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.

GN Solids Control is very professional at drilling mud system, then a client tell us a very simillar application: mud recycling for diamond drilling.  The size of cuttings is the main difference with diamond drilling and oil drilling.
In diamond drilling, the cutting size will generally be less than 10 micron. And it is needed to remove 100% of solids otherwise the drilling will run in to major dramas, in a short period of time.

Centrifugal separation is one main and effective separation way, while the mixtures can distinguish by gravity, which means with the same volume, the weight is different. In solids control system, there are two way to separate the drill cuttings from the drilling mud, screening and centrifugation.
As we all know the screening machine is the shale shaker, and they separate the drilling cuttings by volume, the bigger one left and the smaller be stored to next phase.

There are kinds of centrifugal equipments in mud system: Centrifugal pumps, hydrocycolone separator (desander and desilter), and decanter centrifuge.
The centrifugal pump is used to pump the drilling mud, and make the hydrocyclones work. While the other ones is the separation equipments.

Centrifugal Pump

SB series centrifugal pump is the ideal equipment to provide impetus for Desander 、Desilter and Jet Mud Mixer. It can also be used as Charge Pump auxiliary perfusion for mud pump and Trip Pump for drilling well head. centrifugal pump is also called centrifugal pump.We considered completely the set equipment can work in excellent condition in the process of designing parameters).Most parts can be exchanged , with convenient operation and maintenance、less seal leakage、reliability、long life and other advantages.

Vacuum degasser and poor boy degasser is both are degasser in oilfield, there are some differences some maybe confused.

How do the two degasser works and the difference

The vacuum degasser suck the drilling mud and separated mud and gas by vacuum pump.

Our vacuum degasser operates on a “thin strata” principle. The drill mud enters the tank and forces it to flow and distributed to a layer of internal baffle plates engineered to allow the liquid inside the vacuum degasser to flow as thin film and is exposed to the vacuum within the vessel. This layer of mud allows the gas to escape or break out of the mud . The vacuum pump releases the gas and discharge it to the disposal line. Mud exits the vessel under the action of the venturi and is returned to the mud system.

The poor boy worked by the physical characters.

The GN MUD/GAS SEPARATOR (poor boy degasser) consists of a cylindrical pressure vessel in a fixed vertical position. Inside is a series of specially angled baffle plates, stepped from the top to the bottom. When contaminated mud is routed into the separator, it flows downward successively over each plate. During this process, the heads of entrained gases “break out.” The released gas is then carried by the vent lines to a remote location where it can be safely flared. Continue reading →

Following is some recommendations for USA and Japan Centrifugal pump manufacturers.

• NOV Mission Centrifugal Pumps American Manufacturer

The National Oilwell Varco Mission centrifugal pump line has proven to be the best centrifugal design for handling abrasive mud. This pump line offers a broad selection of innovative features for a variety of routine, demanding, abrasive and corrosive applications. These pumps are designed for a wide range of flow rates, from a few gallons per minute to thousands of gallons per minute.

During the 1950’s the Mission® 1780 type “W” pumps were introduced to replace duplex pumps while creating the first low pressure mud system. The use of a high quality, concentric type centrifugal pump allowed abrasive fluids to be mixed and transferred while reducing initial and maintenance costs for the drilling industry. The low-pressure mud system with Mission 1780 Type “W” centrifugal pumps became the industry standard.

As well depths increased, so did the need for heavier mud weights. When the mud weight began exceeding 14 ppg, the need for a pump that could withstand greater horsepower loads arose. During the 1970’s, Mission organized a design

team that engineered the Mission Magnum. The Magnum was designed to have the same footprint, flange locations, and drive shaft diameter as the 1780 “W”. This allowed a 1780 to be replaced by a Magnum without any skid modifications. The Magnums were engineered with a 2 1/2″ shaft (3″ between the bearings), double row bearings with an engineered life of over 2 years at 200 HP, larger impellers and heavier frames. The Magnum allowed drilling contractors to upgrade their centrifugal pumps and mix heavier fluids.

National Oilwell Varco is dedicated to continual improvement of our product line and offering innovative solutions to service our customers for centrifugal pump.

Solid control system, also referring as mud system, is used to separate the solids or gas from the drilling mud. There are several centrifugal mud separators such as hydro-cyclone separators (desander and desilter) and decanter centrifuge, and mud gas separator, which separate drilling mud and gas.

Hydrocyclone Separator

Hydrocyclone separator is always referring as desander and desitler, used after shale shaker in the solids control system. Usually the cone diameter is more than 6″is called Desander, and used as the second-control equipment in drilling operation. the cone diameter is less than 6″is called Desilter, and used as the third-control equipment in drilling operation. We commonly used 5 “and 4” cone to separate solid-phase particle size 15-47μm in the drilling fluid.

Decanter Centrifuge

Decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system. Continue reading →

Once a client asked a very interesting question. If we add Solids control equipment system ( Shale shaker,mud cleaner & vacuum degaser ) to the centrifugal decanter separator what will be the advantages ,or we can utilize only the decanter?
Briefly answer this question: Drilling mud with drilling cutting is very complicated. So we need a system to deal with different solids.
The equipments before decanter is used to separate the solids bigger than 7μm，maybe you can only use decanter, but I should say it is a precision instrument, and it is tender. A system is needed to keep each equipment work in his own role, and prolong each one’s life.

The Separation Size of Every Phase of Solids Control Equipment:

Mud agitator is one important part of mud system, since GN Solids Control supply solids control equipments to Jidong Oilfield, there are 16 mud sotorage tanks, and each tank is used with 2 mud tank agitators. As we have introduced the mud tank agitator, here comes a more interesting question: how to size mud agitator.
I have give some Purchase Tips:

Please contact GN Solids Control representative with your tank dimensions and maximum mud weights for the correct agitator model, horsepower, impeller (size, type and quantity), and shaft length to meet your requirements.

• Mud Tank Dimensions

Mud tank dimension is used to confirm the length of the shaft and the type of the impellers.

• Motors

Which brand do you prefer, do you need explosion prevent motors.

• Gear box

This is the key part of tank agitator. Inch-bound is always needed. How to matching with the motor, and which rotate ratio is you really need.(Usually 60 or 72r/min)
P.S. : Contact GN Solids Control to get more professional advice.
