Method to assess the placement of Cement and Gravel Packing Wells by means of raw materials that have low levels of radioactivity

摘要

Abstract methods are described for recording a well using natural Radioactivity originates Particulate Clay based.The Methods may include the use of a Slurry of Gravel Pack containing a liquid and particles of Gravel Pack copy hydraulically for particles in an area of retaA PERFORATION and Gravel underground through a training Data Set and obtain a Post Gravel Packing down in the drilling through a Subterranean formation detectedR to detect gamma rays and gamma rays are a native of Radioactive particles from the Gravel Pack.The Methods may also include the use of the Data Set after Gravel Packing to determine a location of the particles of Gravel Packing and correlate The location of theParticles of Gravel Pack to a measurement of depth of drilling to determine the locationHeight and / or percent of filler particles of Gravel Packing placed in the area of PERFORATION Gravel Pack.
