The depletion of traditional oil fields is driving the oil & gas industry to explore new exploitation sites previously considered as unprofitable. Deep-sea oil fields represent one of these new areas of exploitation. Well drilling during exploration and production operations generate large quantities of drilling waste whose biological impact on the deep-sea floor remains largely unknown. Because of the harsh abiotic factors characterizing this environment, the evaluation of this impact remains challenging. High hydrostatic pressure is the prominent factor which will affect in-situ biological processes. This review will examine the feedback on the various strategies used to evaluate the biological impact of deep-sea drilling waste deposition as well as the current technological limitations. Given the complexity of this issue, a good perspective strategy would be to trend towards the research and development of more relevant bioassays, especially considering the crucial factor of hydrostatic pressure.
传统油田的枯竭正在推动石油和天然气行业去勘探以前被认为无利可图的新开采地点。深海油田就是这些新的开采区域之一。在勘探和生产作业过程中钻井会产生大量的钻井废物，但其对深海海底的生物影响在很大程度上尚不清楚。由于该环境具有恶劣的非生物因素，因此评估这种影响具有挑战性。高静水压力是影响原位生物过程的突出因素。本综述将考察用于评估深海钻井废物沉积的生物影响的各种策略的反馈，以及当前的技术局限性。考虑到这个问题的复杂性，一个很好的策略是倾向于研究和开发更相关的生物测定法，特别是考虑到静水压力这一关键因素。
