Our Innovations
Using our in-house customised innovative technology, the Live
Intervention Platform for Dual Head Wells with Beam Pumps, and
following a successful trial done on Qaharir 32 last year, we are
currently providing a real production logging (PLT) for PDO on
Thuleilat-83. In PDO’s history (and presumably the rest of the
world’s), this is the first time logging has been performed safely while
producing from a beam (sucker rod) pump. The advantages of PLT as far
as reservoir management and production injection optimisation go are
countless especially in the light of rising oil prices. It is impressive to see that
following the trial success, PDO continued installing dual-head
wellheads.
Key Projects of New Technology and Production Solutions (NTPS)
The New Technology and Production Solutions (NTPS) department is a new
technologies pioneer and customised production solutions inventor.
Five innovative technologies second to none are being developed this
year.
1. Live Well Intervention Platform
Dual completions provide beam pumps with a step change in surveillance
and effective reservoir management. The platform, which is indigenously designed,
developed and fabricated by NTPS, allows CTU / Wireline entries through
tubing in dual completions, while the well is produced through other
tubing. Many activities are made possible without WPH intervention
such as production logging, stimulation, C/O fills, pressure surveys,
through tubing perforations and through tubing water shut off.
Platform allows better understanding of flow distribution, lower risk
of water shut off / stimulation and improved and accelerated recovery
by targeting re-completion.
Currently the Live Intervention Platform is on contract in PDO operations.
2. Downhole Tool for Curing Lost Circulation
Partial / full lost circulation is a common problem in oil field
drilling / work over operations. One common method to cure lost
circulation is to make 2 components gel upon contact. This method is
generally not successful because components fail to see each other or
see each other in a suboptimal place in the lost circulation zone.
The indigenously developed and patented downhole tool allows 2
components to see each other in the lost circulation zone and gel up.
If required, cement can be pumped through inner / outer string to enhance
chances of stopping the losses.
Depending upon severity and nature of losses, chemical fluid systems
can be selected.
Currently the Downhole tool is being field tested as a part of PDO New
Technology trials.
3. Radial Jet Enhancement Technology
This is a patented technology and NTPS has tied-up with Well
Enhancement Services to bring the technology to Oman. Hydraulic power
is used in conjunction with jetting hose and deflecting shoe to make
one inch diameter 300 feet long holes in different directions and at
different depth. The process is fast, economical and can make old
wells economically viable.
The technology is planned to be field
tested in Oman in QIII, 2006.
4. Intelligent Self Optimising Gas Lift Package
This package allows production maximisation without human
intervention. Changes in reservoir conditions are drivers; hence gas
lift performance is always within best efficient point in the design
curve. The resultant effects are no gas wastage, real time data
availability in the office, total guidance to operator, minimal
manpower and prioritising nearby wells to be closed if shortage of gas
prevails.
This technology will be field tested in QIII, 2006.
5. Intelligent Self Optimising Beam Pump
This package is very similar to gas lift package. The only difference
is that variable speed of the beam pump motor is fed into the
performance optimisation loop.
This technology will be field tested at the end of 2006.
