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.

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.

Drilled Solids Control Theory

Drilling fluid is classified as water base utilizing water as the liquid phase. The solid phase of any drilling fluid is either commercial solids or drilled solids. Most commercial solids such as bentonite have a relative particle size of less than one micron(0.000039 inches). Drilled solids are those particles that enter the mud system in the form of cuttings from the bit or back reamer or from borehole debris. These solids vary in size from less than one micron & larger depending on the carrying capabilities of the drilling fluid. Note that spindle speed and the amount of push or pull force require to drill play an important factor on the particle size of the cuttings.

OGEM can produce a complete solid control system

One of the most important objectives in solids control is to remove as many of the large particles as is practical the first time that these solids are pumped out of the borehole. This requires properly designed and installed solids removal mechanical treating equipment sized to process a minimum of 100% up to 125% of the mud circulation rate. Solids that are not removed during the first circulation through the surface equipment are subjected to mechanical degradation by the drill bit, reamers and mud pumps during each circulation cycle until they are too fine for removal by mechanical means. In order to evaluate the removal capabilities of the various pieces of mechanical treating equipment, it is necessary to consider the source of the solids and classify them according to the following sizes:
440 microns or larger – large drilled solids (*cuttings)
74 to 440 microns – sand
2 to 74 microns – silt
0.5 to 2 microns – clay
0.5 microns & smaller – colloids
Note: ( .001 inches = 25.4 microns so 1″ = 25,400 microns )
Benefits of Low Solids In Drilling Mud
1. Increased drilling penetration.
2. Increase bit or back reamer life.
3. Reduce mud cost.
4. Reduce triplex mud pump, mud motor & surface equipment maintenance cost.
5. Reduced clean up & haul off or disposal cost
These benefits are the result of planning prior to boring and are accomplished through the use of properly designed, sized and operated solids removal equipment. It is the responsibility of the boring crew to become knowledgeable in the proper use of the equipment; otherwise the potential benefits may be reduced or nullified.
Methods of Controlling Solids:
1. Mechanical treatment.
2. Chemical treatment.
3. Dilution of mud with water.
4. Discard mud & mix new mud.
All of the above with the exception of Mechanical treatment in most cases are cost prohibitive
Mechanical Treatment
This is the method of mechanically removing solids using shale shakers or hydrocyclone devices such as desanders and desilters. Each piece of equipment is generally limited to the following range of particle removal:
1. Standard shale shaker – 440 micron or larger (also referred to as the scalping shaker).
2. Fine screen shaker – 74 microns or larger.
3. Desanders – 100 microns & larger.
4. Desilters – 15 micron & larger
OGEM desilter is used as the 3rd stage of solid control for drilling mud.

Correctly implemented, each piece of mechanical equipment is effective within a certain particle size range. Utilizing all or a combination of the above equipment throughout your boring program will produce maximum benefits and result in a cost effective means of controlling your solids within an affordable budget.
Mechanical Separation Basics
Mechanical separation equipment employs mass differences, size differences or a combination of both to selectively reject undesirable solids and retain desirable drilling fluid. The desanders and desilters utilize centrifuge force and mass difference between the solids density and liquid density for solids removal. The shale shakers employ a vibrating screen of various micron-sized differences. A standard rig shaker or fine screen shaker is vital to the solids control and should process 100% of the mud returning from the starting pit before allowing this mud to be processed by any of the down stream equipment you may utilize in your solids control system. Located directly down stream from the shale shaker will be one of the hydrocyclone devices:
1. Desander
2. Desilter
These should be sized to process at least 125% of the rig circulation rate while discarding undesirable cuttings & solids down to the 50 micron size range. The desander removes the majority of the solids down to the 100micron size range and prevents the desilter from being over loaded. The desilter removes the majority of the solids down to the 15micron range.

Centrifugal pump is a subclass of turbomachinery technology

Centrifugal pump is a subclass of turbomachinery technology. The main work of this type of pump is to bring up fluids through the transformation of the rotational energy into another energy called hydrodynamic energy. Typically, the rotational energy source is either the turbine, electric motor or engine.
The term centrifugal force pertains description of the movement of energy that is from the impeller's mechanical rotational phase to the fluid's pressure and motion. However, the term centrifugal force is not always required to be used in describing the working mechanism of a particular centrifugal pump. Much like the other pumps, solid control centrifugal pumps are indeed useful despite some criticisms and controversies.

The cantilever pumps or vertical centrifugal pumps are likewise known in many industries. The main feature of this quality pump is the utilization of a special type of shaft and bearing configuration which permit the hanging up of volute just in the sump. Also, this pump model uses throttle bushing, instead of stuffing box in sealing the shaft. In most "parts washer," cantilever pumps are often used.
Centrifugal pump is a subclass of turbomachinery technology

Also, the forth pumps are widely used in oil and mineral industries. The issue concerning the use of this type of pump has something to do with the air content of froth, which blocks conventional pumping force. This problem was vigorously addressed by the oil industry through different approaches. The first approach involved the use of vertical pump with a built-in mud tank; the second approach involved the creation of a pump that has a built-in impeller capable of tearing air bubbles into pieces.
Looking at the paper and pulp industry, holes are mainly done on the pump's impeller. The mechanism is simple: While the air goes out at the rear side of the impeller, an expeller discharges it back to the pump's suction tank. The vanes--either secondary vanes or split vanes--may be incorporated in the impeller.
Regarding the mechanism of a multi-stage centrifugal pump, usually the impellers are mounted either on different shafts or on a single shaft. It is called multi-stage simply because the device has more than one impellers. In addition, for the device to produce higher rate of flow output, the impellers may be adjoined in a parallel manner; and to generate higher level of pressure at the device' outlet, the impellers may be adjoined in series. Often, multi-stage centrifugal pumps are used in boiler feed-water pumps and other similar pumping needs.
