PROPERTIES AND UTILIZATION OF JATROPHA CURCAS OIL FOR FORMATION DAMAGE CONTROL

This report basically discusses the preliminary research done and basic understanding of
the chosen topic, which is Properties and Utilization of Jatropha Curcas Oil for
formation Damage Control. Jatropha seed is the seed from the jatropha trees. The seeds
from this tree will be used as a research product. Jatropha trees canbe easily plant at the
khalatulistiwa area. The trees are very easy to plant and its have very strong physical
properties. The oil from jatropha seeds can be produced by two ways: mechanical
pressing and chemical extraction. In general there two types of products from jatropha
oil: as cosmetic and biodiesel. For biodiesel, there are a lot of researches on producing
the biodiesel Then, this research basically is about to expand the used of thejatropha oil
as a part of drilling fluid in the oil and gas industry. The oil will be used as an oil base
mud for drilling. Nowadays the type of oil that used as an oil base mud in drilling is
diesel and palm oil and of course these two types of oil are very high demand in the
market. Formation damage is an undesirable operational that frequently happened during
drilling activities. The damage of the formation will reduce the permeability and the
porosity ofthe core to transfer the crude oil from wellbore to the well. The damage may
cause by several factors including chemical, physical, biological and thermal interactions
of formation and fluids, and deformation of formation under stress and fluid shear. For
the physical mechanism of formation damage clay swelling, fines migration, solid
invasion and geochemical transformation will be the major factor of formation damage.
For the chemical part the type ofmud will bea major cause ofthis phenomena. Then, it is
important for the mud engineer to determine the right composition ofthe mud that used
as a drilling fluid. The objective of the project is to determine the properties of the
jatropha curcas fruit in order to apply it to substitute the surfactant that used nowadays in
the reservoir by determine the rheology of the mud using the drilling lab equipment such
as mud balance to determine the density of the mud and the viscometer to determine the
other important parameter like Yield Point and Plastic Viscosity. The standard for all this
parameter will refer to the API standard. The research will also investigate the reduction
of formation damage by this mud using FDS-800-10000 equipment at UTP drilling lab. The parameter that involve in this activities will be the change of the permeability and
porosity ofthe core. The condition oftemperature and the pressure will be set equally as
in the reservoir before the experiment being applied. The hypothesis for this research is
theoil can beused aspart ofthe oilbase mud in during drilling activities.
