自2019年11月以来，巴肯页岩油气储量年均下降6%。近年来，吞吐式采油技术通常被认为是非常规油气储量最具成本效益的方法。然而，一项已在美国多个盆地得到验证并于2021年首次扩展到巴肯的新型生物技术已显示出非常有前景的效果。完整的论文提供了在多口井进行的试点研究的详细信息，展示了该方法的潜力。
生物表面活性剂是一类多功能表面活性剂，其分子结构复杂独特，具有多个活性位点和3纳米胶束，能够轻松渗透许多与二氧化碳相同的孔隙，已被证明在石油流动方面非常有效。据报道，生物表面活性剂的成功应用使阿巴拉契亚、二叠纪和威利斯顿盆地的产量显著且持续地提升。
对中巴肯地区三口 1 英里水平井（Frink、Woessner 和 Neilsen）的储层样品进行了分析。
Since November 2019, the Bakken shale play has experienced a decline of 6% annually. In recent years, huff ’n’ puff enhanced-oil-recovery techniques typically were regarded as the most cost-effective methods for unconventional plays. However, novel biotechnology, proven in multiple US basins and expanded to Bakken for the first time in 2021, has shown very promising results. The complete paper provides details of a pilot study conducted on multiple wells showcasing the potential of this approach.
Biosurfactants are a class of multifunctional surfactants that are proving effective in oil mobilization because of their complex and unique molecular structures, with multiple active sites and 3-nm micelles, allowing effortless penetration of many of the same pores as CO2. The successful application of biosurfactants has been reported with significant and sustained uplifts in production in the Appalachian, Permian, and Williston Basins.
Reservoir samples were analyzed from three 1-mile horizontal wells in the Middle Bakken: Frink, Woessner, and Neilsen.
