2020-2-24 The conventional hydrocyclone-based DOWS and gravity separation-based DOWS have their inherent constraints in terms of separation efficiency, cost complexity, failure and controlling. The proposed membrane-based separation addresses all these issues due to its mechanical simplicity and flexibility in selecting disposal zone and geometry.

2004-11-8 example a hydrocyclone oil/water separator is installed below the producing zone in the well. Hydrocyclones have been used for many years above ground for the separation of oil, gas and water. Hydrocyclones have no moving parts and separate substances of different density by centrifugal force. A liquid/liquid hydrocyclone is used in DOWS technology.

2015-8-1 In 2002, a hydrocyclone was patented (Aslin, 2002) for gas–liquid–solid separation by means of the former hybridizing idea which merging the two underflow. Gas, liquid and solid phase were distributed concentric with radius increased, and the feature of the two outlets was tangential. One of them was connected to a debris collector.

2016-10-17 hydrocyclone based liquid-liquid separation processes have only been accepted within the last 10 years. There has been a growing awareness within the oil and gas industry of the importance of effective fluids handling, and in particular the preservation of droplet size, by minimizing shearing forces within the process flow.

the hydrocyclone-type DOWS can handle volume of fluid up to 10,000 bpd compared to the gravity separator-type DOWS which can handle only up to 1,000 bpd (Veil et al., 1999). This work was done to provide more reliable data to support the limited experimental data on LLHCs for separation technology. The objective of the

Minimum water/oil ratio - The DOWS system should be designed so that some water is produced with the oil. Since the hydrocyclone separator is not 100% efficient, it is more desirable to produce some water to the surface than to try to fine tune the system and run the risk that some oil is lost to the injection zone.

2016-3-18 Hydrocyclone-type DOWS have been designed with electric submersible pumps, progressing cavity pumps, and rod pumps. Most of the development work on this type of DOWS was done through several joint industry projects by a Canadian organization, CFER-Technologies. Gravity separator-type DOWS are designed to allow the oil droplets that enter a well ...

2016-11-16 This presentation will discuss the potential use of very small diameter, low-capacity hydrocyclones for downhole oil/water separation. The proposed approach aims to mitigate problems associated with single-stage, high-capacity hydrocyclones. Clearly, a viable DOWS technology would have a significant impact on oil and gas production worldwide.
