Abstract:
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 waterbearing 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 largediameter 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 in major savings in cost and time.
