pressure n: pressure at the bottom of the wellbore during normal oil production.
the distance outward from the wellbore to the leading edge of the lost fluids. Varies with the permeability of the zone.
n: the unwanted migration of the liquid part of the drilling mud or cement slurry into a formation, often minimised or prevented by the blending of additives with the mud or cement.
n: the transfer of the liquid part of the mud to the pores of the formation,loss of fluid (water plus soluble chemicals) from the mud to the formation can only occur when the permeability is sufficiently high,if the pores are large enough,the first effect is
the rate of loss of liquids to the formations from the fluid being circulated through the wellbore.
