Discover how acidizing boosts oil well production. Learn how Petroplex’s innovative techniques enhance permeability and remove blockages in the Permian Basin.

If you’re in oil and gas production, you know that there’s one metric that trumps all others: Barrels of Oil Per Day (BOPD).

The good news is that you’ve got options when it comes to well stimulation, you don’t have to cap your well prematurely. There are effective solutions for well stimulation that provide excellent ROI.

## What is well stimulation?

If you are looking to uplift BOPD, well stimulation is an attractive option. Well stimulation is the term given to describe the various techniques that can be used to restore or enhance the production of oil or gas from a reservoir.

Hydraulic fracturing (fracking) and [acidizing](https://petroplex.com/services/acidizing) are two of the most common methods for well stimulation that help create pathways for oil or gas to flow more easily, ultimately increasing the overall production of the well.

## What is acidizing? 

Acidizing is a well stimulation technique that injects a hydrochloric acid solution into a well — this process is Petroplex’s expertise. Acidizing dissolves, scaling and carbonate formation fill in a wellbore that restricts the flow of oil and gas. Acidizing is particularly effective in the Permian Basin because of the widespread carbonate rock formations in the region. Calcium carbonate fill and formation scaling reacts readily with the acid, dissolving minerals and creating new flow pathways within the reservoir rock. This increase in permeability significantly improves the well's productivity and allows for easier oil and gas extraction.

## Why use acidizing?

* **Increase Production**: By cleaning or enhancing the flow paths, acidizing can significantly boost the production rate of an oil or gas well.
* **Remove Blockages**: Over time, wells can become clogged with scale, carbonate formation fill, or other debris. Acidizing helps dissolve these blockages, restoring the well's productivity.
* **Enhance Reservoir Contact**: For formations with low permeability, acidizing can increase the contact between the well and the reservoir, allowing more hydrocarbons to be extracted.

## What is the acidizing process?

Whether you need a well cleanout or a proactive rigless treatment, we employ the same process, designing the acidizing job for your specific well to ensure optimal uplift results. Our goal is to know your well from top to bottom so we can tailor our acid-engineered systems to maximize its performance.

Maximizing Production: Strategies for Acid Well Stimulation

Permian Wolfcamp Overview

Petroplex Brochure

Petrosol Product Sheet

Discover how acid-diverter treatments can revive declining Permian Basin oil wells and boost production with targeted horizontal stimulation.

As wells mature and available acreage dwindles, boosting output from existing assets has never been more vital. Acid-diverter systems are proving to be a promising approach in the [Permian Basin](https://www.eia.gov/maps/pdf/EIA-Permian-Part-II.pdf), addressing two key issues at once.  Not only does incorporating acid-diverter systems during workovers mitigate scale buildup in the wellbore, but it has also been shown that these systems can improve inflow profiles.

Why are inflow profiles so important to well stimulation? An inflow profile is essentially a map of how much fluid is entering the wellbore at different points along its length. Understanding and controlling inflow profiles is crucial for optimizing well performance and maximizing oil and gas production.

Poorly balanced inflow profiles signal that oil is being left behind in under-drained sections of the reservoir. Conversely, a smoother, more evenly distributed inflow profile means more zones of the well are contributing, and your well is experiencing less channeling. With less channeling, you’ll see ongoing production gains across the length of the well.

In this blog, we’ll explore how custom acid-diverter treatments deliver sustained production gains in horizontal oil wells.

## The Challenge of Declining Production

 As wells age, operators routinely observe sharp drops in flow rates and bottom-hole pressure. Conventional acid flushes can restore performance. However, repeat treatments are often needed. Additional treatments can raise costs and operational complexity — a hurdle that proactive diversion strategies are designed to overcome.

