... strength are critical pieces of information needed to decipher the tensile or compressive rock strength and variation in the horizontal stress distribution. Studied wells in the KG basin consist of sediments ranging from Upper Cretaceous to lower Jurassic predominantly. Pore pressure is calculated using...

... ABSTRACT: The Panna Formation is the oldest hydrocarbon-bearing tertiary sedimentary unit in the Western Offshore Basin (WOB). Drilling in Panna is plagued by sudden pore pressure ramp resulting in the mud gain and mud-loss situation. A comprehensive study is carried out across 5 blocks of WOB...

... material tends to flow in the direction in which the pore pressure and flow resistance are lowest. The results of this research show how crucial the correct selection of the grouting parameters is for the success of a grouting activity. 1. Introduction Besides the conventional method of rock protection...

... of critical pore pressure change to trigger seismicity ( pc/h), referred to as the fracture criticality, has been proposed to represent the critical state of subsurface fractures. The fracture criticality is subjected to variability due to heterogeneous fracture attributes and rock properties. The statistics...
