Improving the ability of well intervention technologies, such as hydraulic fracturing and remediation, to effectively and efficiently stimulate productivity remains a challenge. Steep production declines after high initial production and less-than-optimal fracturing results indicate that significant proppant quantities are not reaching the available induced or natural fracture network. Nissan Chemical America Corporation (NCA) introduced nanoActiv HRT, a high-efficiency hydrocarbon recovery technology well-intervention additive package, to address this challenge. NCA’s nanoActiv HRT particles penetrate beyond the induced fracture network on a nanoscopic scale, rapidly and extensively saturating a significant portion of the natural fracture network. Producing a diffusion-driven mechanical process known as “disjoining pressure,” nanoActiv HRT particles deliver long efficacy in the recovery of hydrocarbons, fragmenting them into smaller droplets and enabling an efficient backflow to the wellbore. Over the past 2 years, this new technology has been applied in more than 45 Permian Basin wells in several reservoirs (Wolfberry, Wolfcamp B, Wolfcamp Sand, Brushy Canyon, Woodford, and San Andres) and also in North Dakota (Three Forks, Bakken, and Codell-Niobrara). In these applications, nanoActiv HRT has significantly reduced decline rates after stimulation while consistently delivering higher oil cuts and gas/oil ratios in conventional and unconventional reservoirs.
