Shell drilling rig towed after running aground off Alaska

A giant floating drill rig that ran aground a week ago on a remote Alaska island arrived as planned Monday in the shelter of a Kodiak Island bay after being towed about 72 kilometres through swells as high as 4.5 metres, officials said.

The Royal Dutch Shell PLC vessel was lifted off rocks late Sunday and towed away from the southeast side of Sitkalidak Island, where it sat exposed to the full-on fury of Gulf of Alaska winter storms since grounding near the beach there on New Year's Eve.
The Kulluk — a circular barge with a diameter as long as nearly three basketball courts — was towed for about 12 hours to the protected waters in Kiliuda Bay, where it will undergo further inspection, including an underwater look at its hull.
"We could not be more impressed with the calibre of the response and recovery crews who were safe and meticulous in their effort to move the Kulluk offshore," Shell Alaska spokesman Curtis Smith said by email.
The vessel will remain in the bay 69 kilometres southwest of the city of Kodiak until inspectors review its condition and the Coast Guard clears it to travel. Shell incident commander Sean Crutchfield said there's no timetable for departure.
The massive effort to move and salvage the ship involves more than 730 people, according to the Unified Command, which includes the Coast Guard, Shell and contractors involved in the tow and salvage operation. Eleven people are aboard the ship — a salvage crew of 10 people and one Shell representative
Shell earlier reported superficial damage above the deck and seawater that entered through open hatches. Water has knocked out regular and emergency generators, but portable generators were put on board last week.
Rig had been headed to Seattle
The Kulluk is 81 metres in diameter with a derrick in its middle and a funnel-shaped, reinforced steel hull that allows it to operate in ice. Its derrick rises 48.7 metres. It drilled last year in the Beaufort Sea and was headed to Seattle for upgrades and maintenance when it ran into trouble.
Its towing vessel, the 110-metre anchor handler Aiviq, on Dec. 27 lost its line to the Kulluk in heavy seas and hours later lost power to all four of its engines, possibly due to contaminated fuel.
Four reattached lines between the Aiviq or other vessels also broke in stormy weather. The Aiviq on New Year's Eve again broke its line, leaving the Kulluk attached to the tugboat Alert.
Inspections after the grounding determined that the Kulluk could be towed, and the Aiviq on Sunday reattached a tow line. Tension was added to test the line Sunday night and increased as high tide approached, Crutchfield said.
Inspections will involve an underwater look at the hull with divers or remotely operated underwater vehicles or divers or both, he said.
The Kulluk will be tethered to two tugs in the bay and will attempt to set its anchor. If that doesn't work, he said, additional tugs will be used to keep it in place.
A tug trailing the drill vessel used infrared equipment to watch for oil sheens and reported no petroleum discharge.

OGEM supplys oil drilling equipment

OGEM supplys oil drilling equipment including shale shakers and repair parts. Shale shakers are devices that remove drill cuttings from the drilling fluid that is used for boring holes into the earth. Controlling the solids in drilling fluid is an important component of the cost of drilling, so research into improved shaker design is ongoing.

OGEM supplys shale shaker
Shale shaker design – Shale shakers typically consist of large, flat sheets of wire mesh screens or sieves of various mesh sizes that shake or vibrate the drill cuttings, commonly shale, across and off of the shale shaker screens as the drilling fluid (mud) flows through them and back into the drilling fluid system. This separates the solid drill cuttings from the fluid so that it can be recirculated back down the wellbore. In oilfield industry, linear motion shale shakers are widely used.
Shale shaker screen panels – Screen panels play a major role by removing particles larger than the mesh size. Screen selection is critical since shaking is the primary stage in the removal of solids. Improper screen selection can lead to de-blinding, loss of drilling fluids, premature pump part failures, overloading of other solids removal equipment within the solid control systems, decreased service life , reduced flow rate capacity, and serious problems in the wellbore.

