CHALLENGE
Perform simultaneous three-phase well
tests at a remote, unmanned platform
while ensuring reliable results.
SOLUTION
Use the PhaseTester* portable multiphase
well testing equipment to perform a multiple
choke study and obtain real-time three-
phase test results without separation.
RESULTS
Successfully tested five wells in 16 hours
while remotely monitoring production in
real time.
“The mobile PhaseTester meter was
the perfect solution to our production
challenges, which included well
testing at our remote platform with
minimum facility, limited space, anda lack of power supply; collecting
single-phase samples in the absence
of test separators; and back allocation
production for reservoir engineering
and management purposes.”

Deputy General Manager, Production
ONGC
Remote offshore well requires real- time multiphase testingONGC constructed an unmanned, remote
platform in the Bassein & Satellite field located
offshore Mumbai. At the time of development,
the platform was constructed with minimum
facility and a projected life of about 5 years.
All of ONGC’s wells in the field were initially
tested in 2002, and those test results had beenused as a reference ever since. When gas
demand increased, ONGC wanted to increase
the choke size and plan an efficient workover
program for the wells. However, because each
well’s production data at that time was not reli-
able, reservoir engineering and management
decisions were difficult to make with certainty.
Mobile multiphase meter quantifiesreal-time data without separationAfter consulting with Schlumberger, ONGC
chose to test the wells using PhaseTester
equipment with Vx* multiphase well testing technology and perform simultaneous testing
operations while the rig was drilling a nonpay
zone at an adjacent well.
Meter successfully, accurately testswells in 16 hoursTwenty hours after the equipment arrived
at the offshore platform, the well services
team was ready to begin testing. InterACT*
connectivity, collaboration, and information
system was used to monitor the test from the office, enabling the ONGC team to make
real-time decisions. All 5 offshore wells were
comprehensively tested in 16 hours.
