Research on Downhole Plunger Position and Pressure Temperature Detection of Plunger Gas Lift System

Installing Plunger Lift Systems In Gas Wells

In mature gas wells, the accumulation of fluids in the well can impede and sometimes halt gas production. Gas flow is maintained by removing accumulated fluids through the use of a beam pump or remedial treatments, such as swabbing, soaping, or venting the well to atmospheric pressure (referred to as “blowing down” the well). Fluid removal operations, particularly well blowdowns, may result in ...

A Plunger Apparatus for Relativistic Radioactive Beams

Nuclear structure investigations with radioactive beams are at present one of the most interesting and active fields in nuclear physics. Absolute transition probabilities are of crucial importance for these studies which can be directly deduced from the lifetimes of excited levels. The aim of this work is to investigate the feasibility of Doppler shift methods to measure level lifetimes of exot...

Echo State Networks for data-driven downhole pressure estimation in gas-lift oil wells

Process measurements are of vital importance for monitoring and control of industrial plants. When we consider offshore oil production platforms, wells that require gas-lift technology to yield oil production from low pressure oil reservoirs can become unstable under some conditions. This undesirable phenomenon is usually called slugging flow, and can be identified by an oscillatory behavior of...
