MUD GUN

ADVANTAGES AND FEATURES

AKR 45

AKROS offers AKR series mud hoppers, designed and manufactured to enable rapid and efficient dosing and mixing of chemical and additives while preparing and maintaining drilling fluids. The hopper function is based on the venturi effect, when the pressure of a flowing fluid decreases passing through a restriction, thus allowing to add appropriate dozes of polymers, barite, bentonite and other powder additives.

The hopper may be place on the skid with the centrifugal pump, thus simplifying the installation of mud cleaning equipment on the drilling rig.

Mud gun is a low pressure jet mud mixer designed for hydraulic mixing of the drilling mud. Mud guns are installed on the

mud tanks.

▪ rotating mechanism permits manual control of the horizontal fluid flow from the jet nozzle between 0° and 360°

▪ the jet nozzles are made of wear-resistant material

▪ specially designed nozzles inject the fluid in three directions simultaneously

VACUUM DEGASSER

VACUUM DEGASSER

AKR series vacuum degassers are able to service the needs of any application.

It is usually installed after the shakers. Each degasser effectively and efficiently removes gases from gas-cut mud, thus

ensuring that the proper mud weight is pumped down hole. In doing so, the degassers are able to aid in the prevention of

potential blowouts.

Unlike the traditional vacuum degasser, AKR vacuum degasser is a self-contained unit, AKR vacuum degasser is

monitored by level sensor to protect over suction of the flids. The gas-cut mud is drawn into the degasser by a vacuum

created by a regenerative vacuum without needing centrifugal pump.

AKR 270 degasser can act as a big agitator for the drilling mud, which helps the treatment for desander and desilter.

CENTRIFUGAL DEGASSER

CENTRIFUGAL DEGASSER

WORKING PRINCIPLES

Centrigugal degasser is a new type degasser, specialized in processing gas cut drilling fluids. Normally it is installed

after shale shaker and widely used in various solids control systems, and it is very important for recovering mud weight,

stabilize mud viscosity performance, reduce drilling cost. Meantime it can be used as a big power blender. Its advantages

are large capacity, high rate of degassing, less area required, low energy consumption, easy operation and maintenance.

Via the rotating impeller, the degasser sucks the drilling fluid into the vessel. The fluids will stay at a level higher than the

gas cut drilling fluid and then a cylindrical liquid layer with inverted cone shape space in the middle will be formed. Drilling

fluid is discharged from discharge port along a tangent line.

With the impeller rotating, bubble breaks, gas will be extracted from liquid, and finally accumulate in the cone shape space

as the lower density. Pressurizing unit (similar to exhaust fan) will suck air through the narrow channel between the air

distribution disk and air separation ring into the discharge cone, and then gas manifold, braided hose and pressuring unit,

finally discharge the gas out through pressuring device with pressure.

SCREW PUMP

SCREW PUMP

AKR 30

The AKR series screw pump is a single screw pump. The pump is an ideal pump for feeding to decanter centrifuge without

shearing or agitating the drilling mud. The main parts are screw shaft (rotor) and screw shaft bushing (stator). Because of

the special geometry shape of the two parts, they form pressurize capacity separately. The fluids flow along with the shaft,

inner flow speed is slow, capacity remains, pressure is steady, so it will not generate vortex and agitating.

The shaft of the pump is made from stainless steel, AKR series pump is available for option with complete stainless steel

body, it can drive by coupler, or adjust the speed by using variable speed motor, Triangle V-belt, gear box, etc.

AKR series screw pump is with less accessories, compact structure, small volume, easy maintenance, rotor and stator

are wear parts of this pump, it is convenient to replace.

The stator is made of elastomeric material, so it has particular advantages than other pump to transfer the fluids. With

high viscosity and hard suspended particles included.

WHAT IS THE CRI?

Cuttings re-injection is an economically sound and environmentally friendly long-term solution for cuttings disposal in

remote areas. The available field-proven practices allow to minimize costs and HC emissions typical for the other drilling

wastes disposal methods. Also this method excludes any other current or future liabilities related to the cuttings disposal.

It is a waste disposal technique where cuttings and other oilfield wastes (such as mud slurry, old drilling fluids, waste water

from the rig) are mixed into a slurry with water and pumped at high pressure into hydraulically created fractures below the

surface for safe disposal of such wastes.

SAFETY AND QUALITY ASSURANCE

The safety and quality assurance process applied for the CRI purposes provides an integral approach to all aspects of the

CRI project. Based on the analysis of the data provided by the Client our specialists design special solutions which are

fully optimized for each particular project. Our CRI quality assurance and safety program is a unique product in oil and gas

industry as it allows verification of quality parameters before, during and after re-injection. This program enhances the

safety of the project, including its economical profitability.

SLURRIFICATION UNIT

FUNCTION

The unit is an integral part of the drilling waste injection system; it is designed to process different types of wastes and to

convert them into slurry for further containment before injecting the slurry into formation. This unit has a small footprint and

it can be installed in a relatively small area. A conventional standard slurrification unit consists of the following components:

▪ coarse tank, 55 barrels

▪ fines tank, 55 barrels

▪ two holding tanks, 100 barrels each

▪ hydration tank, 55 barrels

OPERATING PRINCIPLE

Drilling wastes are first collected into the coarse tank where they are diluted with process water and / or liquid wastes.

