Integrated data analysis approach to select artificial lift method using machine learning.
The optimisation of artificial lift (AL) selection in the oil and gas industry stands as a critical endeavour, directly impacting production efficiency, cost-effectiveness and overall operational success. Traditional AL selection methods rely on engineers' time-consuming field data analysis, which …

A novel framework for acoustic diagnostic of artificial lift system for oil-production
Oil extraction on many reservoirs requires the use of rod pump systems to pump the fluid to the surface. A longstanding challenging issue in the operation of rod-pump system is the ability to determine the downhole pump conditions based on the knowledge of a finite set of measurables at the top. A …

Application of Time Series Analytics to Assess Performance of Artificial Lift Systems Deployed in Coal Seam Gas (CSG) Wells
Artificial Lift Systems (ALS) play a crucial role in producing natural gas from Coal Seam Gas (CSG) wells in Australia. These systems are employed in over five thousand wells located in the Bowen and Surat Basins of Queensland. Operators face significant challenges in managing and maintaining …

Downhole Gas Separator Performance in Sucker Rod Pumping System
… a sucker rod pump has been a major concern for artificial lift designers for a long time. One way to reduce the amount of gas entering into the pump is to use downhole gas separators. The main purpose of these devices is to facilitate agglomeration of gas bubbles so that they migrate upwards and …

Gas lift optimization utilising automation gas lift valve
Gas lift is one of the most common forms of artificial lift, particularly for offshore wells. This is due to its relative downhole simplicity, flexibility, reliability, and ability in operating over a wide range of flow rates with the limited well head space. Generally, Gas lift optimization can …

Integrated multiphase flow modeling in wellbore for downhole pressure predictions
… paves the way for the design and optimization of artificial lift processes that require knowing the location and amount of liquid loading.

Gas lift optimization and flow instability
Gas lift is an artificial lift method used in the oil industry to lift reservoir fluid to the surface, by supplementing the reservoir pressure when it is depleted or insufficient. During oil production, this method can be affected by two-phase (gas-liquid) flow instability within the production …

The effect of gas on multi-stage mixed-flow centrifugal pumps
The production from an oil reservoir is a mixture of liquids (oil and water) and gas, and is often maintained by using a pump placed in the well to ensure a continuous flow to the surface. Electrical Submersible Pumps consist of stacked centrifugal pump stages, each comprising a bladed impeller …
