A preliminary water injection study using a dynamic simulation model was completed in 2011 for the Lam 75 area and an injectivity test
was conducted in June 2011.
At Saponis an injectivity test
was conducted on the Ordovician open perforations in the Lebork S-1 well.
The Paralana 2 well's casing was perforated over the depth interval of 3,679-3,685 metres in early January 2011, and an injectivity test
was successfully undertaken.
It is anticipated that the injectivity test
and possibly the static kill will take place Tuesday," BP said in a brief statement on Monday.
This multidisciplinary field has become a leading technology for modeling and solving real-life combinatorial problems in fields as diverse as production planning and scheduling, product configuration, molecular biology, medical diagnosis, and robotics, and these 27 papers reflect that diversity, covering the past, present and future of constraint programming, constraint modeling and reformulation, including graphing, symmetry in constraint satisfaction problems, interval analysis in constraint propagation and applications, including an interval analysis that produces a guaranteed numerical injectivity test
, local search techniques in constraint satisfaction, preferences and soft constraint and constraint programming for graphical applications.
After extended delays due to weather, crew and equipment associated with the injectivity test
were mobilised to Paralana-2 (Beach 21%) in late December.
In additional, an injectivity test
and long term leakoff test will be performed to confirm injection rates and pressures.
Operations to perform an injectivity test
on the Paralana-2 geothermal well commenced over the last week.
An ACTive Profiling distributed temperature survey was then used to record an injectivity test
to provide data for water-injection planning.
In a rig-less operation, coiled-tubing was run to acidize the injection zone of the 28,257-ft well with a VDA* Viscoelastic Diverting Acid treatment, before a memory production logging tool was used to record an injectivity test
for water-injection planning purposes.
The report discloses the results of laboratory investigations, a field injectivity test
, and computer simulation work in which CO(2)-flooding was found to be capable of significantly increasing the recovery of oil from the reservoir.
A further injectivity test
did confirm the permeability of the formation sands.
