GN Sales team and one set of GNLW363BG Decanter Centrifuge hadattend Nigeria Oil Show in ICC Center in Abuja, Capital of Nigeria last week
and now GN Sales team was back from Africa and the above mentioned decanter
centrifuge was left there, sold to a customer whose main business is oil and
gas drilling waste management.

Although the crude oil price has dropped to
a historically low place, and as a country whose 70% income comes from oil,
Nigeria’s currency Naira’s value is lower than before, this Oil Show held in
Abuja still attracted lots of visitors from domestic and outside Nigeria. Abuja’s
ICC Center is located in the center city, at the first day of Oil Show, the
country’s most important political and economical leaders had attended the
Show.

Many local companies and companies from
abroad who have branch companies attended this show, comparing with their fancy
stands well decorated, GN’s stand was a bit plain. But GN was the only Chinese
company who brought with it a real product, a Decanter Centrifuge GNLW363BG. Its
shining bowl made of SS2205 attracted many visitors’ eyeballs. Many waste
management service providers showed their interest in GN’s standard waste
management system combined with GNCD930 Vertical cuttings dryer and GNLW363BG
Decanter centrifuge.

After a long holiday, which is the longestholiday in China, GN is back to work with full energy. Spring festival is mostimportant festival for every Chinese. After spring festival, according toChinese calendar, the new year starts. GN Solids Control is having a great start full of new orders.

Just before the holiday, GN has dispatched
20 sets of centrifuges to loading port, these centrifuges will arrive to
different countries in Middle East and Africa. In order to finish this order in
time, GN Producing department has been working around clock for at least 50
days.

Among all the equipments used for oil and gas solids control and waste
management, Decanter Centrifuge could better show a manufacturer’s
capability for producing. Each year, GN produce around 150 sets centrifuges,
and 70% of those are exported.

What Centrifuges does GN produce?

1.      High speed Decanter Centrifuge GNLW363C
series decanter centrifuge. This is 14 inch bowl decanter centrifuge,
and very popular size and design. For the same model, GN has highest
configuration and economic configuration available. The highest configuration
is suitable for waste management use and also regarded perfect as dewatering
centrifuge. The economic configuration is suitable for separating the fine
particles for solids control system. For each configuration, there are fixed
speed and VFD controlled available.

2.    Middle
Speed Decanter Centrifuge GNLW452, with a 18 inch diameter bowl. In some cases,
it is regarded as big bowl centrifuge. it is perfect in practice for recovery
the barite in solids control system. It has only one motor, and a middle speed
of 1800RPM.

3.      Big
Bowl Decanter Centrifuge GNLW553VFD Centrifuge, with 22 inch diameter bowl, and
71 inch long. It is a bigger sized GNLW363C decanter centrifuge.

4.      Baby
Centrifuge, GNLW223, the bowl diameter is only 9 inch, it is commonly used for
diamond drilling or some mining projects.

Among those above mentioned decanter
centrifuges, GNLW363CG-VFD is the best seller. And it is always used for
drilling waste management systems together with other equipments for further
treating the drilling cuttings from a solids control system. For WBM systems,
they always use high-G dryer shaker, and for OBM
and SBM, they always use vertical cuttings dryer. Both
mentioned extra equipments are available by GN Solids Control.

The tank design is very important to keepsure all design reaches requirement and convenient for operators. The mud tank need consider its usable muddepending on drilling conditions and need consider its active circulation todrilling hole. The mud tank capacity will be affect by drilling depth also .Usable
mud is defined as the mud volume which can be pumped before suction is
lost. For example, a typical 20,000 f t
well will normally require a minimum active system tank volume of 1000 bbl.

 

The active surface system will be divided
into two parts, solids removal and addition suction. All solids removal
equipment and degassing equipment in the solids removal part the addition suction
part is designed to make fresh mud to the circulating system and provide
sufficient residence time for proper mixing to occur before being delivered to downhole. A slug tank is usually available to pump
small “pills “such as LCM or barite slugs for tripping. Each part must be
further divided into enough compartments to efficiently carry out its designed
function and circulation application.

The quantity of compartments required will depend
on the amount and type of solids removal equipment like shale shaker, desander, desilter, decanter
centrifuge and vacuum degasses system size and circulation mud flow each
compartment must have enough surface area to allow entrained air to break out
of the drilling mud. A rule of thumb for
the minimum surface area is calculated by: Area (squarest) = Maximum
Circulating Rate (GPM)/40To maximize solids suspension and usable volume, round
type tank with conical bottom is the best option for a tank, square or
rectangular shape with V bottom is the second option for mud tank, Square or
rectangular shape with a flat bottom is the last option but easier for
manufacture. The ideal tank depth is same with the tank width or diameter of
the tank. This design provides good pump suction head and is best for complete
stirring.

GN builds many different type of tank with
different design; please contact us for more designs.

Comparably, a 3000bbl solids control system is not a small size one, it could be used for Chinese model oil and gas rig ZJ70, which means, the well depth could reach 7000 meters. Mostly, one 3000bbl solids control system is combined by 7 mud tanks, with a total storage capacity of 3000bbl.

Among the 7 tanks, there are trip tank, treating tank for shale shakers and mud cleaner ( also vacuum degasser), middle speed decanter centrifuge and high speed decanter centrifuge. the above mentioned is treating steps for the system. After that, it is mixing systems, which is mixing tank. On the mixing step, in the mixing tank, new chemicals are added into the drilling mud.

In standard design of GN 3000bbl solids control system, a mixing tank is designed of around 450bbl storage capacity. For this 450bbl mixing tank, there are below equipments needed:

1, mud agitators, GNJBQ150D-D, 3 ea. Mud agitators here are playing 2 roles, one is to keep the  mud from settling, the other is to help mixing work.

2. mud guns, GNNJQ80-3G, 3 ea. In a solids control system, mud gun pipeline reaches every tank, so mud gun is used not only to help agitators to stir the drilling mud at the corner, but also to transfer the drilling mud from one tank to another.

3. mixing hoppers, GNSLS45, 2 ea. Of course, in mixing tank, there must be mixing hoppers. The 2 mixing hoppers are paralleled to be installed, it means, either centrifugal pump could feed either mixing hopper by means of open/shut the valves.

4, centrifugal pumps for feeding the mixing hoppers, GNSB8*6-12J centrifugal pumps for feeding the hopper, as mentioned, they are paralleled installed for the hoppers.

There are two ways for positioning the mixing hoppers and centrifugal pumps depending on the customers’ requests. One way is to install hoppers on top of tank, while install the centrifugal pumps on tank skid, or to install both hoppers and centrifugal pumps on tank skid. Each choice has its own advantage and disadvantage.
