Abstract: A method involves detecting parameters corresponding to a hydraulic connection between a monitor well and a treatment well. Such method includes hydraulic fracturing a stage of the treatment well to form hydraulic fractures extending into a surrounding formation, where at least a portion of the hydraulic fractures enable a hydraulic connection between the treatment well and the monitor well that is located in the same field as the treatment well or in an adjacent field. The method also includes measuring fluid influx data corresponding to the wellbore of the monitor well during the hydraulic fracturing of the stage of the treatment well, as well as determining one or more parameters corresponding to the hydraulic connection between the treatment well and the monitor well using the measured fluid influx data.

Abstract: A method involves propagating hydraulic fractures in a reservoir. Such method includes creating a low pressure region in an attractor well. The attractor well is proximate to an area in which hydraulic fractures are desired. The method also includes initiating a hydraulic fracturing operation at a treatment well. The hydraulic fracturing operation is initiated so that a fracture network created by the hydraulic fracturing operation is drawn to propagate toward the low pressure region of the attractor well.

Abstract: Methods of generating a parameter realization, for a subsurface parameter, as a function of depth within a subsurface region are disclosed herein. The methods include dividing a subsurface parameter profile for the subsurface region into a plurality of adjacent stratigraphic units. The methods also include splitting each stratigraphic unit of the plurality of adjacent stratigraphic units into a plurality of stratigraphic unit layers. The methods further include determining a layer parameter value range for each stratigraphic unit layer of the plurality of stratigraphic unit layers and for each stratigraphic unit. The methods also include, within each stratigraphic unit layer, selecting a corresponding layer parameter value from within the layer parameter value range. The methods further include generating the parameter realization by assigning the corresponding layer parameter value to the parameter realization for a corresponding layer depth range of each stratigraphic unit layer.

Abstract: A method and a system for volume-based proppant trapping along a fracture surface is disclosed. Hydraulic fracturing involves injecting proppant to ensure separation of the fracture surfaces after the stimulation treatment is completed. The spatial placement of proppant is assumed to be directly related to the fracture conductivity along the hydraulic fracture as well as its connectivity to the wellbore. Fracture conductivity is an important focus of designing fracture treatments since fracture conductivity may be directly related to the well performance. Thus, improving one or more aspects of proppant placement, such as determining the optimal type, size and/or concentration of proppant(s) may enhance fracture conductivity and in turn improve well performance. In order to understand the placement of proppant in the subsurface, a volume-based proppant trapping model is used. The volume-based proppant trapping model may factor in parameters associated with the subsurface, parameters associated with the proppants, and user parameters, such as the total volume of proppant along the fracture surface, thereby assisting in hydraulic fracturing.
