Abstract
Lost Circulation Materials (LCM) are specially designed not to damage the penetrating formation during handling of loss
circulation problems and are very effective for drilling operations worldwide. Optimization of LCM composition may stop loss
circulation effectively and protect the production zone from the invasion of mud filtrate. The concentration of lost circulation
materials (LCM) is a key parameter to determine the effectiveness of LCM. In this study, laboratory equipment such as the
Hamilton beech mixer, Fann VG meter and API filter press are used to evaluate the effectiveness of various LCMs in dealing
with loss circulation. In this research, coconut fibre, banana tree skin, and bagasse are used as LCM in various
concentrations. The mud losses were simulated using an 80 mesh shaker. The quality of the muddy rheological properties was
the basic parameters to be evaluated. The test was carried out at 80oF and 200oF. The experimental results show that bagasse
has the best performance both at 80oF and 200oF as LCM compared withcoconut fibres and banana trunk. The lost circulation
of mud filtrate at 80oF and 200oF due to the addition of 2 gram bagasse is 34 ml and 40 ml, respectively.

I. INTRODUCTION
Loss Circulation is a problem that often occurs
in drilling operations, namely the migration of
drilling fluid into the formation. Drilling by
penetrating formations that have large
permeability, large fractures and areas with low
pressure, resulting in a partial and even partial loss
of formation fluid, loss circulation is a very
difficult challenge, because it can cause cost
overruns and time to handle it (Adam, 1985). As
explained earlier, loss circulation is a problem that
is troublesome and requires a large amount of
money in handling it in this industry. The classic
problem in drilling penetrates large cracks, low
pressure and large permeability is not only difficult
but also expensive and risky. Migration / invasion
occurs in cavernous, hollow (vugular) formations,
unconsolidated fractures or rocks. In dynamic
conditions, the fluid migration process increases,
this condition is due to the large pressure difference
between formation pressure and hydrostatic
pressure, decreasing the viscosity value due to the
effect of voltage and thinning of the mud cake due
to trip in - trip out and circulation. There are many
studies to overcome the problem of loss circulation.
In research, several materials such as bagasse,
cocout fibres, and banana trunk were used as LCM.
The effect of each material on mud slurry rheology

was tested.
II. LITERATURE REVIEW
Until now, the drilling industry has developed
Underbalanced Drilling (UBD) technology, this
technique is used because it has the advantage of
reducing formation damage and minimizing loss
circulation problems, but in this case UBD
techniques require special equipment and trained
crew, so that costs are needed. big and always
updated technology (Perez-Tellez, 2002). Drilling
mud is one of the main components that determine
the smoothness and success of a drilling operation.
The sludge system used in a drilling operation must
be in accordance with the conditions of formation
and lithology that must be penetrated (Adam,
1985). There are two main problems that occur in
loss circulation, namely invasion / migration and
large fractures. Loss circulation can be classified
into three parts, namely seepage loss (1-10 bbl / hr,
partial loss (10-500 bbl / hr), total / complete loss
(over 500 bbl / hr) (Rabia, 1985). Coconut fibres as
biosorbents to remove heavy metals from the
waters are quite high because coconut fibers
contain lignin (35% - 45%) and cellulose (23% -
43% (Carrijo, 2002). Fiber from banana stems
comes from banana plants that have been cut down
for the fruit is taken and is an agricultural waste
that has not been widely used. Banana stem fiber is
one source of fiber that has a source of fiber that
has a high cellulose content. Banana stem has a
specific weight of 0.29 gr / cm3 and fiber length
4.2-5.0, 46 mm and lignim content of 33.51%,
(Husin, 2007). Baggasse bagasse mostly contains
ligno-cellulose. The fiber length is between 1.7 to 2
mm with a diameter of about 20 m, so that the
bagasse can meet the requirements for being
artificial boards or for other purposes. Bagasse
contains 48 - 52% water, average sugar 3.3% and
average fiber 47.7%. Bagasse fiber is insoluble in
water and consists mainly of cellulose, pentosan
and lignin [3].
III. METHOD
The laboratory study used a mud which was
based on fresh water (Water Based Mud). The
composition of the drill mud as well as the
properties of mud is very influential on drilling.
Casing planning, drilling rate and completion are
influenced by the drill mud which is used at that
time. For example in areas with soft rocks,
controlling the nature of mud is very necessary. But
in areas with hard rock these properties are not too
critical so that water can sometimes be used. It can
be said that the geological properties of an area also
determine the type of mud to be used. Various
additives are intentionally added to the mud to
produce certain properties needed to carry out their
functions. Drill mud must be thixotropic which is
runny (liquid) when stirred or pumped and if the
mixture / pump stops the mud will form gelatinous
properties (gel). This property is required if the
circulation is stopped due to pump damage, for
example, the cuttings remain propped up not to the
bottom of the well and cause the pipe to be pinched
or re-formed (regrinding) which will become a clot
in the bit (bit balling). In the laboratory testing,
rheology determination was obtained and observed
in reading the equipment used during the study,
including Mud Balance, Fann VG Meter, API Filter
Press, Hamilton Mixer, an 80 mesh filter and other
supporting equipment. A mud which composed
water volume of 341.22 ml, Bentonite of 22.5
grams and Caustic Soda of 0.5 gram was made.
Then experiments were conducted to determine the
rheological properties as given in Table 1. The
research referred to API 13B-1 [2].

