Abstract

For the past years, mud engineers had been running the gravel packing completion with two types of drilling fluid which are oil based drilling fluid while on the top part of the well and then switching to water based reservoir drilling fluid (RDF) when they reach the target zone. Even though it is a weU-known fact that oil based drilling fluid has many advantage, the engineers do not want to take the risk of doing something that is irregular. However, the usage of oil based RDF for gravel packing completion is increasing nowadays due to the increasing number of successful gravel packing completion project over the years. This brings an opportunity to look at the potential of a RDF which is based on Ester-based fluid produced from the Jatropha oil. Since Jatropha oil has untapped potential for being a RDF, I decided to see if it is applicable for gravel packing completion. There will be many parameters to look at but this project wilJ be focused on one of the important aspect in gravel packing completion which is the fonnation of filter cake. The filter cake that will be produced when the fluid meets the surface of a porous medium needs to be cleaned before the completion is considered complete. This is because the filter cake will disturb the porosity of the gravel packing and will cause drop in productivity. The main purpose of this project will be to produce the filter cake by running the Jatropha Esterbased fluid through a dynamic filter press machine. After that, a cleanup fluid (acid or surfactant) will be used to clean it and see if it is possible to destroy the filter cake. This parameter is very important because if the filter cake that is produced by the Jatropha Ester-based fluid is too thick and cannot be cleaned, then its potential for gravel packing application would be lessen.