## Innovative Acid-Diverter Methodology

Optimizing uplift requires a data-driven approach and close collaboration with [acidizing](https://petroplex.com/services/acidizing) experts. Key steps in a diverter-enhanced acid job include:

* **Formation and Production Analysis** — Evaluate zone intervals, pressure histories and scaling tendencies to tailor acid volumes and diverter placement
* **Laboratory Compatibility Testing** — Mix candidate acid blends with formation, crude and simulated iron contents at down-hole temperatures to prevent emulsions or sludge formation.
* **Diversion Agent Selection** — Assess mechanical options (such as ball sealers or plug-and-packer tools) versus chemical gels for cost effectiveness and ease of deployment

## How to Measure Success

Horizontal wells introduce complexity with extended laterals and multiple perforation clusters. However, consistent pressure jumps during post-flush periods confirm uniform diversion and signal effective well stimulation across all zones. This means the acid treatment is being evenly distributed throughout the entire horizontal section, so every part of the well gets a proper “cleaning,” not just the easiest spots.

## Why Freshwater Gel Pills Are a Game-Changer in the Permian Basin

At [Petroplex](https://petroplex.com/), we’ve had great success with freshwater gel pills, and our testing demonstrates that this method stands out among diversion agents. We’ve found they are an excellent choice due to their:

* **Cost Efficiency** — Lower material and operational expenses than mechanical diversion tools or specialty salts.
* **Reliable Degradation** — Lab-validated breakers ensure gels flush completely, restoring permeability without residue.
* **Scalable Deployment** — Simple mixing and pumping protocols allow repeatable staging across various well geometries.

We know that acidizing is effective and produces quick ROI’s, especially for wells in the Permian Basin. But as the old saying goes — timing is everything.

How do you know that your well would benefit from well stimulation? What metrics indicate that an acid treatment is needed? 

While reduced production rates (beyond the expected production decline curve) almost always indicate that there is formation damage, there are other signs that can help you determine when an acid stimulation treatment can be used.

## How do you know when to stimulate a well?

### Increased Pressure Differential

If there’s a noticeable increase in the pressure needed to maintain the same production levels, this can signal restrictions in the flow pathways, often due to scaling, emulsions, or formation fill.

### Formation Damage Indicators

Damage from drilling fluids, completion fluids, or fracturing can block the formation's natural flow channels. Acidizing is particularly effective in dissolving wellbore restrictions in carbonate formations like those found in the Delaware and Midland Basins.

### Scale or Buildup in the Formation or Wellbore

Mineral scales, such as calcium carbonate or iron sulfide, can build up over time, especially in carbonate reservoirs and sour gas wells. Acidizing can dissolve these deposits, helping restore flow. Descaling can also improve the longevity of your pumps and equipment. 

### Reduced Permeability Near the Wellbore

It is common for the pore space near the wellbore to become damaged over time due to fine particles, chemical reactions, and reservoir pressure differences. If analysis indicates reduced permeability via pressure testing or core samples, acidizing is likely an effective solution.

### High Skin Factor

Skin factor is a metric used in well performance analysis and a parameter in the Darcy Flow Equation. This is a fundamental law in physics that describes the flow of a fluid through a porous medium. Without getting too technical, this data is used to account for the difference in theoretical flow rate versus the actual observed flow rate. A high skin factor indicates resistance to fluid flow near the wellbore. So, it’s good to note that when the skin rate is high, the well is a good candidate for an acid stimulation treatment.

### Historical Analysis

Analyzing well logs, production data, and laboratory examination of formation and oil/water samples can provide a clearer indication of when acidizing should be deployed and what techniques should be used.

## A Proven Process for Well Stimulation

Ultimately, it is not just one data set or site sample that indicates when and how you should approach acidizing — and that’s why an experienced partner can help you assess the best path forward for your well. 

Whether you need to increase permeability or descale your formation, we use a [time-tested process](https://petroplex.com/media/petroplex-brochure_file.pdf) to design the acidizing job for your specific well and KPIs.

Signs That Your Well Could Benefit from Well Stimulation

Maximize oil well production with a custom acid blend. Learn how targeted techniques can extend well life and enhance production.

In the oil and gas industry, [well stimulation](https://petroplex.com/resources/maximizing-production-strategies-for-acid-well-stimulation) is crucial for maximizing production, and [acidizing](https://petroplex.com/services/acidizing) plays a significant role in this process. However, not all acid treatments yield the same results.

A customized acid mix tailored to your well’s specific geological and environmental conditions needs can make all the difference in achieving long-term productivity. Understanding the chemical composition of the acid mix is key to optimizing well performance and preventing costly issues.

