... Abstract A general assumption in unconventional development is that horizontal wells in close vertical proximity tend to interfere with each other, causing the ultimate recovery of each well to be diminished to the extent that their stimulated rock volume (SRV) overlaps. However, recent...

... the effect of the stimulation strategy on fracture interferences and the potential for mitigating them. Introduction Several processes in nature involve fluid-drive fracturing, both taking place spontaneously and as engineering applications. Most of these processes relate to geosciences and civil...

... the completion of one of the child wells. The production interferences observed along the fractures in the horizontal wells were measured with water-oil tracers. There are comments about the imbibition effect and the results are compared with analogous fields in a similar Vaca Muerta oil window where...

... interference effects. The degradation is observed to be 1.3 to 1.9 more severe if a well is fully bounded as opposed to singly bounded. Implementing a staggered (also known as modified zipper) configuration results in considerably better performance, particularly for short-term recovery. fluid dynamics...

... production interference as a function of wells per section, completion parameters, and confinement inside of each GSA. These results were then validated via integrating multiple data sources such as time lapse geochemistry (TLG), downhole pressure gauge data, rate transient analysis (RTA), microseismic, etc...

... to understand the conductive half-length (Chu et al. 2018) and the implications of this number on expected communication between primary horizontal targets across the Midland Basin. Methods/Procedures/Process CPG is an analytical method of quantifying and categorizing well interference which has been...

... Abstract Well interference in unconventional reservoirs has been a pivotal issue due to its significant impact on well productivity, estimated ultimate recovery, and field development economics. Their detection and quantification of the future production profile of the frac-hit affected well...

... fluids and stimulation fluids were produced simultaneously. Modeled well interference is in good agreement with collected fluid/oil tracer data. The novel workflow presented retains the values inherited from diagnostics and minerology calibrated petrophysical data, and fracture geometry from physics...

This paper outlines the implementation of three multi-disciplinary methods and best practices that when used...

... and horizontal interferences between horizontal wells targeting different landing zones and estimating their effective drainage height, production allocation by geochemistry, chemical tracers, pressure interference analysis, and well performance techniques were integrated into several well pads in the oil...

... Abstract Determining optimal well spacing/stacking configurations in multi-bench unconventional reservoirs requires a robust understanding of the drained rock volume (DRV) and resulting interference between multi-well development. Many studies focus on singular workflows or data acquisition...

Technologies used in this study include frac diagnostics with fiber and pressure gauges, well interference tests, time-lapse...

... Abstract To evaluate well connectivity and the impacts on well spacing and long-term production in Bakken, ConocoPhillips has conducted many interference tests which involved alternatively flowing or shutting in adjacent wells in the test pads. This paper will focus on the quantitative...

... Abstract Analysis of well interference tests from an extensive data acquisition project in the Bakken shale has shown that wells completed in the Middle Bakken (MB) and Three Forks (TF) can be fully communicated as the result of enhanced fracturing treatments and well spacing designs...

... Abstract Rate Transient Analysis (RTA) is widely used in the industry to understand the Stimulated Reservoir Volume (SRV) of horizontal wells for forecasting and for comparing well performance. However, significant well interferences are observed while using SRV dimensions obtained from...

..., and a larger HF would lead to a more rapid warm-back. Stress shadow and fracture interference effects (e.g., fracture hits) are detected from temperature variations. Therefore, temperature data can be used to infer HF, SF and NF geometries and distributions and provide information about fracture growth...

Other, more simplified methods, lack the ability to model well-to-well interference effects, either because they rely on empirical relationships or simplified analytical single-well models. This paper presents an alternative...

Our hypothesis based on these observations is that pressure variation among benches and vertical phase segregation cause the hydrocarbons in the drainage area...

Data from Wilson show most oil originates in the drilled interval, and that contribution increases over time. Oil...
