These samples come from drilling mud and cuttings and provide baseline data needed to characterize the well as production begins and comingles all of the microbial DNA.
By sampling the drill cuttings and using a microcomputer at the well site, the rock drillability can be determined by the energy law measure system.
能量法岩石可钻性测定系统是通过采集钻井井口岩屑并利用微机来测定岩石的可钻性。

Because the formation fluid can not seep in well bore, people find out reservoir usually by cuttings logging, gasometry logging, core analysis, fluorescence etc.
