Here, we demonstrate the use of a machine learning framework that can be used to customise each workover configuration such that it optimises PCP run-life, respecting the well's heterogeneity and age. The primary reason for workovers is progressive cavity pump (PCP) system failures. The cost of workovers as well as the associated deferred production may overwhelm the economic viability of the field. The results observed were very close to modelled with a number of advantages such as вЂ“ No loss returns, higher lifting velocities, prediction of increased/decreased reservoir liquid rate affecting Motor winding temperature in ESPs, no settling of debris, post job Increased Liquid gain from well, decreased tubing friction pressure lossДЄbstract The key objective of multiple Coal Bed Methane (CBM) development operations is to determine cost effective methods to allow sustainable economic production and maximum reserves recovery. The modelling is done in Prosper and Cerberus, the results of which are validated with surface well test and Multiphase flow meter data recorded during the jobs. The paper describes new way of simulation for CT WBCO job in artificially flowing wells to predict decreased Liquid rate from reservoir, CT pressure & friction pressure losses. It also describes prediction for requirement of Surface Well Test spread support to assist Nitrogen assisted WBCO. ДЄbstract This paper describes simulation solution for CT(Coil Tubing) based WBCO in flowing ESP/Jet Pump wells for scale/polymer debris deposition removal prior to any treatment in well, such as вЂ“ Formation stimulation, ESP treatment, etc. The decreased reservoir liquid rate should be enough to cool down. Prediction of decreased liquid rate of well is required from prosper due to the following reasons:.

Prosper gives the new VLP (Vertical performanceД¬urve) when fluid flows from CT annulus up to the well head.re, lesser is the liquid rate produced Of curve shifts upward due to increase in friction losses. When Coil Tubing is lowered inside tubin. This data is exported from prosper at specific ESP frequencyДЄt which CT WBCO job is planned. Pressure data is functi.on of pump wear factor. Prosper modelling is to get pump discharge pressure data of the ESP. Objective of Prosper modelling in support to Cerberus for CT simulation Flow diagram giving ESP well challenges is mentioned in Figure-1.
