Calculation Examples

BSW Example

Assume a fluid flow rate of 20 bbl/day, a 10% BSW, and a 0% shrinkage. he oil and water !rodu"tion is "al"ulated as follows#

BSW and Shrinkage Example

Assume a fluid flow rate of 20 bbl/day. Shrinkage is $% and BSW is %. What are the oil andwater rates&



Condensate Example

Assume a '( "ondensate rate of 20 bbl/day and shrinkage of %. he )( *ondensate +ate is

"al"ulated as follows#

CGR Example



he test rates for a !arti"ular time of the test are as follows#

• as -eter 1 1.2 mms"f/day

• as -eter 2 1. mms"f/day

• *ondensate -eter 1 3 bbl/day

All three meters are 4n"luded in the otals.

*+ otal *ondensate +ate / otal as +ate

3 bbl/day / 51.2 6 1.7 mms"f/day

1.1 bbl / mms"f

Water Cut Example

Assume a well is !rodu"ing 10 bbl/day of fluid with a BSW of %. he well is also !rodu"ing 2

bbl/day of water from the water leg of the se!arator. What is the water "ut&

BSW Water 10 8 0.0 0. bbl/day

otal Water 2 6 0. 2. bbl/day

otal 9il 10 8 51 : 0.07 . bbl / day

Water *ut 2. / 52. 6 .7 8 100% 20.%

GOR Example

he test rates for a !arti"ular !oint in time during the test are as follows#

• as -eter 1 1. --s"f/day

• as -eter 2 0.; --s"f/day

• 9il -eter 1 0 bbl/day


9+ otal as +ate / otal 9il +ate

WGR Example

he test rates for a !arti"ular time of the test are as follows#

• as -eter 1 $. --s"f/day

• as -eter 2 1.; --s"f/day

• Water -eter 1 13 bbl/day


he o!erator "hose to e<"lude Water -eter 2, therefore only three meters are in"luded in thetotals. 5Water -eter 2 was not in"luded, so its rate is not !art of the W+ "al"ulation7.

WOR Example

he test rates for a !arti"ular !oint in time during the test are as follows#


• 9il -eter 1 0 bbl/day

Interpolation is defined as:

he assignment of =alues to !oints intermediate to two data !oints. 4nter!olation is used to fill inmissing data in well logs and other data sets

>alues are inter!olated for time entries without "orres!onding meter readings. his feature "an

inter!olated =alues is in the following !i"ture#
