Nonknowledge production – directly connected to knowledge production (Ravetz 1987, Böschen and Wehling 2010) – can be understood as a quiet and subtle tactic (Frederiksen and Himley 2020) to maintain and expand extractive activities, an instrument (Foucault, 1991) that reflects power relations and produces new subjectivities (Frederiksen and Himley 2020). Nonknowledge is something one does not know, regardless of reasons, implications, or the theoretical possibility of “overcoming” this gap (Böschen et al. 2006). Industrial secrets and monopoly of knowledge production are examples present in extraction projects, such as the underground exploitation in the Industrial site of Lacq, in the French Southwest rural region, industrialized since the ‘50s. I argue that the dynamics of nonknowledge-knowledge production have transformed two subjectivities. Firstly, the non-permanent territory characteristics gained a vertical interest (Braun 2000, Elden 2013) from a dismissed tiny and dangerous reserve of gas once to an area with sufficient gas to be safely explored. Secondly, the region vocation, a rural area with an after-gas plan in the ‘50s, to an industrial site able to adapt itself to expand extraction in time and incorporate the climate action. This was possible through a combination of slight gas exploration and underground storage where undesirable wastes, carbon among them, can be definitively stored theoretically. The analysis of the nonknowledge-knowledge dynamic shows how unequal power relations (Henry 2017) are “systematically inscribed” (Jas 2015) in them. And how they reinforce these two subjectivities, allowing extraction to spread in time and deeper territories.
