The influence of heterogeneity of lacustrine shale facies on rock mechanical properties and brittleness: a case study of Jurassic lacustrine shale reservoirs in Northeast Sichuan Basin

IntroductionDue to the significant increase in plasticity under conditions of high temperature and pressure, the existing single brittleness evaluation methods prove inadequate for accurately characterizing the compressibility of deep shale in northeastern Sichuan, thereby severely limiting the opti...
