SUMMIT 8800 STREAM CONFIGURATION 06
6 .10 .3 Base sediment and water
Liquid Gas Steam
When crude oil is extracted from an oil reservoir or well, it contains certain impurities such as
water, and suspended solids. Sediment or mud is referred to the solid matter and water is the
result of the oil field itself, and from water injection used to extract the oil from the ground.
This section defines the selection process to arrive to an “in use” value for BS&W. There are
3 selections in order of priority with each 4 choices. The SUMMIT will start to check the first
selection. If the value is valid (not in alarm) then this selection will be chosen. If not, then the
second selection will be checked etc.
This following page sets the options and parameters for the calculations used for the base sedi-
ment and water correction in accordance with API Ch 12.2.1:
