... correspond to production-injection performance. New infill wells show massive bypass oil which is not expected at 7+ years steam flooded area. It also enables steam injection optimization by improving pressure depletion and lateral connectivity. It impacts faster heat maturity and furthermore will enable...

.... The field is mainly divided into three areas called the East, West, and Central Areas. The field has been producing primarily under a natural depletion drive supplemented by water and gas injection as an IOR strategy. Several development campaigns have been carried out in the past where additional infill...

... Abstract Field A is producing from natural depletion drive oil reservoirs with large gas cap. The field was under production curtailment, governed by gas-oil-ratio (GOR) limit to preserve the reservoir gas cap size. As the field continues to produce, the oil rate has declined while GOR...

... production data from the early production wells were used to improve the 2010 sanding model. The updated model also showed low risk of sanding for planned horizontal wells and suggested no sand control would be required even at high depletions. The last model update in 2019 was improve by using...

... are reduced to a more manageable 20 models for simulation using a distance-based K-medoid algorithm. Maps of maximum depletion and inflation are generated for each of the medoids. With this work, the importance of probabilistically assessing reservoir pressures is demonstrated in the context of developing...

The study presents a 3D finite-element-based fully coupled flow and geomechanics model that simulates the poroelastic behaviors of pressure...

... and development wells drilled in the field did not experience any wellbore stability issues. During drilling of the X-8, wellbore stability and collapse caused significant problems and resulted in the sidetracking of the well three times. Prior to the drilling, it was recognized that depleted reservoir conditions...

... Abstract Imbibition only relative permeability is commonly used to model water influx in water-drive gas reservoirs, however an aquifer is rarely strong enough to maintain constant pressure support. Continued pressure depletion in the part of the reservoir swept with watercauses expansion...