## The Importance of Acidizing in Well Stimulation

Acidizing is a [well-stimulation technique](https://petroplex.com/resources/acidizing-101-a-basic-guide-to-oil-well-stimulation) that enhances permeability by dissolving scaling deposits and carbonate formation fill. It is commonly used in carbonate reservoirs and sandstone formations to improve hydrocarbon flow. However, an off-the-shelf acid blend may not effectively address the unique challenges presented by different formations. This is where a customized acid mix comes into play.

## Why Chemical Composition Matters

The effectiveness of an acidizing treatment depends on the precise balance of acids, surfactants, corrosion inhibitors, and other additives. A well-designed acid mix ensures:

1. Optimal Penetration – A custom acid blend, such as Petrosol (a proprietary acidizing system developed by Petroplex), improves acid penetration by removing oil-coated scaling and carbonate fill downhole while breaking emulsions and reducing surface tension. This allows the acid to reach deeper into the formation, enhancing permeability and hydrocarbon recovery.
2. Controlled Reaction Rates – Different formations require specific acid strengths and reaction rates to prevent excessive dissolution or unwanted byproducts that could damage the well structure.
3. Reduced Formation Damage – Without the right additives, acid treatments can cause issues such as emulsions, asphaltic sludge, or unwanted precipitation. The inclusion of dispersants and surfactants helps to suspend insoluble particles and remove blockages effectively.
4. Extended Production Life – A tailored acid mix maximizes post-treatment productivity. Studies have shown that advanced chemical technologies, such as Petrosol, can lead to an 82% increase in post-60-day oil production, compared to conventional acidizing methods.
5. Prevention of Corrosion and Scaling – The right chemical inhibitors protect the wellbore and downhole equipment from acid-induced corrosion, ensuring long-term well integrity.

## Petrosol Advantages

Petrosol offers several key advantages over standard acid treatments:

* Solvent/Low Surface Tension Properties – Effectively removes oil-coated scaling and carbonate formation fill, allowing for better acid penetration.
* Paraffin Removal – Contains dispersants and solvents that help remove and disperse paraffin in oil, preventing blockages.
* Enhanced Water Block Removal – Its superior surfactant foamer/detergent properties help eliminate water blocks and foreign materials from the wellbore, improving hydrocarbon flow.
* Suspension of Insoluble Fines – Functions as a suspension agent that keeps insoluble fines from settling in flow channels, reducing formation damage and maintaining flow efficiency.

## How Custom Acidizing Solutions Improve Well Performance

Petrosol combines surface-active additives to improve wettability, reduce surface tension, and remove organic deposits. Additionally, it enhances the ability to treat oil-wet formations, significantly increasing production rates compared to standard acid solutions.

## The Role of Gel Diversion in Acidizing Efficiency

In addition to using Petrosol, pumping an acid job in stages with a gel diverter allows the acid to penetrate deeper into the formation, increasing treatment effectiveness at minimal added cost.

* Gel Diversion Systems: Gel pills (typically 15-25 BBL of ~70 CP viscosity gel) are pumped between acid stages. This temporarily seals perforations or fractures that absorbed the previous acid stage, increasing pressure and directing subsequent acid treatments to under-stimulated zones.
* Multi-Staged Acid Treatments: A standard acidizing job may include 4-5 acid stages (e.g., 60 BBL 15% HCl with Petrosol) interspersed with 4-5 gel stages (15-25 BBL each). This method ensures uniform treatment. The gel includes a pre-mixed breaker for predictable dissolution and effective well cleanup.
* Gel Synergy with Petrosol: The combination of Petrosol’s enhanced penetration and optimized gel diversion creates a powerful synergy. Field data shows that treatments using both Petrosol and gel diverters resulted in an 86% higher increase in BOPD compared to treatments without both. This underscores the importance of pairing advanced additives with effective diversion techniques.

## Petroplex: The Permian Basin’s Go-to Partner for Well Stimulation

A customized acid mix is not just an enhancement — it is a necessity for maximizing well-stimulation efficiency. The right chemical composition ensures deeper penetration, controlled reactions, minimal formation damage, and extended production gains. Whether dealing with tight oil formations or carbonate reservoirs, investing in a specialized acidizing treatment like Petrosol can provide a competitive edge in oil and gas recovery.
