

摘要

This invention provides a method for diagnosing formation damage mechanisms through the use of radially oriented core samples cut from the wellbore wall. Core samples are taken from the wellbore and analyzed under a number of different analytical methods. From the analysis of the cores the operator should be able to determine the type, extent, and severity of the formation damage, as well as the distance that damage extends out into the formation.
