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.

HnP Application Steps
 

nanoActiv® HnP · Oil Production

Austin Chalk Formation, Frio County, Welss A & B

Data from two Austin Chalk and two Buda wells in Frio County, Texas. These wells were remediated using a nanoActiv® HnP treatment where nanoActiv® HRT was injected into the reservoir and pushed further out by N2 to allow even deeper penetration.

Austin Chalk Formation · Well A (low dosage)

nanoActiv® HnP pre- and post-treatment comparison after 180 days of cumulative production. Cumulative oil production increased 12%.

Austin Chalk Formation · Well B (high dosage)

nanoActiv® HnP pre- and post-treatment comparison after 180 days of cumulative production. Cumulative oil production increased 174%.

 

nanoActiv® HnP · Oil and Gas Production

Buda Formation, Frio County, Wells A, Oil
Buda Formation, Frio County, Wells A, Gas

Buda Formation · Well A · Oil (high dosage)

nanoActiv® HnP pre- and post-treatment comparison after 690 days of cumulative production. The well continues to produce 3× BOPD more oil.

Buda Formation · Well B · Gas (high dosage)

nanoActiv® HnP pre- and post-treatment comparison after 690 days of cumulative production. The well continues to produce 3.3× MCFD more gas.


Numerous factors affect the performance of an oil well—the geology, the number and size of treatment stages, the choice of additives, etc. nanoActiv® HnP treated wells have shown meaningful performance improvement versus comparative wells from the same operators. While no single technology or treatment can account for the entire performance of an oil well, the effects of nanoActiv® HnP are significant and compelling.

 

nanoActiv® HnP · Well Treatment Screening

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.
