Key words: simulation of cleanout program after a fracturing operation, multiphase flow, normalization of bottom hole condition.
The article focuses on verification process of cleanout program simulation after a fracturing operation and proppant extraction from an oil well with the help of gas-liquid flow “water + nitrogen” and using Coiled Tubing at Sutorminskoye field.The paper provides comparing of two modeling methods of proppant extraction. This methods bases on usage a standard computer program CoilCADE-WellboreSimulator (Schlumbeger) and the software system OLGA , which has not been used previously for such processes in explicit form. The implication of cleanout program simulation with help of multiphase flows have allowed to define that both programs show similar qualitative and quantitative results. This significantly extends the applicability of the software system OLGA for cleanout simulation in an oil well after fracturing operation with usage of Coiled Tubing.