Horizontal Directional Drilling Mud System

Horizontal directional drilling (HDD), also known as directional boring, directional drilling, horizontal drilling, or slant drilling, is a method of treachless technology. In oil & gas industry, it is used to access to the oil & gas bearing reservior from a laterally vertical well. It can also be used for utilites to get cross from one point to another without distroying the existing ground or obstacles, usully crossing under rivers, road, roadway, and other existing structures. Drilling mud circulation system would also be used to smooth directional drilling processing.
Horizontal Directional Drilling

For horizontal directional drilling (HDD), a drilling path should be pre-ditermined from the surface of the ground with a minimum disturbance. A pilot borehole is then drilled by reamer along the drilling path. The purpose of directional drillig is mainly to install & connect pipes & conduits to transport different type of fluids & other material. As directional drilling is often not much deep, mainly boring the surface formation, so it mainly use water or water based drilling fluids to suspend and carry the drilled solids to the surface of the ground.
Directional drilling for utilites is often much faster than oil & gas drilling. A quick movable drilling mud system is often needed. Different from oil drilling mud system which is normally placed directely on the ground, HDD mud system normally has wheels to move, and draged by a tractor.

What is a Drilling Rig?

Horizontal, vertical – drilling methods and construction are discussed not just by professionals, but your grocery store cashier, taxi driver, or even elementary students. Drilling rigs are used to drill an oil well, which will extract oil or natural gas. Some drilling rigs are built up and transported from site to site, but most often rigs are built up on rig mats for a specific well.

For more information on the basics of a drilling rig – we suggest checking out the following places:
OSHA provides a really great look at the parts of a drilling rig, by using an illustrated glossary of components of a drilling rig. You’ll also find a through explanation of the completed well .
For more in depth information NaturalGas.org provides a long explanation of the basics of drilling rigs and the process.
Fox Oil Drilling provides a page of oil drilling information and imagery, explaining the pieces and parts of a completed oil well. This image is very basic and easy to understand, from the wellhead to the counter balance.
Finally, for students and young children, the US Department of Energy offers a basic introduction to the oil well process in a simple and easy to understand way.

Some skills of purification in solids control system

As you all know ,Solids control equipment play a very important role in oil exploitation,and the maintenance of solids control is also a very important part for its purification handling .Following are some skills used in purification of solids control equipments.
solid-control-system

Solids control equipment includes many other equipments,We need to clean every different equipment step by step,when make purification .and when gas migrate to the drilling fluids ,we can make the mud of purification from shale shaker go into the setting pit of mud purification tank,and then ,we can use the pumping function of vacuum pump within degasser,causing negative pressure within vacuum tank,which can make separation within degasser through the function of barometric pressure. then the separated gas discharge to the top of derrick and pull out the air.
If no gas in the solids control system,we may act degasser as a big agitator for the drilling mud,and then,which can not keep the mud sediment in purification tank in order to gain cleaning mud from shale shaker.and the underset enter into the special tank under mid-speed centrifuge so that separating once again through the second high-speed centrifuge ,after separation ,the mud included heavy crystal go back to the mud purification tank ,and keep the performance of mud steady .
drill bit
When the mud under the site of aggravation in the solids control system ,Because the centrifuge not only harm the solids phase removing ,but also remove the weight material together ,this way can reduce the mud weight quickly ,lost material heavily .we need to use two sets centrifuge in series in order to avoid loosing weight material and get the aim of removing harmful solids phase.According to the request of complete mud purification system in solids control system,the handling capacity of desander need to achieve normal amount of mud flow above ,plus ,which can make the mud purification fully and reduce the content of sand in drilling mud .

Shale shakers are components of drilling equipment

Shale shakers are components of drilling equipment used in many industries, such as coal cleaning, mining, oil and gas drilling. They are considered to be the first phase of a solids control system on a drilling rig, they are used to remove large solids also called cuttings from the drilling fluid, more commonly called “Mud” due to its similar appearance.
Drilling fluids are integral to the drilling process and, among other functions, serve to lubricate and cool the drill bit as well as convey the drilled cuttings away from the bore hole. These fluids are a mixture of various chemicals in a water or oil based solution and can be very expensive to make. For both environmental reasons and to reduce the cost of drilling operations drilling fluid losses are minimized by stripping them away from the drilled cuttings before the cuttings are disposed of, this is done using a multitude of specialized machines and tanks.
Shale shakers are components of drilling equipment

Shale shakers are the primary solids separation tool on a rig. After returning to the surface of the well the used drilling fluid flows directly to the shale shakers where it begins to be processed. Once processed by the solids control shale shakers the drilling fluid is deposited into the mud tanks where other solids control equipment begin to remove the finer solids from it. The solids removed by the shale shaker are discharged out of the discharge port into a separate holding tank where they await further treatment or disposal.
Shale shakers are considered by most of the drilling industry to be the most important device in the solid control system as the performance of the successive equipment directly relates to the cleanliness of the treated drilling fluid.
