The developed forward modeling, when embedded in a classification or regression artificial intelligence...

... especially in a very tight and fractured reservoir deciphering multiple fault orientation, which potentially, cancel the anisotropy estimation due to destructive interference. In addition to the presence of drilling induced fractures interfering in with the natural fracture as seen on the BHI. The detailed...

... Abstract The vast shale gas and tight oil reservoirs cannot be economically developed without multi-stage hydraulic fracture treatments. Owing to the disparity in the density of natural fractures and the different in-situ stress conditions in these formations, micro-seismic fracture mapping has...

... included the effect of natural fractures, using the microseismic events location as natural fracture initiation points. Finally, we used cutoff coefficients to further reduce hydraulic fracture geometries to match production data. The results of this work showed a fast and flexible method to estimate...

... Abstract A case study and methodology is presented to shed the light on the different processes followed during the placement of a non-damaging isolation barrier in a group of highly naturally-fractured and vugular gas wells. The temporary isolation aims at isolating the wellbore from...

... and proppant allocation. The production stage analysis can be applied to flow profiling and fracture characterization. The objective of our DTS data analysis approach is to provide an integrated quantitative diagnosis of effectiveness of staged fracturing, and hydraulic and natural fractures with the full...

... grid refinement (LGR) method to overcome the time-intensive computation performance. The model is then coupled with reservoir models using non-neighboring connections (NNCs). Secondly, eight cases are designed using the EDFM technology to analyze the effect of natural fractures, formation permeability...

... geometries. Taking this concept a step farther, actual hydraulic fracture propagation will interact with natural fractures, localized stresses, and each other, creating an even more complex and hydraulic fracture geometry. Presented here is a novel application where the coupling of RTA and numerical...

... is applied to unconventional reservoirs with hydraulic and natural fractures. Our approach relies on cell volumes and connections (transmissibilities) rather than the grid geometry, and thus can be easily applied to complex grid systems. For illustrative purposes, we present applications of the proposed...

... environment, P- and S-wave velocities (5536.7 m/s and 2699.7 m/s) of a core sample containing natural fractures decreases by 8.5% and 8.1% respectively, while both P- and S-wave velocities (6074.1 m/s and 3858.8 m/s) for a intact sample show only ~0.5% decreases. The interaction also causes more than 50...

... analysis of the local stress regime, the shorter fractures were identified as drilling-induced fractures, which should not be incorporated in the modeling of natural fractures. The new results have improved the understanding of the regional fracture system, leading to a more accurate fracture network model...

... Abstract The depletion of producing layers leads to significant stress changes in adjacent targets, especially when complex natural fractures are present. Due to weak bedding interfaces or small stress barriers, hydraulic fractures can easily penetrate neighboring layers, and this further...

In addition to the mechanical strength, the integrity of the caprock from the standpoint of the presence of natural fractures and faults is another essential attribute for a competent seal against fluid flow towards aquifers and surface. Ideally, a caprock unit is laterally...

These fractures represent pre-existing natural fractures stimulated in shear during hydraulic fracturing as well as the hydraulic fractures themselves. Because...
