Acid Systems Flier

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.

Maximize oil well production with acidization. Learn how targeted techniques can reduce decline curves, enhance recovery, and extend well life.

To optimize reservoir management, it is essential to develop a deep understanding of the reservoir’s characteristics and behavior. This involves analyzing geological formations, fluid properties, and reservoir pressure. 

Advanced techniques such as well simulation and modeling allow operators to predict performance accurately and craft effective production strategies tailored to the reservoir’s unique features.

Oil wells naturally experience a decline in production over time. However, a steep decline curve early in a well’s lifespan often indicates that the [well could benefit from well stimulation](https://petroplex.com/resources/signs-that-your-well-could-benefit-from-well-stimulation). Early identification and timely action can make a significant difference in maximizing production efficiency and extending the productive life of the well.

Here are proven methods to keep production at its highest level for as long as possible while safeguarding your investments.

## Reducing Decline Curves With The Role of Acidizing 

[Acidizing](https://petroplex.com/resources/acidizing-101-a-basic-guide-to-oil-well-stimulation) has been a cornerstone of well enhancement for over a century. This process dissolves formation damage and restores flow pathways by removing scaling, mineral deposits, and other obstructions. In carbonate formations like those in the Permian Basin, acid treatments are particularly effective at increasing permeability and extending productive well life.

* **Quick ROI**: [Petroplex’s tailored acid stimulation techniques](https://petroplex.com/media/acid-systems-flier_file.pdf) deliver measurable results, such as a 32 BOPD average uplift within 60 days and an incremental revenue increase of $151K.
* **Enhanced Recovery**:By targeting damaged or obstructed areas, acidizing stimulation treatments ensure your well performs at its peak potential.

## Key Strategies to Sustain Production

### Increased Pressure Monitoring

When increased pressure is required to maintain consistent output, this is often a sign of restricted flow pathways. Addressing these issues early with **well-stimulation** can prevent long-term damage and costly repairs.

### Regular Formation Analysis

Conducting routine formation analysis helps identify when **acidizing stimulation treatments** are needed to dissolve blockages and restore flow efficiency.

### Proactive Scaling Management

Mineral scales such as calcium carbonate and iron sulfide can drastically reduce production rates and damage equipment. Periodic descaling through **acidizing treatments** protects your wellbore and prolongs the life of your pumps and tools.

### Protecting Equipment

High-quality materials and regular maintenance are essential to prevent premature equipment wear. Combining this with targeted **well stimulation** ensures consistent performance and minimizes downtime.

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.
