..., to further clarify the exploration potential of such shale oil reservoirs, operators have deployed many wells and adopted massive fracturing treatment with large Stimulated Reservoir Volume (SRV) strategy, but the post-fracturing production is unstable and unsatisfying. The large amount of water consumption...

... Abstract During shale gas well fracturing, the equilibrium of fracture propagation is poor due to the influence of formation heterogeneity and stress interference between fractures. Wellbore temporary plugging is an effective measure to control fracture propagation. However, in temporary...

... Abstract Distributing the injected proppant equally between different perforated clusters remains challenging and requires optimization to achieve effective stimulation treatments. The distribution of proppant is essential to sustain the induced fracture conductivity and maximize...

... Abstract Fault-controlled fracture-cavity reservoirs are significantly influenced by strong fault activity and dissolution processes. Injected water tends to advance rapidly along fault zones, resulting in a limited waterflood sweep area and ineffective displacement, highlighting the urgent...

... Abstract Objectives / Scope The Abu Ghirab oilfield is located in the Missan province, southeast Iraq, near the borders with Iran. The Asmari Group A reservoir mainly consists of Tertiary carbonate formations with low to medium interconnected porosity; natural fractures and vugular storage...

... to understand the initial injectivity index and establish baseline for the zone of interest as well as the adjacent zones directly above and below it. After that, conduct a minifrac to measure key properties such as the treatment fluid leak-off and the fracturing pressure to calibrate the geomechanical model...

... Abstract The reduction in well spacing for multi-fractured horizontal wells in shale gas reservoirs increases the risk of fracture communication. Fracture hits and induced fracture communication between parent and child wells can significantly reduce the gas production of the parent well...

.... AI-driven key deliverables included fracture/fault characterization, quantifying diagenetic porosities and extraction of rock permeability indices. AI-driven analysis saves time (and cost) while sustaining quality. What usually takes days or even weeks is now accomplishable in hour or even minutes...

... characterize the fractured reservoir and revealed the impact of the fractures and secondary pores on the producibility. The igneous rock reservoir is deep buried with the depth of more than 4000 meters, porosity less than 5% and permeability less than 0.1mD, which makes the reservoir more complex compared...

... criteria and the results of 1-D geomechanical model. We predict overpressure and simulate in-situ stress for multi-formation systems using different models tailored to the overpressure formation mechanisms of various lithologies, and quantitatively predict pore pressure, breakout pressure, fracture...

The objective of this study was to evaluate the permeability variations and fractures in a horizontal evaluation well by calibrating the permeability calculation...

... Abstract A persistent challenge in leveraging data analytics in hydraulic fracturing operations is the prevalence of unstructured data formats and the lack of some data on rock mechanics and reservoir parameters. In this paper, an in-house code was developed to majorly 1) automate data...

... a substantial financial burden to the operation. Similarly, downhole losses—when drilling fluids are lost into the formation—pose a serious problem. These losses often occur in porous or fractured formations, and once the drilling fluid is lost, it can be difficult and expensive to regain control over...

... Abstract This paper discusses how a low permeability/Fractured carbonate reservoir, has been rejuvenated throughout a new robust development plan supported by Pilot wells performance. Previously this reservoir could not reach its full reservoir potential due to gas recycling through...
