e)
Average specific gravity of the crude at 60oF / density of product at 59oF.
f)
Equivalent API Gravity / SG of the cargo.
g)
Volume correction factors.
h)
Gross and net quantities of the cargo in barrels, long tons, cubic meters and metric
tons as obtained from the tank dips/Meter Readings.
i)
Absolute values of BS&W in barrels and long tons.
j)
Meter Factor

5.2.3.2 The Average BS&W for the whole cargo in a case where loading has taken place from
more than one tank shall be obtained by dividing the total BS&W value by total gross
volume at 60ᵒF of the cargo and expressed in percentage.
5.2.3.3 The Equivalent API Gravity of the cargo in a case where loading has taken place from
more than one tank shall be obtained as follows:
5.2.3.3.1 Calculate the long tons per barrel factor of the cargo by dividing the net weight in
long tons by its net volume in barrels.
5.2.3.3.2 The factor thus obtained is referred to table 29 of the ASTM table of standards to
obtain the corresponding dry specific gravity, which is in turn referred to table 21 of
the ASTM tables to determine the equivalent API gravity of the cargo.
5.2.3.4 In case of auto-sampler failure, pre-export BS&W shall be used for determining the
quality of petroleum and petroleum product exported.
5.2.3.5 After all the necessary values are determined and entries have been made in the
relevant document, it is distributed in the following manner:

Original Copy - To the consignor or his authorized representative.
Duplicate Copy - To the Department of Petroleum Resources Divisional office in the area.
Triplicate Copy - To the facility operator.
Quadruplicate Copy - To be retained among the records of the Department of Petroleum
Resources facility office.

5.3 Export Permits
Requirements for granting Crude Oil/Condensate/GTL/Gas Export Permits is as follows:
5.3.1 New Application
Companies making a foremost application for export permits must have a concession (Oil
field) or a partnership in the concession with a consent letter from DPR conveying the
approval of the Honourable Minister for the ownership of such. In addition, a consent letter
from DPR conveying the assignment of interest to participating company(s) shall be
included for first application.
