nanoActiv® in an Energized Huff ‘n Puff
nanoActiv® HnP, powered by Messer Boost-EOR™ Solutions, is a multi-spectrum treatment for vertical and horizontal wells suffering from declined production with restrictions to fluid flowing into the wellbore. The treatment enables the recovery of hydrocarbons to be accomplished faster, more completely, and with longer efficacy than existing options on the market today.
A Productive Collaboration
Messer Americas and Nissan Chemical America Corporation have joined efforts to enhance downhole performance by combining nanoActiv® with a carbon dioxide (CO₂) or nitrogen (N₂) application method.
Nissan Chemical’s excellence in industrial nanotechnology and Messer’s expertise in job design and technical services in oil and gas well remediation and restimulation, combine to provide maximum techno-economic production results in today’s market.
A Powerful Combination
Combining properties of gas and nanoparticles creates a unique, synergistic treatment that addresses several potential production issues simultaneously. The gas helps remove debris, fines, and other matter and stimulates the well with pressure, while driving the effective distribution of the nanoActiv® particles to deeper parts of the formation. In cases where the gas is miscible, it also contributes to mobilizing crude oil due to swelling and viscosity reduction.
nanoActiv® nano-sized particles penetrate further and more thoroughly permeate the natural fracture network than traditional remediation or restimulation technologies. These particles produce a Brownian-motion, diffusion-driven mechanism, known as disjoining pressure, resulting in longer and more complete production efficacy. Field application data validates that particles pushed with Messer gas produce significant and sustained improved hydrocarbon recovery.
Application
Our solution is a prescribed, well remediation treatment (Huff ’n Puff) consisting of three phases: injection, soaking, and production. Because of the synergies between the nanoActiv® and Messer gas, the soak times can be dramatically reduced from traditional HnP treatments. Depending on the type of formation, well history, and identified issues, a specific treatment plan is prescribed.

For a successful treatment, appropriate screening of candidate wells is the first step. Messer Americas and Nissan Chemical America will work with operators on candidate identification before prescribing a recommended treatment plan.
| Production | Good initial production (IP) with decline curve that indicates wettability issues. Current production <20% of IP and >5-10 BOPD or 20 MSCF |
| Field Data | Overall well performance should be on par with other wells in the field. |
| Treatments | Acid and other chemical treatments may negatively impact properties of nanoActiv®. |
| Well Equipment | To be in good mechanical condition. |
| Water | A high content of salts (e.g., KCl) and TDS may negatively impact nanoActiv®. |
| Water Cut | <80% (N2), <90% (CO2) |
| Net Pay Zone | <100 ft (30 m) to optimize for 60-90 days payback. |
| Porosity | Conventional >8%; Unconventional >4% |
| Oil | Oil gravity <30 API it’s recommended to use CO₂. Asphaltene precipitation may be caused by gas injection. |
In March of 2019, Messer Group and CVC Capital Partners Fund VII acquired most of the North American gases business of Linde plc, as well as certain Linde business activities in South America. With over 70 production facilities and approximately 5,400 employees operating in the US, Canada, Brazil, Colombia, and Chile, Messer today is one of the leading industrial gas companies in North and South America. Messer represents a USD $3 billion global enterprise with presence in the Americas, Europe, and Asia, together with Messer Group. To learn more, visit www.messer-us.com.
