Pulsating Separator Technology Helps North Sea Operator Reduce Oil on Cuttings by up to 26%
Cuttings samples show the SCREEN PULSE fluid and cuttings separator reduced OOC in the 8.5-in and 12.25-in sections by up to 26% over a 13-day period. By optimizing separation efficiency, the operator reduced OOC by an average of 17.9% compared with when the separator was not in use, helping the operator save on average USD 2,797/d in drilling fluid costs while drilling the two sections.
A North Sea operator needed to minimize
waste, costs, and HSE risk while drilling
multiple well sections with OBM.
M-I SWACO, a Schlumberger company,
recommended installing the SCREEN PULSE fluid and cuttings separator to improve
the fluid recovery of the operator’s existing
VSM-300 shakers. The innovative separator
stripped the cuttings of free fluid, reducing
oil on cuttings (OOC) by up to 26% compared
with the shakers alone.
