... is turned off. It occurs in ROP, when the controller is in ROP mode and does not switch to WOB during the stand. Step changes in the ROP and RPM signals due to set point changes were ignored as this is not a system instability. The WOB signal will vary at a constant ROP due to variation in formation...

... plus CO 2 , as shown in Figs (6 & 7 ). It appears that the isotopes of the gas compounds from the seven samples are quite close and display very small variations. The isotope variations from the studied gas samples are too small to suggest any impact from adsorption-desorption. This could result...

... Permeability is a physical property that is affected by the variation of the net effective stress, pore body, and throat radius ( Boualam et al., 2020 ) where net confining stress is defined by ( Jones 1988 ) as the difference between hydrostatic confining stress and the pore pressure. This method...
