Interwell interference is a ubiquitous concern in shale reservoir development that results in declines in productivity. It mainly appears when a high number of closely spaced parent/offset and child/infill wells are placed in the shale producing zone to stimulate hydrocarbon production. Its consequences become risky when multi-branch horizontal infill wells are employed through massive (and multi-stage) hydraulic fracturing. This review aims to give a comprehensive and applied insight into interwell interference in shale reservoirs. It starts with the root causes and contributing factors, followed by a discussion of various forms of well-interference. Furthermore, different monitoring methods along with detection strategies are highlighted. Numerical approaches have also been explained to understand the fluid flow and geomechanics involved in the interwell interference. Later on, various mitigation techniques are highlighted. Finally, suggestions for future research needs to address the current challenges are discussed.

井间干扰是页岩油藏开发中普遍存在的问题，会导致产能下降。它主要出现在页岩生产区中放置大量间隔很近的母井/偏移井和子井/加密井以刺激油气生产时。当通过大规模（和多级）水力压裂采用多分支水平加密井时，其后果变得危险。本综述旨在对页岩储层中的井间干扰提供全面的应用见解。它从根本原因和促成因素开始，然后讨论各种形式的油井干扰。此外，还强调了不同的监测方法和检测策略。还解释了数值方法以了解井间干扰中涉及的流体流动和地质力学。稍后，重点介绍了各种缓解技术。最后，讨论了未来研究需要解决当前挑战的建议。
