Weighting materials |
| |
-
API BARITE is used in
all drilling fluids for the purpose of increasing
density. Barite, which is predominantly barium
sulphate, has a specific gravity of 4.20 or
better and is chemically inert to drilling
fluid additives.
-
TP-CALCIUM CARBONATE(C,M,F)
can be supplied in a variety of grades to
provide bridging or weighting particles of
completion or workover fluids. It can be also
used as non-damaging loss circulation or bridging
material in oil muds to prevent differential
sticking or mud losses when drilling into
the reservoir. The material is acid soluble
so that good clean-up is obtained by acidization.

 |
Viscosifiers |
| |
-
API BENTONITE is used
to increase viscosity and reduce fluid loss
in water-base drilling fluids. It is a cost-effective
means of achieving viscosity, fluid loss control
and filter cake quality in freshwater and
seawater muds.
-
DK DRILL-A1 is a partially
hydrolysed polyacrylamide of high molecular
weight. DK Drill-A1 is used for increasing
viscosity in both freshwater and seawater
-
VISKOPOL is used mainly
for the make-up of viscous sweeps when drilling
with water in large diameter holes. VISKOPOL
is quick to mix and gives relativily high
viscosity at low concentrations and is therefore
ideally suited for formulating spud muds
-
XCD POLYMER solution may
be susceptible degradation, so a preservative
such as biocides is recommended. At mud PH
value above 10.0, XCD POLYMER becomes more
sensitive to soluble calcium and may be precipitated
out of solution, however, it can be added
to most waters regardless of salinity. XCD
POLYMER can also be used in lieu of bentonite
to produce a no-solids viscous fluid.
-
Additions of NEW VIS yield
shear thinning fluids. Viscosity is low at
bit shear rates to optimize penetration, and
is high at low annular shear rates to provide
maximum hole aging.
|
 |
Filtration control additives |
| |
-
CMC (LV, HV, EHV) is effective
as a filtration control agent, protective
colloid and viscosifier for low solid, water
base muds. CMC is stable at temperatures in
excess of 120oC (250oF). CMC is relatively
stable to bacterial fermentation. It is effective
in fluids containing up to approximately 50,000
mg/l sodium chloride. CMC is more effective
when concentration of calcium are less than
500 mg/l.
-
PACSEAL-LV can control
filtration of water base muds without severe
increase in the mud viscosity. PACSEAL-LV
is resistant to microogranisms. PACSEAL-LV
control the filtration rate freshwater and
saltwater muds
-
PACSEAL-R is added to
freshwater or saltwater muds to reduce the
filtration rate of the mud and improve filter
cake quality. The regular viscosity grade
is normally used in low-solids and low-weight
muds. The super-viscositygrate is recommended
for high solids muds to avoid excessive viscosity
build-up.

Lubricants |
| |
-
PK-LUB is recommended
for reducing torque and drag in any drilling
fluids. PK-LUB is compatible with both fresh
water and sea water muds and is equally effective
in weighting-non weighting materials or low
solids muds when used as recommended.
- LUB-LS is recommended for reducing torque
and drag. Improve lubricating qualities of water
based fluids. Free stuck pipe when added in
proper concentrations. At temperatures of up
to 150oC, LUB LS remain effective and stable.
-
MIL-LUB is recommended
for reducing torque and drag in any drilling
fluids. MIL-LUB is compatible with both fresh-water
and sea-water muds and shows no tendency toward
foaming, abnormal flow property changes, or
"greasing out" on weighting material
when used as recommended. MIL-LUB is most
efficent at a PH below 9.5, and performs best
at a PH of 9.0 or below. MIL-LUB will resist
hightemperature [ over 149oC (300oF)] degradation
and "greasing out" in the presence
of hardness, when PH is controlled in this
range
-
RADIAGREEN EBL is a readily
biodegradable and non toxic ester based lubricant,
developed to increase drilling rates in operations
using water based mud. Alow addition of Radiagreen
EBL significantly reduces torque and pipe
drag and minimizes bit balling. Radiagreen
EBL is a readily emulsifiable in any water
based mud (WBM). Its use does not affect rheology,
filtration behaviour nor any other mud property.
Radiagreen EBL is also effective in high density
formulations. An addition of 3% results in
a remarkably lower torque. The risk of stuck
pipes ist vastly reduced by adding Radiagreen
EBL, as it decreases the differential sticking
pressure. The addition of 2% eliminates all
sticking. At temperatures of up to 160oC,
Radiagreen EBL remains effective and stable.
|
 |
Shale control/Hole stability additive |
| |
-
PHPA can be added to water
based drilling muds on its own or in combination
with KCL, to inhibit shale bearing formations.
Due to PHPA’s encapsulating property, clay
and shale problems such as sloughing, swelling
and bit balling are effectively prevented.
PHPA reduced uncontrolled build up of colloidal
solids and thus ensures control of viscosity
at high penetration rate. This effect of PHPA
on viscosity, decreases in high salt concentration.
PHPA loses it’t effectiveness at higher calcium
and magnesium ion concentration. These bi-valent
cations should be kept to a minimum with Soda
ASH.

Loss circulation materials |
| |
-
MICA (C, M, F) is used
to prevent loss of circulation in thief zines.
Mica can also be used in oil-base muds. .
-
TP-NUTLOSS (C, M, F) is
used alone or in combination with other material
to combat loss of circulation. TP-Nutlost
can be added to the mud through the hopper,
or directly to the suction pit if sufficient
agitation is available. Treatment levels will
depend on the severity of the loss-of-circulation
problem. The shaker screeens will remove them
from the mud system.
-
MIL SEAL (C, M, F) is
added to combat a severe lost-circulation
problem. Pretreament of the mud is sometimes
done but not generally recommemded as screens
must be bypassed, faccilitating a buildup
of low-gravity solids. The fine ground product
can be added in low concentration of 5.7 to
14.3 kg/m3 (2.0 to 5.0 lb/bbl) to aid in sealing
microfissures. This product will pass through
maximum of 20-mesh screen.

| |
-

be added by sprinkling over the mud pits,
or where a hydrocarbon oil may be tolerated
as a suspension of 2.3 to 4.5 kg (5 to 10
lb) per 18.9 liter (5 gal) of oil. ALUMINUM
STEARATE is highly effective as a defoamer
at low concentration levels and has minimal
effect on mud rheology.
-
ANTI-FOAM controls froth
and foam in dispersed and non-dispersed aqueous
muds. ANTI-FOAM also controls the foaming
of polymeric fluids which are charectericzed
by high yield point to plastic viscosity ratios.
The high viscosity imparted by polymers can
open result in considerable foaming, which
ANTI-FOAM is effective in removing. ANTI-FOAM
remains effective after initial defoaming
and continues to suppress foam generation
over extended period of time. Rigorous agitation
appears to enhance the defoaming property
of ANTI-FOAM.

control aerobic bacteris such as a slime formers
and anaeribic bateria such as sulfate reducers

freshwater muds to reduce viscosity and gels
and to reduce the hardness level.
-
FERRO-CHROME LIGNOSULFONATE
(FCL) is used as a deflocculant and filtration
control agent at alkaline PH in water based
system, including fresh, salt and calcium-treated
water base muds. FCL provides excellent thermal
stability for the control of rheological and
filtration prorerties. FCL will also inhibit
the reactivity of clay solids when used in
proper concentration. FCL is commonly used
to prevent salt flocculation of bentonite
and to reduce the effects of high temperature
gellation in bentonite fluids.
|

MIL FREE is recommemded
for freeing differentially stuck pipe in water-base
muds when an unweighted spotting fluid can
be safely used.

fluid at the rig site.
