Up to now, GN Solids Control have mature solids control equipment models. This can meet most of the requirement from end users, but not all. Some special requirement from customers, we have to take more time to do some necessary works. Eg. Shale shaker. GN Solids Control have 3 basic model shale shaker, GNZS752 series shaker, GNZS703 series shaker and GNZS594 series shaker. The treating capacity is 200gpm, 500gpm and 600gpm separately.  For workover rig or small geothermal rig, the separate shale shaker is enough to treat the returned drilling mud from rig, but for large oil drilling rig, 2 or 3 sets of shale shaker generally required.

Dual Connection Shale Shaker

GN just got Purchase order from Egypt Drilling Company. They require one set Dual connection shale shaker. The dual connection shale shaker should come with distributor to separate the drilling mud evenly from the well. GN Solids Control connect two sets GNZS703 series shale shaker with same big base to connect. You can see more details from the pictures.

GN 1000gpm Dual connection shale shaker technical specs:

Shaker model: GNZS703E-HB

Shaker qty:  2 sets

Total treating capacity: 1000gpm

GNZS703 shale shaker produced by GN solids control has been widely used in oil & gas drilling. GNZS853 shale shaker is normally used for drilling cuttings treatment.

Below is the photo taken in South America oilfield drilling site. They use GN shale shaker to separate the large solids from the drilling fluids and get clean mud for reuse. Also they user GN shale shaker as a underflow shaker to help the performance of desander cone & desilter cone.

To know how to operate GN shale shaker is much more important, also the maintenance. Only if you operate and maintain it according to the manual, you will use it same with some famous brand  shale shakers.

1 Angle adjustment

The angle can be adjusted both under running and off condition.When delivered ,the deck is horizontal(0°) While operating with the same shaker screen, according to the worksite mud property, and feeding capacity ,by adjusting the deck angle in order to improve the treatment result .When the drilling mud run off, enlarge the deck angle to solve the problem. Angle adjustment range -1°~+5°rated angle 0°~3°

2 Pool configuration

A better pool configuration can maximize the screen area and such achieve better result. It is hard to set the deck angle at one time ,it needs the operation personnel adjusting several times according to the flow of the mud .The best pool configuration is when the mud covers the first and second shaker screen.

3 Screen tention

Screw conveyors, sometimes called augers or auger conveyor, are used as an efficient way to move a wide variety of materials. The auger is used to move material along a path using a helical screw. The process of drilling with a helical bit involves aspects of both: the creation of the hole with the tip of the bit is drilling, while moving the waste material out of the hole along the helical path is augering. Not all drilling involves augering (oil field drilling uses a pump to move the material). Screw conveyors in oilfield are often used horizontally or at a slight incline as an efficient way to move drilling fluids with drill cuttings.

Auger screw for oilfiled

Auger screw for oilfiled

Main components of Auger screw:

Motor, control panel, Screw( including blade and shaft),Conveyor housing, Supporting feet and saddles, Feed and discharge spouts, Cover, Through end, etc.

Screw consists of a several of blades of helix shape welded to a pipe or shaft. It moves the material. The following specs should be calculated carefully for proper use: Flight outside diameter, type of blades, spacing between the blades, thickness of the external diameter and interior shaft and rotation direction.

The drilling fluids with the cuttings from the well are discharged to a rig shale shaker where the cuttings are separated from the drilling fluid. The separation step does not completely remove drilling fluid from the cuttings, some drilling fluid and additives remain on the drill cuttings.

Then such drilling cuttings with drilling fluids will be dropped into a GN drilling waste system, through physical way to separate the usable drilling fluids with unusable drilling cuttings. For example, hi-G shale shaker to separate larger drilling cuttings, then verti-cutting dryer to separate drilling cuttings with oil less than 5%.The usable drilling fluids are treated by decanter centrifuge, then clean drilling fluids and water will back to rig again.

The cuttings separated by verti-cutting dryer with less than 5% oil can not be drain off directly, it may pollute the environment. We must use chemical way to continue the treatment.

