The oil and gas industry had a commitment
to screen all its cuttings piles for environmental significance prior to June
2008 against the assessment criteria specified in OSPAR recommendation 2006/5. Aquatera
was contracted by BP to undertake this exercise on their behalf.
A range of geophysical and environmental data supplied
by BP was used in conjunction with a number of factors generated in-house using
existing R&D data to estimate the two key assessment parameters defined by
OSPAR – oil loss to water column and persistence. The report provided an
assessment of all of the relevant multi-well installations and identified the
potentially significant data gaps.