At the same time the large particles are broken down in the continuous circulation process activated by centrifugal

pumps and power-driven agitators. There is an operator’s station on the top of the tank; it is equipped with the control

panels to control the slurrification process.

The drilling wastes are then directed to the shale shakers installed on the holding tanks. Liquid wastes and solid particles

(<300 micron) are collected in the holding tanks, while the large particles, separated by the shale shaker, are directed

to the blender installed on the top of the fines tank. Treated wastes are disintegrated in the fines tank by continuous

circulation process, and then the material is fed into the shale shakers.

The dehydration tank is designed to improve the rheology of the slurry by adding chemicals through the hopper installed

on this tank.

When the appropriate parameters have been reached, the slurry is directed to the HP pump for further injection into

formation.

The total power consumption of the unit is 510 kW, the capacity is 240 m3/day.

Note* - the capacity of the unit may vary as it depends on the type of drilled rocks and on the amounts of sand.

SOLUTIONS

Cuttings re-injection back into formation is an ideal solution, which complies with the requirements applied to drilling and

well production operations in the Russian Federation. Our field-proven experience allows to offer a cuttings re-injection

package, which will benefit the waste disposal process in the most complicated work conditions by providing efficiency and

economic parameters satisfying all appropriate requirements of the environmental legislation.

ECONOMICS

Storage and transport practices used for further treatment and disposal of wastes present additional challenges, that can

be extremely costly for each project. Transportation of wastes is often impossible due to the poor weather conditions. In

some cases, such restrictions may seriously affect the project and make it non-profitable. The cuttings re-injection system

has been thoroughly developed and designed to settle such problems by treating cuttings on the rig or in adjacent areas thus

reducing or excluding the necessity to transport cuttings from the rig or to truck them to distant locations. This approach

gives an opportunity to the development of new oilfields which were inaccessible due to the lack of road infrastructure.

ENVIRONMENTAL

Cuttings re-injection method is a solution which fully complies with the requirements of the Russian Law. In addition to

compliance with environmental regulations and zero-discharge polices it ideally fits for environmentally sensitive areas,

requiring serious restrictions for HC emissions versus any other waste disposal methods and technologies.

CUTTINGS DRYER

FUNCTION

A cutting dryer can reduce total oil-based mud losses thus

decreasing the volume of cuttings, while drilling wells using

an oil-based drilling fluids.

APPLICATIONS

Offshore and onshore projects where the recovery of valuable

drilling fluid from cuttings, as well as recovery of oil-based

mud and return to the active system are the priorities.

PROBLEMS

More stringent cuttings-discharge regulations have

pressured operators and drilling contractors to reduce

drilling waste volumes and recover premium products for

reuse.

SOLUTIONS

The cuttings dryer features a state-of-the-art design that

can process varying amounts of cuttings and fluids, typically

up to 60 tons per hour. Dry solids discharged from the dryer

are typically <5-6% oil content.

ECONOMICS

The cuttings dryer improves overall cost-efficiency, producing

reduced amounts of extremely dry cuttings for disposal and

recovering valuable fluid for reuse. It is effective with oil- and

synthetic-base drilling fluids.

ENVIRONMENTAL

The dryer minimizes waste volumes , dramatically reducing

disposal costs. In the quest for improved environmental

practices, operators need solid-control solutions that take

liquids / solids separation to a new level. The cuttings drier

incorporates a high-speed vertical centrifuge, that achieves

maximum liquids / solids separation in large-volume

processing. This gives operators a critical advantage in

meeting increasingly stringent environmental rules for

cuttings disposal.

Cuttings skips are designed for containment and transfer of drilled rocks and other wastes produced from well drilling.

The design of cuttings skips provides heavy-duty durability and reliability, that’s why cuttings skips are widely used in

offshore drilling, where the most stringent requirements are applied.Due to portability of equipment and for stacking

convenience, drill cuttings collected in skips may be shipped by water transport, as well as by road and railway transport.

The cuttings skips may be used under extreme temperatures from minus 40°C to plus 50°C without deterioration of

strength and sealing properties.

THERMAL DESORPTION SYSTEM

THERMAL DESORPTION SYSTEM CUTTINGS SKIPS

THE TECHNOLOGY IS APPLICABLE BOTH IN ONSHORE AND OFFSHORE ENVIRONMENT

The treatment technology is based on the thermal processes resulting in evaporation of liquids from drilling cuttings,

including: hydrocarbons and water. Water evaporates first, turning into water vapour, and hydrocarbons evaporate later,

as they have a higher boiling point. Hydrocarbons are separated from water during the two stage condensation process,

based on the same principles.

The hammer mill generates large quantities of heat during the grinding process, thus breaking cuttings and removing

liquids, including pore fluids. The design provides reduction of thermal energy to minimum and simultaneous removal of

liquid components with recovery of hydrocarbons for further re-use in oil-based drilling fluids.

AKROS offers thermal desorption equipment in the following configurations:

▪ fixed unit (TCC 46E)

▪ modular / mobile unit

ADVANTAGES

▪ it removes 99% of solids

▪ it is environmentally friendly

▪ it entails no direct combustion

▪ recovery of oil or synthetic-based drilling fluids and water
