Oil & Gas
2nd International Conference and Expo on
In oil wells where viscosity of the crude is very high (heavy
oil), steam is injected to increase the fluidity and mobility
of the oil. This steam injection requires large quantities of
water, generally transported from nearby fields. In some
oilfields in the Gulf region, and around the world, the water-
bearing sandstone is highly fragmented. Sand screens made
of carbon-steel do not provide reliable sand control, as they
quickly undergo quite serious corrosion. Some oilfields
have started to try out non-metallic materials (such as
strengthened polymers) because of their non-corroding
nature. Based on a hit-and-trial approach, around 15% wells
have reported failure due to screen collapse. In collaboration
with a regional petroleum development company, an
experimental testing facility was designed and developed at
Sultan Qaboos University for integrity assessment of large-
diameter hard polymeric pipes. This included design and
construction of the test setup and jigs and fixtures, together
with a compatible testing scheme. Following procedures
set forth by international standards, polymer pipes had to
go through a 2-3-month ageing process before mechanical
testing, in brine solution matching the salinity of the water
field. For testing under compressive loads, a fixture was
developed for the pipes to be tested on a heavy-duty
universal testing machine, using several sets of strain gages
to record dynamic behavior in axial and hoop directions.
A full-scale test facility was designed and constructed to
determine collapse strengths of polymer pipes of around
6-m length, using steel pipes of 16-in diameter as outer
casings. Apart from the scientific contribution, findings from
this work can serve as prequalification of polymer pipes for
appropriate fields, and result inmajor savings in cost and time.
