ReamerHow SVES Oilfield Supply Co., Ltd Can Help You Boost Your Production in Pre-Salt Oil Fields

Pre-salt oil fields are among the most challenging and rewarding exploration targets in the world. They contain huge reserves of high-quality oil trapped under thick layers of salt, which require advanced technology and expertise to access. 

However, producing oil from pre-salt fields is not easy. As the fields mature, the output of single wells declines, and some wells enter intermittent production or even stop production. This leads to waste of oil and gas resources, increased cost of maintenance, and environmental risks.

To overcome these challenges, you need a reliable andJars experienced oilfield service provider, such as SVES Oilfield Supply Co., Ltd. We have been providing high-end oilfield services for over 20 years, specializing in oil and gas upstream and downstream industrial as well as geothermal drilling. We have a strong track record of delivering quality products and services to our customers, such as Sinopec, PetroChina, CNOOC, Shell, BP, ConocoPhillips, CACT Operators Group, DEVON, Far East, EOG, Sunwing Energy,Asia drilling Nobel Oil, PTTEP，Nucoastal，etc.

In this blog post, we will introduce you to a new technology that can help you increase your production in pre-salt oil fields: the dual-cavity mixed flow stimulation technology. We will also explain how SVES can help you implement this technology and achieve your goals in the oil and gas industry.

What is dual-cavity mixed flow stimulation technology and how does it work?

Dual-cavity mixed flow stimulation technology is a novel technique that can reduce the back pressure of oil wells and increase the production of single wells. It is based on the principle of "double cavity liquid reciprocating drive", which means using two cavities (one for liquid and one for gas) to create a reciprocating motion of the liquid, which in turn drives the gas to flow.

The technology consists of a dual-cavity mixed-flow booster device, which is installed on the well's external transmission line. The device has two chambers: a liquid chamber and a gas chamber. The liquid chamber is connected to the wellhead, and the gas chamber is connected to the gas pipeline. The device also has a valve system that controls the opening and closing of the chambers.

The working process of the device is as follows:

- When the valve system is closed, the liquid chamber is filled with liquid from the wellhead, and the gas chamber is filled with gas from the gas pipeline.

- When the valve system is opened, the liquid chamber is emptied, and the liquid flows to the gas pipeline, creating a pressure difference between the two chambers.

- The pressure difference causes the gas in the gas chamber to flow to the liquid chamber, filling it with gas.

- The valve system is closed again, and the cycle repeats.

By doing this, the device reduces the wellhead back pressure and thus the oil pressure, while maintaining the external pressure. This creates a favorable condition for the oil to flow from the reservoir to the wellbore, and increases the production of the single well.

How can dual-cavity mixed flow stimulation technology benefit you?

Dual-cavity mixed flow stimulation technology has been successfully tested in a pre-salt oil field in Brazil, and the results are impressive. The first test well, H8038, was a typical intermittent production well, with an average daily crude oil output of 13.5 tons before the installation of the device. After the installation and operation of the device, the well achieved continuous production, with an average daily crude oil output of 22 tons, a cumulative oil production of 1,600 tons, and an oil increase of more than 600 tons without considering the natural decline. The yield increase was 62.9%.

The test shows that dual-cavity mixed flow stimulation technology can effectively reduce the production back pressure of oil wells, and prolong the production cycle of oil wells. This can help you achieve the following benefits:

- Increase your oil production and revenue

- Optimize your oil recovery and resource utilization

- Reduce your operating and maintenance costs

- Minimize your environmental impact and carbon footprint
