Talk Title: Well Productivity Enhancement: From Reservoir Geomechanics to Near-Wellbore Geomechanics


Abstract:


More often, the industry comprehends the necessity of incorporating geomechanical analysis for making decisions at the moment of completing a well or to improve/guarantee a sustained well productivity performance.
Estimated conditions at reservoir scale can mask the dynamic conditions at wellbore scale. A reservoir sand that moves within the elastic domain during depletion, can move within the elastoplastic domain in the near-wellbore region. Depending on rock type and failure localization, sanding, compaction or shear bands can be induced. Consequently, Fracpacks might be excluded as a completion or hydraulic fractures can be impaired. Completions programs might become unreliable when they are based on reservoir stress paths as these do not reconcile with near-wellbore stress paths, which turns out to be difficult to reproduce in the lab.
Field examples are shown indicating how reservoir scale solutions (cumulative strains from drilling and depletion/injection processes) need to be carried to near-wellbore solutions. As one example, skin evolution issues determined from pressure transient analysis are recommend to be tracked along with equivalent plastic strains from near-wellbore geomechanics models. Consequently, pressure ramp ups of wells and ultimate completion schemes (fracpack vs. casing and perf.) can be better implemented. Thus, the need of integrated geomechanical solutions at reservoir and near-wellbore scale becomes the key for well productivity Enhancement.

Talk Title: Salt flow and deformation of reservoir intervals within layered evaporite sequences over geological time scales: Insights from geomechanical forward modeling


Abstract:


Layered evaporite sequences (LES’s) in petroliferous salt basins offer unique challenges in geological structural interpretation, assessment of trap/seal timing, and drilling hazards. Geomechanical forward modeling (GFM) is presented as a powerful technique to assess the likely impact of geological history on the deformation within reservoir intervals in LES. In addition, in areas of active salt tectonics, such models can also be used as directional guides to constrain salt mobility and in-situ stresses within the LES sediments and to complement traditional kinematic techniques, which cannot address the impact of mechanical contrasts within LES on the deformation in sediment intervals.

Talk Title: Utilizing 3D Geomechanics Models to Evaluate and Influence Production and Injection Operations


Abstract:


Geomechanics, which is the engineering evaluation of the interplay between formation stresses, pressure, and mechanical properties within or along a given geometry, can play an important role in optimizing field-life operations. For many reservoirs, the primary driver for geomechanical changes is reservoir pressure change (decreases during depletion or increases during injection), which influence the stress field and, consequently, formation deformation – like stress-dependent permeability changes - and/or failure such as reservoir compaction or well failure. A 3D geomechanics model thus serves as a means to forward predict reservoir geomechanical changes as a function of reservoir management scenario, leading to more accurate and optimized field and production management.

Talk Title: How much do proppants contribute to production in unconventional resources


Abstract:


Proppant is sand or similar particulate material suspended in water or other fluid and used in hydraulic fracturing operations to keep fractures open in unconventional resources (UCRs). Many different proppants have been developed in the energy industry, with different types, sizes, shapes, and applications. While the use of proppants for hydraulic fracturing in UCRs has been dramatically increased in the past decade, how much proppants contribute to production remains unclear. In this work, we present a numerical study using layer cake synthetic models to better understand the relationship between proppants and production. Fracture geometries are calculated using a fracturing simulator with different proppants and then ported into Chevron In-house GeoMechanical Reservoir Simulator (GMRS) for geomechanical analyses and production simulations. We show sensitivity studies of proppant concentration, size and settling on the production for reservoirs with different flow properties. Finally, we develop some understanding on how and how much proppants contribute to production in UCRs.

Talk Title: Geomechanical effects on the efficiency of plug&perf completions in Unconventional wells


Abstract:


The production performance of the unconventional wells is driven by the efficiency of placing many large hydraulic fractures in the drainage volume, often at tight spacing. Some of these fractures are propagated simultaneously, while others are stimulated sequentially. But in both cases, there is a legitimate concern that the stress perturbation will interfere with the process and may result in a less efficient outcome. This talk is concerned with the efficiency of stimulation of multi-cluster plug&perf stages where multiple fractures are stimulated simultaneously.
A major concern with plug&perf completions is to ensure uniform distribution of the pumped fluid and proppant between the clusters. Stress interference is not the only geomechanical phenomenon affecting the outcome. In this talk we will make a case that small-scale near wellbore fracture tortuosity is a more potent threat to the plug&perf completions.

Talk Title: Mapping reservoir stress conditions using hydraulic fracturing microseismicity


Abstract:


 The state of stress of the reservoir is one of the dominant factors controlling the reservoirs response to stimulation as well as the effectiveness of the treatment design. For instance, the hydraulic horsepower, which takes into account the reservoir stress states and pressures, may be sufficient to stimulate certain parts of the reservoir, but any variations in the stress state can result in adverse effects such as damaging nearby wells, out-of-zone growth, and damaging earthquakes. In this study a catalogue of microseismic fracture plane solutions is used to map the stresses onto the microseismic fracture planes and evaluate the states of stress throughout the stimulated rock volume. It will be demonstrated how a suite of geomechanical parameters can be used to identify fracture populations likely to control fluid flow, those that required different stimulation pressures in order to contribute to flow, and the mechanical conditions that favored out-of-zone growth and reactivation of geohazards. Additional observations, such as net wellbore pressure and geophysical logs, are used to calibrate the model as well as to further understand the geological, geomechanical and treatment-related variables affecting the overall stimulated rock volume. The method is applied and discussed in the case of a microseismic event catalogue obtained during the stimulation of two horizontal wells landed in the Eagle Ford, where large variations in fracture patterns as well as geohazards were observed.
