Summary: | During petroleum production, organic solid deposition will accumulate in the wellbore
and along the tubing. Therefore, production will be reduced due to blockage of production path
by organic solid deposition. To solve blockage of production path, high temperature chemical
will be injected into wellbore to treat organic solid deposition. As surrounding temperature is
lower, heat will be transferred from wellbore to surrounding. Hence, prediction of temperature
profile of injected chemical is needed so that suitable amount and reliable thermophysical
properties of chemical can be predicted. The objective of this project is to examine temperature
drop of injected chemical.
Microsoft Excel® 2007 together with Microsoft Visual Basic for Application (VBA) is
used to predict temperature profile of injected chemical. Model developed by Hasan and Kabir
will be utilized in this computer program. This project is divided into 2 parts. First part of project
will predict heat transfer and temperature profile of injected chemical. Second part of project will
examine sensitivity parameters of injected chemical.
In this project, there are several assumptions made to simplify the program created.
Simulation of temperature profile of injected chemical is shown in graph. Sensitivity parameters
are identified so that sensitivity analysis can be conducted. Sensitivity parameters identified are
injection rate, injection temperature and fluid density. The result of computer program implies
that it is plausible to predict temperature profile of injected chemical based on computer program
created. Computer program can be used on other type of injection fluid like water. Optimal
chemical condition for organic solid deposition treatment will be high injection rate, high fluid
density and suitable injection temperature. |
