"Korashina Anhdrite" formation in the Syrian Central Region's wells
considered as covering for "Korashina Dolimite" formation which is
a gas bearing reservoir, and consists of a succession of salt, clay,
and Shale. Much of the problems faced durin
g drilling this strata
like (High over pull/drag values, high pumps pressure, drill string
stuck), which led in some cases to stop the drilling operation, and
thus an increase in the drilling time, resulting in high final cost for
the completion of the well, salt saturated water based drilling mud
used to drill this formation but it did not completely solve the
problems.
This research aims to find out drilling mud treated with some kinds
of polymers and salts to be used to drill this formation with the
least problems.
