... landing intervals for optimal drainage of the reservoir. In addition, when geochemically derived mobile oil saturation indices are partnered with drainage data, it reveals when intervals may experience depletion. Cuttings were collected in an area well at 20’ intervals, and produced oils were collected...

... the infill well in a geo-informed manner. This would be accomplished by isolating depleted regions, maximizing cluster efficiency, decreasing the required stage count, and utilizing a practical treatment approach to maximize stimulation in the depleted and non-depleted sections of the wellbore. The authors...

... wells (child wells) are drilled and fractured close to those that have already been in production (parent wells). Due to the pressure depletion, the new wells are not as productive as the original ones. The alternatives to deal with this problem are diverse. There is more than one technical-economic...

During completion of the child well(s...

The petrophysical and facies interpretations were revised and refined based on observations from simulation modeling. Multiple conceptual visions...

... Abstract In 2019, a process was developed that uses standard drilling data, obtained on virtually every well, to identify and quantify areas of localized depletion which occur around producing fractures in unconventional shale reservoirs. This data is most often used to mitigate fracture...

The triple-porosity model provided a comprehensive understanding of gas and water contributions per zone across each facies. The study also showed major pressure depletion is limited to the sand channels with higher NTG...

... Abstract In Permian Basin unconventional reservoirs, field production data show that water cuts tend to increase over the long term, mostly driven by depletion. This increase becomes more severe with faster reservoir depletion due to larger completion designs, higher well density, and more...

...). Furthermore, the presence of parent wells (pore pressure depletion) will accentuate the interference by altering fracture geometry and creating asymmetric fractures. In extreme cases, a fracture may only have one wing extended into the depleted zone (Mukherjee et al., 1995). Frac interference has been studied...