IV. RESULTS AND DISCUSSION
Continuous testing of fresh water-based mud
with the addition of the number of additives was
testing. The additives used were coconut fibers,
baggasse pulp, and banana tree skin with each
composition (gram) 0 gram, 0.5 gram, 1 gram, 1.5
gram, and 2 gram at a room temperature of 80oF
and mesh size of 80.
Tables 2 and 3 show lost circulation by adding
2 gram LCM additive at 80oF and 200
oF. The tables
show that have a minimum value of Water / Fluid
loss on temperatures of 80oF and 200
oF. This
means that bagasse is the most effective LCM
compared with coconut fibres and banana trunk.
The complete experimental results are shown in
Figures 1 and 2.
Figures 1 and 2 indicate that the addition of
additives such as coconut fibers, bagasse and
banana tree peels into basic mud is able reduce the
mud filtrate. In this case, coconut fibers, bagasse
and banana tree peels have a function as lost
circulation materials (LCM) at temperature 80oF

and 200oF. Other information obtained from the
figures is bagasse has the highest performance
dealing with lost circulation compared with
coconut fibers and banana tree peels both at
temperature at 80oF and at 200
oF. Figures 1 and 2
indicated that coconut fibres are more effective to
handle lost circulation than banana trunk peels at at
80oF but they are less effective at 200
oF.

IV. CONCLUSIONS
During this study, the performance of coconut
fibers, bagasse and banana tree peel was tested as
lost ciculation materials (LCM) in drilling water
based on freshwater. The difference in
concentration / composition of coconut fibers,
bagasse and banana tree peel uses 80 mesh pore
sandy media. The observations have been analyzed
so that conclusions can be drawn as follows:
1. Coconut fibres, bagasse, and banana trunk have
a function as lost circulation method, since they
are able to reduce the lost circulation volume of
freshwater based mud.
2. Baggasse is the best additive compared with
coconut fibres and banana trunk, since it
resulted in lowest lost circulation volumes for
various additive concentrations and
temperatures of 80oF and 200
oF.
3. Increasing the amount of concentration/
composition of additives (coconut fibers,
bagasse and banana trunk) from 0.5 gram to 2
grams both at temperature of 80oF and 200
oF
will further reduce the volume of lost
circulation. The smallest mud filtrate loss
obtained by adding 2 gram bagasse into mud
slurry which is 34 ml and 40ml at 80oF and
200oF, respectively.
