API RP 13C is the latest labeling procedure for shaker screens. Internationally, API RP 13C is ISO 13501.Now the API Screen Numbers are determined by the D100 separation (Microns).

Introduction of API RP 13C

The new procedure API RP 13C is a revision of the previous API RP 13E, which was based on optical measurements of the screen opening using a microscope and computer analysis. Under API RP 13E, screen designations were based on individual manufacturer test methods which produced inconsistent labeling. So it has many different criterion, and when we choose the shaker screen for the shakers, we are easy to get in trouble, even now with the API RP13C, we must convert the old one to the new label, then we can choose the right screen.

How They Test

The API RP 13C test contain two parts: cut point and conductance. It is a current criterion. Used all over the world.The tests describe a screen without predicting its performance.

The cut point test is based on a time-proven testing method used by ASTM to classify particles by size.

The D100 separation is used for assigning screen designations. D100 means that
100 percent of the particles larger than the test screen will be retained, and all finer particles will pass through.

Flow line divider is also one important part of drilling mud system. And it can be used with solids control system o f GN Solids Control. However, it used not very popular in China.

Main Introduction of Flow Line Divider

Drilling mud flow line divider is used to optimize the solids removal capabilities of shale shakers. In this article, we introduce famous brand flow line divider like Derrick Flo-Divider, and Brandt Dual Cartridge Scalper, Baroid’s Unique SupaVac™ SV400 Cuttings Collection and Pumping System.
By pooling and dividing the drill fluid upstream from the shale shakers, the Flo-Divider ensures that each shaker receives an equal flow of drilling mud and an equal distribution of drilled solids.

Brand flow line divider

Derrick Flo Divider have 4 types of model by the divided way: 3-way, 4-way, 5-way, and 6-way, it fits easily onto most rigs, and is applicable for all derrick shakers.
Brandt flo line divider: The Brandt product line of NU-TEC Gumbo Removal Equipment is the first step in effective solids removal when sticky clays and gumbo are drilled. The Gumbo Box™, in conjunction with either the Gumbo Chain™ or Scalper™,  can virtually eliminate plugged flow-lines by removing the gumbo before it reaches the shale shakers.
The SupaVac™ SV400 unit is a compact, air-operated, vacuum recovery and pressure discharge pump. This system is designed to operate in hazardous locations, safely collecting and pumping materials such as drill cuttings, tank bottoms, heavy crude sludge and sand slurries.

Centrifuagal pump is widely used, in all the industry and agriculture even in the life. In the oil well drilling, or just water well drilling, HDD, environment protection, they are core parts though there are a lot of equipments. They charge the transportation for the separation work.
What they really do is pump the mixture of solids and slurry or drilling fluids from one stage of separation to another stage. As shown in the picture.

In the jet mixing system, they pump the fluids to go through the venture hopper, then the chemical things or other materials can be added. and then go back to the tank.

Components of Centrifugal Pump
The components of this kind of centrifugal pump, for separation work, is a little different from the others, though the structure is still the same.

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 “Geological Exploration Before Drilling”

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.
