... faults. The field has three subfields further divided into nine fault compartments ( Fig. 1 ). There are eight primary reservoirs with more than 20 sub-reservoirs stacked atop one another with multiple drive mechanisms, including water drive, gas-cap drive, and solution gas drive. Several of these sub...

..., these wells were deemed impossible to workover. The developed mud was utilized to successfully sidetrack a well and drill through the shales and underneath gas cap to target entry safely, proving this system can be used to re-enter these wells and tap into their production potential, saving the cost...

... Abstract Smart Auto Gas Lift (AGL) refers to a downhole system that utilizes gas from a gas zone or a gas cap in a well to lift oil below or above the gas zone in the same well. This paper illustrates a novel AGL intelligent completion design approach including candidate screening, pre-drill...

... Abstract The field in study has multiple stacked reservoirs with 10-20m oil column overlain by medium to large gas caps. PVT analysis from DST in the gas zones were available, which showed gas and condensate production at surface. Composition, PSAT and CCE data were available from surface...

... followed by rapid execution to get those early barrels. In Peninsular Malaysia BX is an oil rim reservoir with a large gas cap and moderate water drive. Oil production has declined rapidly in last few years with increasing GOR and water-cut. Existing models could not explain the current production...

... having low reservoir dip with a crestal moderate gas cap. With the intention to arrest gas cap expansion and also provide necessary pressure maintenance, water injection at the gas cap and also at the flank of the reservoir was initiated from the beginning of production ( Fig: 1 ). This is a channel...

... Abstract Effective exploitation of the thin oil rim in the Gunung Kembang field is particularly challenging because of the huge size of the overlaying gas cap, and the thickness of the oil rim varying between 25 to 40 feet gross pay interval, not to mention the sizeable water aquifer underlying...

... for water-flood development in March 2004. The Upper Jurassic Macedon reservoir comprise generally clean, high permeability, unconsolidated sandstone containing a 22° API, moderate viscosity, relatively low GOR oil which is overlain by a significant gas cap. The field has been developed to date via a total...

... Abstract The Enfield field has a 160 m oil column located between a medium sized gas cap and a water/leg aquifer system. Enfield is undergoing an active water-flood utilizing both up-dip and down-dip water injection. The water-flood reservoir management of such a field requires timely...

..., and the preparation of the well schedule (historical production, completions and operations). Abstract This paper explores the difficulties in modeling an oil rim with a large gas-cap using black-oil and compositional formulations. The example is from the Poleng field located in the Poleng Block, East Java...

Successful use of horizontal well technology requires an integrated team approach that incorporates all available data to justify a business case for drilling the well. The 37B sand in the Platong field has a 30-foot oil column, a small gas cap and a large...

... Abstract Exploitation of thin oil columns sandwiched between gas cap and water leg poses a unique challenge for reservoir development of many of such reservoirs worldwide, especially for those with high permeability and strong aquifer support. Issues important for reservoir management involve...

... Abstract Production practices for oil fields with gas caps usually centre around Conservation of the gas cap (energy) to maximise oil recovery. A less conventional but effective reservoir management approach involves an early gas cap blowdown phase in situations where the gas cap is small...

This paper targets the three most common horizontal well formations subject to completion: naturally fractured, matrix permeability dominated systems and formations bounded by a gas cap or an aquifer or both. The formation parameters that best...
