Ball Clay
Our product How it works Benefits
d Ball clays are
mineralogically and
morphologically similar to many types of shale
d Hymod Prima consists
primarily of fine particle
size disordered kaolinite,
quartz, mica and some
swelling smectites
d Consistent reproduction of
effects of drill solids on
� Fluid loss
� Rheology
� Stability
d Our Hymod Prima is a
ball clay product that has
been used widely in
ceramic applications for
many years due to its
consistent quality
d It is widely used to
simulate drill cuttings in
laboratory mud
formulations
1µm
Bentonite
d ECCAgel, our bentonite is sourced from South Africa
d It is a non-treated (or natural) sodium bentonite
d API specification13A/ISO 13500 section 11 (OCMA grade)
Our product How it works
d Bentonite provides
viscosity and gelling characteristic to WBM
d Rheological properties: bentonite suspensions
develop a yield stress
and show strong shear
thinning behavior
d Viscosifier to suspend
weighting agent and
cuttings
d Filtrate reducer to
decrease fluid loss from
a wellbore fluid, forming
a thin tough filter cake
1µm
Benefits
Calcium Carbonate
Our products How it works Benefits
d Carbonates can be used
� As weighting agents for
reservoir drilling fluids
� As bridging agents
d Particle size range enables
� Bridging of fractures and
formation pores
� Building a filter cake at
the entrance of the
fracture to seal it up
d Prevent formation damage
d Control seepage and
circulation losses
d Easily removed by acids or
chelants
d Calcium carbonates from Marble, Limestone
and Chalk sources
d Dolomites (Ca/Mg CO3)
d Wide range of particle
size distributions
available worldwide
d Fully Acid soluble

Mica
Our product How it works Benefits
d Coarser grades are
effective to control losses, pumped as a pilltreatment to plug fractures
d Fine grades pass through
shaker screens, so they
can be used as a pre-treatment to control seepage losses
d Stop lost circulation
d Prevent fluid loss and
formation damage
d Mica consists of high
aspect ratio, flake-shaped particles
d Imerys has a range of
controlled particle size distribution products

Graphite
Our product How it works Benefits
d Reduce torque and dragin deviated wells
d Control lost circulation
d Strengthen wellbore by
the ‘stress-cage’ effect
d Imerys offers a large
range of natural flake graphite
d Our range includes a high degree of crystallinity,
which equates to near
theoretical true density,
high thermal and electric
conductivity
d Graphite particles bridge and block fractures
d Particles form a strong
plug, but with sufficient
flexibility to withstand
changes in wellbore
pressure
d Graphite is an efficient
lubricant between
drillstring and wellbore

Diatomite / Perlite
Our product How it works Benefits
d Diatomite and perlite are
a natural filter aidsthanks to their structure
d Combined with other
materials such as organic
fibers, they can be used
as a pill or "squeeze" treatment.
d Filtration of completion
fluids
� Crystal Clear fluids at low
cost
d Control of losses
� Rapid bridging and shut-
off of large loss zones
d Diatomite is a natural
silica mineral made from
skeletons of single celled
organism called diatoms
d Our diatomite is calcinedto remove impurities
d Perlite is volcanic glasswhich is expanded into
bubbles, then milled to a
powder of extremely low density
