Noted of solids control system

On the basis of group together the advantage of solid control cycle system, domestic and international alike, the solid control cycle system is a the system product which is designed by grouping the practical demand together of the well drilling craft.

Solids Control System 7

It practice by five level treating sections: shale shaker, vacuum degasser, desander, desilter and centrifuge. It can process, then storage and mix of drilling fluid in the tank below the solids control machines, remove the harmful solid cutting, maintain the level of purified of the drilling fluid. Drilling fluid that require in the special situation during the cycle such as fluid weight added, shear and issue removal, and can increase the efficiency and safety of well drilling function effectively. It is convenient to transport by the road and railway, and it can be moved to the well site at a minimum distance.

The corresponsive match of the solid control equipment is essential, the one to five level of the process should be correspond each other, and the interval of separation size should be appropriate and have a certain overlap, and the smaller particles which are not disposed by the upper can be disposed in the next level.

 

Purification process cycle of drilling fluid

 

The mud which is withdrew out from the wellhead then it well be transported to shale shaker  or enter into the mud tank below after disposing by shale shaker. The mud which overflowed from the mud tank (if the gas exist, it can start the vacuum degasser, and inhale mud from the degassing warehouse, and enter into the desanding after degassing). The mud will enter into desilter  after be disposed by desander. The mud disposed by desilter enter into drilling fluid centrifugal through the mud tank, the mud disposed by centrifugal enter into the vault and through the mud tank, and the well drilling pumps pump the drilling mud into well hole repeatedly for using circularly.

It contents the normal cycle and stable status of the mud in the drilling process. Under the premise of safety, environmental protection, efficiency to ensure the task of well drilling.

Breaking News – Halliburton in Talks to Buy Baker Hughes

Merger talks between Halliburton and Baker Hughes stalled yesterday with the companies still haggling over price and divestiture concerns, people with knowledge of the matter said.

Halliburton could make an unsolicited tender offer for Baker Hughes instead, and nominate a slate of directors to the target’s board, three of the people said, asking not to be identified discussing private information. Alternatively, the companies may still be able to revive the negotiations, one person said.

Baker Hughes fell about 3% after the close of regular trading, to $58.10 a share as of 5:26 p.m. in New York. Halliburton fell to $54.53 after closing at $55.08 apiece.

Baker Hughes, based in Houston, said yesterday that companies are in talks. Ahead of the disclosure, a person with knowledge of the matter had said a deal could come as soon as Monday.

Since then, the two sides have become stuck on disagreements about the deal’s price and the billions of dollars in assets that would have to be sold for the deal to pass antitrust scrutiny, one of the people said. Combining the world’s second- and third-largest oilfield service providers will draw scrutiny from antitrust regulators.

The companies may have to sell $7.5 billion to $10 billion in assets to address regulator concerns, two people said. They generated a combined $55.5 billion of sales in the twelve months through September, data compiled by news outlet Bloomberg show.

If the deal went ahead it would create a company with 140,000 employees.

Mining Industry Slim Hole Drilling Application in Oil Exploration

Nowadays, the oil drilling company more and more find the advantages of application of slim hole drilling in the oil exploration. This type slim hole drilling technology is coming from the mining industry. From the name, we could see the slim hole drilling actually represents the small diameter coring drilling.

The slim hole drilling not only provide the cores for the drilling, it also reduce the drilling cost by nearly 30% comparing with the conventional drilling, especially for the environmental sensitive and remote area drilling projects. For remote location, the smaller core hole rig package also greatly reduces the logistics and transportation expenses.

A well with diameter that is smaller than 8 1/2 would be the most accepted criterion for the slim hole drilling. Reducing the borehole diameter can significantly cut the drilling cost as less mud and casing would be required. And the slimhole rig weighs sometimes only about one fifth of the conventional rig. In additional, the saving of slim hole drilling will also come from many sources, such as less site preparation, easier equipment mobilization, less cuttings to dispose, reduction in the amount of cosumables and smaller equipment. Besides the cost saving, there are advantages of slim hole drilling that makes the operation particularly suitable for sites demanding on a low impact to the environment.

Although, the slim hole drilling is actually increasing clearly, the concern on the safety is inhibiting the rapid spread of slim hole drilling. It is available for an operator to assemble the slim hole drilling equipment within 3 to 6 months with no previous experience. But it will not be easier to achieve for the deeper hole and offshore drilling. The application of slim hole drilling still depends on how successful this technique would be developed in the next few years.

No matter for the coring drilling and slim hole drilling for oil exploration, the rig may request a drilling fluids recycling system, if any requirement on the mud system, GN Solids America would be ideal supplier you could rely on.

GN Service Team Came Back after The Commission of GN Decanter Centrifuge

Last week, GN service team just come back from Africa, successfully having finished the commission of GN decanter centrifuge. As a leading and top manufacturer of solids control and waste management equipment, GN win and convince its customers not only with high quality, but also with considerate service. Regarding to GN service. One of GN service team just came back from Africa. GN decanter centrifuge has a good reputation in Africa, and until now, GN has sold more than 30 sets of GN decanter centrifuge to Africa this year. Usually, GN exports about one hundred and fifty sets of decanter centrifuge a year, and 70% of them are GNLW363 model( two options, one is fixed speed, the other one is with VFD control panel).

This time, GN has its two decanter centrifuge works in the Africa job site, both of them are GNLW363 Series, one is fixed speed with maximum speed to 3200rpm, but also the speed can be changed with different pulleys. GN service team taught the customer how to change the belt, but it took 3 to 5 hours with enough tools. The other one is with VFD control panel, which makes it more easier and more convenient to change the speed from 0 to 3200 rpm. It can also change the bowl speed and conveyor speed to achieve the best performance.

 

GN decanter centrifuge is used as the final stage equipment to remove ultra fine solids out of the mud with higher speed, or to recycle the barite with a lower speed. GN has excellent service team which is familiar with the working principle and how to adjust speed to get best performance. GN solids control (http://www.gnsolidscontrol.com) could be your right choice for solids control equipment and system.
