Acidizing stimulation is a critical part of maintaining an oil or gas well. In the extraction industry, well stimulation is a popular technique used when permeability is low. Other times, it is used when an oil or gas well has fallen into the under-productive category and needs a powerful boost.
The end result of acidizing stimulation depends purely on the reservoir, quality, and types of acids used, additives, and formations. Regardless of the situation, acidizing is the preferred method in the petroleum industry due to its high applications and significant compatibility with most reservoir types.
Benefits of Regularly Acidizing Wells
The use of acid treatments to enhance well productivity has been in practice for about 120 years. So, before you toss the idea of reservoir acidizing aside, take a look at these four benefits of well stimulation.
The primary reason why an oil and gas company would want to use well acidization is to preserve the life of the well. When an oil or gas well is maintained properly, the useful life of that well is extended, and more resources can be extracted before moving on to a new (or younger) site.
Another benefit of regularly stimulating wells lies in improved efficiency. Even if the reservoir is still full of resources and not nearing the end of its lifespan, debris and sediment can lower its efficiency. So, the process of pumping acid into the well dissolves rocks or any loose debris that live along the contours of the well or is floating somewhere in-between.
Lowers Potential Costs
Imagine if your reservoir became clogged or completely unusable? You’d have to spend hundreds of dollars to solve a problem that could have been prevented via proper maintenance and acidizing.
Alternative to Fracturing
While acidizing and hydraulic fracturing may be used in tandem in some cases, acidizing stimulation may be a better method on its own. For example, acid may be more effective at releasing oil deposits in areas with high tectonic activity. It might also be more beneficial if high-pressure water injections prove to be too complex for the situation.
PureLine’s Acidizing Solution
Our methodology for acidizing oil and gas reservoirs breaks the traditional cycle. At PureLine, our enhanced acidization well stimulation uses chlorine dioxide, a solvent, and nano surfactant along with hydrogen chloride.
We use chlorine dioxide because it oxidizes the hydrogen sulfide in the solution to form hydrogen sulfide and soluble S04-2 ions. Then, chlorine dioxide penetrates the biomatrix. Iron sulfide oxides to soluble Fe+3, Cl-, and S04-2.
Because the iron sulfide oxides to iron sulfate, it is still soluble when the pH normalizes, and it will not precipitate. Additionally, hydrogen sulfide will completely oxidize thanks to the chlorine dioxide in the solution.
When your oil and gas well is back up and running, you’ll find the sulfur compounds converted to soluble sulfates, and the biofilm has disappeared. Contact us to reap the benefits of our acidizing solution.
