TEST PROCEDURE - WATER TEST
OBJECTIVE:TO COLLECT A REPRESENTATIVE FORMATION WATER SAMPLE FROM THE WATERBEARING SAND.
THE DST STRING WAS RUN USING GEOVANN GUNS, BAKER PACKER, HALLIBURTONrfEIGHT SET PACKER, TEST TOOLS AND PRESSURE GAUGES, FLOPETROL EZ TREE,FLOWHEAD AND SURFACE EQUIPMENT.
AFTER PRESSURE TESTING EQUIPMENT A BLIND BOX WAS RUN TO TAG DIESELCUSHION. SEVERAL ATTEMPTS WERE MADE BEFORE THE HALLIBURTON LPRN VALVEWAS OPENED. THE GEOVANN FIRING BAR WAS RUN ON WIRELINE. AFTERSEVERAL ATTEMPTS THE GUNS WOULD NOT FIRE. RIGGED UP TO BAIL SCALEWHICH WAS LYING ON TOP OF GUN. 26 BAILING RUNS WERE MADE THEN THEGUNS WERE FIRED.
AT 09:43 ON 16/5/83 THE WELL WAS OPEN FLOWING ON FULL CHOKE TO GAUGETANK 181/64.
AT 11:15 THE WELL STOPPED FLOWING.
AT 12:06 THE CHOKE MANIFOLD WAS CLOSED.
AT 12:13 THEAPR-MWAS OPENED.
AT 12:14 OPENED CHOKE AND STARTED TO REVERSE OUT FLOWING TO GAUGETANK. DURING THE REVERSING PERIOD 24 WATER SAMPLES WERE COLLECTED ANDSOME SAND SAMPLES.
AT 13:16 REVERSING WAS COMPLETE. PREPARE TO ABANDON TEST.
WATER TEST COMPLETE.

-LIQUID PRODUCTION RATE MEASUREMENT -
2.1 - MEASUREMENT WITH TANK -
Vo = V x K 5 ( 1 - BSW )
Vo : Net oil volume at 60°F and atmospheric pressure.V : Gross oil volume measured by tank gauging.K : Volume correction factor to be applied between the
tank temperature during gauging and 60° F.BSW : Basic sediments and water.
2.2 - MEASUREMENT WITH METER -
a) Shrinkage tactor is measured by shrinkage tester.
Vo = Vsxfx(1-Shr )xKx(1-BSW)
Vo : Net oil volume at 60° F and atmospheric pressure.Vs : Cross oil volume measured by meter under separator conditions.
f : Meter correction factor = Volume measured in tankVolume measured by meter
Shr : Percentage of oil volume reduction between separator and tank• conditions, reported to oil volume at separator conditions.
K : Volume correction factor to be applied between the finaletemperature during shrinkage measurement and 60° F.
BSW : Basic sediments and water.
b) Shrinkage factor is measured with tank.
Vo = Vs x (1 - Shr') x K x (1 - BSW)
Vo, Vs, K and BSW : Same meaning as in a).(1 Shr') : Shrinkage factor including meter correction factor.
