.... The resulting conceptual plumbing diagram ( Figure 1 ) includes three key high-k elements: Cemented Cycle Tops (CCTs) : Cemented, low porosity layers (cycle tops) that are sequence stratigraphically controlled and where open fractures, enlarged by dissolution, and vuggy porosity make up flow paths. Core...

... The previous detailed data collection can be divided by direct measured properties, that are a sizeable, measurable and reliable (if data quality is validated) and simulated/estimated data based on the earliest. In a conceptual way both are highly reliable for the HF parameters for the fracture...

... property simulation. The maximum liquid dropout in Field B is almost half of that one in Field A, characterizing Field B as a lean gas condensate reservoir and Field A as a rich gas condensate reservoir. In addition, almost all wells in Field B are hydraulically fractured, which serves as a method to delay...

..., associated with tight green fields and how these uncertainties are parameterized with the integration of well hydraulic fractures. Uncertainty and optimization workflow has been adopted in a commercial geo-modeler to consider all the associated uncertainties. Structural uncertainty is parameterized using...

... Abstract Tight naturally fractured carbonate reservoirs often show steep rate and pressure declines leading to reduction in apparent well productivity. These declines are influenced by several complex phenomena. Some of these are geometry and density of natural fractures (NFs), matrix...

... be identified based on the well logs directly. Detailed analysis of the borehole images yields additional evidence such as lithofacies and textures in the MTC. The faults and fractures in the MTC can also reveal the controlling factors on the shale gas enrichment. The analogs between the concept model...

... was attended that includes three perforation intervals. The well was completed with a cemented liner in preparation for proppant fracture stimulation. Perforation interval #1 was not fractured. Perforation interval #2 and #3 was fractured in 2 separate stages. Thus, with the help of various dominant...

... These seismic facies have then been used to assist Sequential Gaussian co-Simulation to distribute the fractures between wells. The high confidence fracture lineaments defined in the previous generation of the fracture model have been directly adopted. Abstract A multi-billion-barrel...

... Abstract Understanding the flow behaviour of fractured wells is crucial to operators and service companies in evaluating the effectiveness of stimulation work performed on the well. New insights in modelling of well transient pressure tests in hydraulic fractured unconsolidated sand...

... of in-depth research on reservoir geomechanics and distribution law for natural fractures: 1) The Hydraulic fracture propagation law is not clear; 2) In the process of fracturing, there exists an obvious phenomenon of non-uniform fluid inflow and expansion in various clusters of fractures; 3) Serious...

The Micro-Resistivity image revealed various types of geological features such as the conductive, enhanced, resistive fractures and different bedding plane in addition to different geological textures were interpreted along the well trajectory and was used...

... Under the action of the far-field principal in-situ stress, the natural fracture surface is a closed plane, and is free from tangential slip. The shear stress and normal stress components of the far-field principal in-situ stress acting on the natural fracture surface are calculated as follows...
