... challenging if conventional development strategies are applied. Due to the high reservoir tightness, permeability contrast among different flow units and dual permeability effect (matrix and natural fractures), well productivity potential significantly depends on the effectiveness of subsequent stimulation...

... The hydraulic aperture (e) of a given fracture is the aperture of an ideal fracture assimilated to two parallel plates that would have the equivalent permeability. By assuming that Poiseuille’s law applies and considering a compressible perfect gas in isothermal conditions, the hydraulic aperture...

... challenges in general and specifically to overall loss in downhole injectivity. With a naturally fractured carbonate reservoir it makes the conventional remedial activity such as (Coil Tubing Unit) CTU or bullheading acid matrix stimulation is expensive and increases the risk of connecting existing fractures...

... Abstract The hydraulic fracture modeling is critical for the well dynamic performance and development optimization in the fractured condensate reservoir. The conventional approach based on LGR (Local Grid Refinement) is widely used but with low computational efficiency, and sometimes...

... The main reservoirs identified were the Middle Marrat dolomites (primary objective) and the Najmah Limestone together with a potential unconventional resource, an Organic Carbonaceous Shale in Najmah (OCS). The reservoirs are characterized by extensive natural fractures, which are currently being...

... It is assumed that the bedding layer slippage caused by shearing at the contact interface between the hydraulic fracture and the bedding layer has propagated and reached the maximum distance away from the fracture ( Li and Wu, 2022a ). Eq. 3 shows the calculation of the straightened stress...

... In typical fractured reservoir GOGD development, hydrocarbon gas is injected into the fractures. The density difference between the hydrocarbon gas and the oil cause the oil to drain to the bottom of the reservoir where it can be produced. Abstract The North Oman "A" Field is a giant...

... of the reservoir setting and difficulties in locating the natural fractures. Success in developing such tight carbonates depends on the integration of high quality seismic, borehole imagery, petrophysics, and dynamic data. The approach allows the right access to natural fractures by the wellbore and to release...

The article also sets forth a flow chart to exemplify the optimum path to manage and sustain retrograde gas condensate reservoirs successfully. condensate reservoir wellbore borehole layered reservoir complex reservoir reservoir surveillance fracture...

... Abstract Field X is one of the largest oilfields in Sultanate of Oman and has highly fracture carbonate reservoirs. The field has been under production since 1967 and has undergone multiple phases of production including: pressure depletion, simultaneous gas and water injection within different...

... Abstract We discuss the application of overflushing along with pillar fracturing in a mature oilfield in Ecuador, where an effective high conductivity (high proppant concentration) fracture is required to enhance productivity because of low reservoir pressure and high permeability. Hydraulic...

... Abstract Multi-stage hydraulic fracturing has recently gained strong interest in unconventional plays in the Middle East due to high natural gas production potential. However, prevalent characteristics of the area, including high-pressure / high-temperature (HPHT) conditions and presence...

... Abstract The existence of faults, pre-existing hydraulic fractures, and depleted areas can have negative impacts on the development of unconventional reservoirs using multi-fractured horizontal wells (MFHWs). For example, the triggering of fault slippage through hydraulic fracturing can create...

... Abstract Casing deformation has been detected in Oman's deep gas wells after hydraulic fracturing, particularly in Saih Rawl (SR) and Burhaan (BRNW) fields across Miqrat and Barik units. Hydraulic fracturing is a key enabler for the development of these reservoirs, understanding the conditions...

... Instances of horizontal development wells in Reservoir 2 crossing sub-seismic faults are rare, and when they do occur, fault throws are estimated to be <10ft. Tectonic fractures have been interpreted from LWD WBI, however these are rare, with extremely low density per 100ft drilled. Drilling...