Drilling cuttings treatment method:

Thermal desorption, re-injection, incineration and solidification.These methods have been applied in the site, they may have their own advantages and disadvantages.

Thermal desorption:

use of the patented Porcupine Processor to remove all water and oil, leaving a residual total petroleum hydrocarbon on cuttings of less than 1%.

Re-injection :

Workover is used to refer to any kind of oil well intervention involving invasive techniques, such as wireline, coiled tubing or snubbing. More specifically though, it will refer to the expensive process of pulling and replacing a completion.

workover parts

workover parts

Workover Rig is available for both onshore as well as offshore. Before any workover, the well must first be killed. Since workovers are long planned in advance, there would be much time to plan the well kill and so the reverse circulation would be common. The intense nature of this operation often requires no less than the capabilities of a drilling rig.

Workover parts may include the following parts basically:

Workover rig, Manifold, triplex mud pump, mud system, BOP, Top drives, Blow out preventers.

Workover mud system:

GN solids control produced workover mud system for 250HP, 350HP, 450HP, 550HP, 650HP,750HP workover rigs. They have been applied in more than 60 countries in the world. Some clients may get the mud system from rig package supplier. But a much sane choice is to buy the mud system separately from solid scontrol Continue reading »

Main Introduction of Geological Exploration

Geological exploration is to discover resources of value from the earth, while you get some information from the earth’s surface. And it takes risks, you never know if it will work until you get the truth.An exploration geologist is a person who do this job.In addition to finding the resources needed, the core samples may also show where the easiest places to drill will be. This helps not only find the resources, but to harvest them in an efficient and cost-effective manner.

A Few Interesting Questions

1 Why do we need natural resources?
Then when you walk out, try to think about it, then you will find the answer, nearly everything around you is relative.
2 How do we find new resources?
The answer is it is a very hard work.

Geological Exploration Company

Rosneft puts much emphasis on volume and efficiency of prospecting and exploration work in order to replace hydrocarbon production with new commercial reserves and to ensure sustainable growth of production in the medium and long term. Continue reading »

Desander is a very important part when using machines to separate solids and liquids, and widely used in oilfield and hdd and mining projects. Here is the detailed information, the definition, and the desander’s use, especially in oilfield, then I will recommend the GN ZQJ series desander.

What is a desander

bentonite desander

hydrocylone bentonite desander

Desander is the second class and the third class solid control equipment to treat the drilling fluid. Usually the cone diameter is more than 6″is called desander, and used as the second-control equipment in drilling operation. We commonly used 8 “and 10” cones desander to separate solid-phase particle size 47-76μm in the drilling fluids
When referring the desander, hydrocyclones are very urgent to come to the stage. Hydrocyclones is also called cyclone separator.Hydrocyclones are drilling rig equipments with a set of hydrocyclones that separates sand and silt from the drilling fluid. Desander is installed after shakers and degasser but before desilter. It removes those abrassive solids from the drilling mud which cannot be removed by shakers. Continue reading »

Oil and natural gas corp. today declared the finding of three oil and gas this month, it has approved that they would invest Rs 3241 crore in developing Cluster-7 marginal fields in the western offshore.

ONGC said it discovered gas in a well drilled in East Godavari district in Andhra Pradesh. Oil and gas in a separate well in shallow waters off the Andhra coast.

Besides oil was discovered in Gujarat block, a company press statement.But ONGC did not give estimation of it.

To invest the discovered oil, the company board approved a capital expenditure of Rs 3241.03 in the first phase of development.

In the first phase, they plan to install four new fixed well platforms and drilling of 20 development wells from which the cumulative production of oil and gas for 16 years. And the production is expected to be 9.73 million tons and 4.52 billion cubic meters.

In their plan, the project is completed in 35 months later, and the first oil is expected in March,2010.

GN solids control, as an leader of the oil and gas associated industries, is very exciting to hear this, as the price of oil and gas is rising all the time, more exploitation is really needed.

As we all know, the urgent demand of oil and gas inspire the exploitation and drilling and also the solids control etc. In GN solids control, we only produce top quality products, and we really welcome the customers all over the world which needs solids control.
