Post# of 1425
Is this the reason for all of the quiet??? We'll see...
David Holcomb, David Holcomb David Holcomb!!!! Nissan Chemical now has TWO patents involving David Holcomb! David Holcomb is working with all three of these companies currently on different aspects of the same goal...significantly improving oil cuts.
Here's the DD...

U.S. Patent No. 10,801,310, entitled, “USING GASES AND HYDROCARBON RECOVERY FLUIDS CONTAINING NANOPARTICLES TO ENHANCE HYDROCARBON RECOVERY” was issued on October 13, 2020. This patent was the result of a collaboration between Nissan Chemical America Corporation, a worldwide leader in nanotechnology, and Messer Americas, a world leader in industrial gases. The inventors are Robin Watts, Kevin Watts, John Edmond Southwell, David Holcomb, Naveed Aslam and Yusra Khan Ahmad. The technology—branded as nanoActiv® HnP—combines Nissan Chemical America’s patented nanoparticle fluids with Messer’s gases. Their collaborative treatment method is a unique energized, fast-turnaround style “Huff ‘n Puff”—incorporating nanoActiv® fluids with a carbon dioxide (CO2) or a nitrogen (N2) gas application to enhance oil and gas recovery.
“The nanoActiv® HnP technology enables the recovery of hydrocarbons to be accomplished faster, more completely, most cost-effectively and with longer efficacy than existing options on the market today,” said Chris Ebeling, EVP, Sales & Marketing, US Bulk at Messer Americas.
“The unique combination of our specially-surface-treated nanoparticles and Messer’s highly effective application method is proving to be valuable for reviving wells, and increasing oil and gas returns,” says NCA Senior Petroleum Engineer, Yusra Ahmad.
“One of the key features of nanoActiv® HnP is the simplicity in executing the treatment, with which operators have been very pleased,” said Robin Watts, Oil & Gas Program Manager, Messer Americas. “We believe this technology will have a significant impact for oil and gas producers worldwide.”
According to Messer’s Oil and Gas experts, a recent Woodford Formation Well – treated with nanoActiv® HnP powered by Messer Americas’ nitrogen – continues to experience sustained daily gas production levels 120% greater than its originally completed initial daily production levels. Another well in the Buda Formation has produced an incremental of 11,600 BOE, and the well continues to produce more than 3x MCFD of gas at ~1,000 days post-treatment. The production improvements provided by the nanoActiv® HnP treatments can give operators a reliable, cost-effective alternative to other re-stimulation/remedial methods and provide a practical, economically viable solution for full field re-development enhanced recovery.

Grassy Creek Overview

Maverick Energy Services – PCT LTD. Catholyte – Grassy Creek Oilfield, Waterflood Improvement Project, Vernon County, MO
PCT Ltd. is working with Maverick Energy Services in Vernon County, Missouri, to use a unique electrochemically produced catholyte to enhance the injectivity, sweep efficiency, and oil production in a modified seven-spot well pattern. This seven-spot pattern #2A is a part of the larger Grassy Creek Oilfield where all seven wells are situated in the eastern part of the field and are closely spaced making them ideal for a field pilot test. These particular wells have not been treated other than by traditional waterflood. (Other wells in Grassy Creek were treated with a steam flood and a surfactant with limited success.) The pay thickness is between 20 and 25 feet for the lower Bluejacket SS and up to 80 feet in the Warner SS. The porosity in the Bluejacket is between 14-16% and 21-24% in the Warner. The permeability is between 20 and 40 md in Bluejacket and between 118 and 687 md (avg. 350 md) in the Warner. The crude oil is moderate to low gravity (19-29 degrees API), and reservoir temperatures average approximately 90 degrees F. The catholyte is produced onsite from special electrotonizing process machinery using clean brine water. It can produce up to 700 gallons per day of 600-700 pm and 600-900 ORP catholyte. Storage is provided for up to 2000 gallons onsite, and a distribution line and pump is tied directly to the 2A seven-spot well injection well(s).
The project is using catholyte which has been initiated with Maverick Energy Services by designing up to an initial 30-day trial using varying volumes of the catholyte. The trial is being preceded by doing production and injection testing with fluorescent tracers on the two injectors (Warner and Bluejacket zones) as well as production tests on wells 2-1 through 2-6 to establish a baseline injection/production rate and pressure (if any since in the past some have gone on a vacuum), and monitoring every 4 hours for two to three days for tracer at each producer.
Once the baseline rates and pressures are established and the producing wells validated with positive or negative tracer shows, then the catholyte will be produced onsite and injected into the two injection wells or one injector depending on the results of the tracer testing for each zone. If all wells are not in communication with the injection well(s), then the issue will be addressed by considering polyacrylamide polymer as a small volume (250-500 gallon) pumped ahead of the next volume of catholyte to help slow breakthrough or channeling to certain wells and allow a more efficient distribution to the other wells. This may or may not be required to provide more uniform distribution of the catholyte in as many producing wells as possible on the seven-spot pattern. Once the injection profile is understood, then 1000 gallons of the (hot) 600-900 ppm catholyte solution will be manufactured and injected into PCT Catholyte separation experiment.
the appropriate 2A injection wells. Then the injectors will be returned to injection of normal brine and monitored on day two with bucket tests performed on each well that is producing, looking for improved oil cut in the WOR as well as any pressure changes. Samples will be collected at each producing well. Then on day three, another 750 gallons (hot) catholyte will be injected followed by putting the well back on injection with clean injection brine water. Injection will continue over the next 24 hours (day four) followed by the production and sample testing protocol as before. This will be followed on the fifth day by another 500 gallons of (hot) catholyte and injection over the next 24 hours to monitor production rates and pressures as well as WOR. If oil ratio begins to increase, then the seven spot can be maintained on injection and repeating repeating the catholyte injection sequence described above over the next several days up to 30 days if necessary. The goal is to prove the catholyte technology for this reservoir type by a markedly improved oil cut after two to four weeks injection of catholyte alternating with injection brine water mix).
The results will be evaluated, and it will be decided that the injection will be continued as catholyte alternating with brine water as may be required to maintain improved oil cut in the water oil ratio (WOR).
