..., vertical producers for commingle production with other layers is common with a percentage of 70.4%. The perforation is located at the top of the reservoir usually. For these wells, watercut rises sharply without water-free production. The average limit of watercut is about 64%. The calculated watercut...

... (condensate 60.9° API) travels up the tubing, and injects into oil zones, soaks for 2-3 weeks to allow the gas to migrate up-dip from the well and to displace up-structure oil downward towards the producer, then goes back on production. After gas/condensate zones deplete, high-GOR light zones...

...Spatial and temporal resolutions Abstract For several years, there has been an interest in responsive "NanoProbes," which, when injected along with waterflooding could sense reservoir properties locally along the trajectories they follow from injector to producer wells, giving a low-cost...

Voidage replacement ratio (VRR), which is defined as the ratio between the volume of injected fluid and the volume of produced fluid, measures the rate of change in reservoir...

The main result is the Fluid Path Conceptual Model (FPCM) where aquifer and injected water movements...

... From 2010, 8 producers cut water and were shut-in due to sand production and productivity reduction associated with water breakthrough. Decrease of production, triggered second round of drilling campaign, started in 2012. Since 2012, 11 sidetracks and 4 new wells were drilled (among them 11...

... Abstract An Ecuadorian lease ("Bloque 61") composed of 14 oil fields represents the most productive asset in the country. It contains 5.3 billion barrels of original oil in place (OOIP) distributed in four complex producing reservoirs. After 44 years of production and with a decline rate of 31...

The heat power of the heaters with time was also optimized which required the highest power of 2500W/m for each heater. Following which...

Of course, each input parameter has an associated membership function in our fuzzy logic system. Several...
