H-FLOWH-FLOW SYSTEM – is a specially designed drilling fluid for drilling in high-density reservoirs. This system is used to drill horizontal sections of the wells under abnormally high formation pressures.

Special chemicals and polymers allow maintaining barite-free mud with specific gravity above 1.30 g/cm3 and up to 1.9 g/cm3

MUD SYSTEMS WITH FINE GRADE BARITE

The composition has been designed based on the modified starch and fluid sweeps with appropriate pH to ensure good structural bonding.

It does not contain any biopolymers.

Mud cake may be removed by acid treatment.

It is possible to use appropriate chemicals to properly adjust completion fluid properties using salts of heavy metals.

Fine-grade barite is mostly used to prepare water-based and oil-based drilling fluids characterized with high density and low rheological properties. As a rule, a mud system shall have improved structural properties in order to provide appropriate sedimentation stability for heavy-weight mud systems. The sizes of colloidal particles of fine grade weighting agent may significantly reduce rate of sedimentation, thus creating conditions for the use of mud compositions with lower rheological properties.

SPECIAL FEATURES

ability to mix high-density drilling fluids with low content of solids.

minimal contamination of pay zone.

good inhibitive properties

rheological properties of biopolymer mud are characterized with low plastic viscosity, non-progressive gel strengths, and high values of viscosity at low shear rates.

ADVANTAGES

it is a good alternative to barite mud systems, as it does not affect the properties of the production interval.

the rheological properties of biopolymer mud allow reduced bottom pressure fluctuations.

low emergency/ failure occurrences and increased penetration rates under abnormally high formation pressures.

MICRO-BARITE APPLICATIONS

increase of sedimentation stability in water-based and oil-based mud systems

ability to design mud systems to drill exploratory wells in abnormally high formation pressure conditions through the optimization of rheological properties

facilitation of completion operations due to the use of bottom-hole strainerst

improved performance of mud cleaning equipment

rectification of drawbacks typical for liquid concentrate of fine-grade weighting agent

27New technologies | 26

SYNTHETIC MICRO-COLMATANTMicro-colmatants (plugging agents) are mostly used to improve the stability of boreholes drilled using water-based mud. Fine particles of mud seal micro-fractures, and prevent the penetration of filter cake into the structure of unstable clays and shales.

FUNCTIONS

A new synthetic colmatant (plugging agent) is a mixture of special water-soluble and oil-soluble polymers. Dependent on the base of the drilling fluid, some polymers dissolve completely, while some of them form aggregates varying from 5 to 800 micron. The aggregates form elastic membrane, which prevents penetration of filter cake deep into formation, thus strengthening the formation under the overbalance pressure conditions. In minimal underbalanced conditions this membrane is easily removed due to the absence of the inner filter cake. This additive may be used to drill the production interval with the minimal risk of reduction of permeability in the bottom-hole area.

SCOPE OF APPLICATION

it may be used in all types of water-based and oil-based mud systems

it is highly efficient to reduce fluid loss in high pressure and high temperature conditions

the recommended concentrations may vary from 12 to 20 kg/m3 –dependent on the application conditions

It is compatible with production formation fluids and rocks, and it does not affect the recovery of permeability after drilling

VACUUM DEGASSER The AKR series Vacuum Degasser is a special-purpose device for quick gases removal from the drilling fluid. Invasive gases removal is a significant treatment process aimed at returning mud gravity, stabilizing viscosity and reducing drilling cost. Moreover, the AKR Vacuum Degasser could also be used as a heavy-power agitator ensuring further treatment by desander and desilter.

FEATURES & BENEFITS

AKR Series Vacuum Degassers are able to service the needs of any application. It is usually installed after the shakers. Each degasser effectively 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.

WASTE TREATMENTTHERMAL DESORPTION SYSTEM

Thermal Desorption of Drill Muds and Cuttings was first used in the beginning of 1990s. Hence, this technology was improved significantly due to the introduction of the stringent environmental requirements and standards followed by the increased recovery of hydrocarbons. The amounts of hydrocarbon mixtures used in drilling fluid systems have increased due to the use of diesel fuel, mineral oils and wide range of synthetic oils.

Different types of hydrocarbons are present in drilling wastes. Drill cuttings include drilled rock, water, oils, crude oil and different additives used in drilling fluid systems. The

wastes contain hydrocarbons mixed with water and cuttings, as well as different emulsions and hydrocarbons from the pores of drilling cuttings.

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.

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

DEWATERING

Dewatering unit is designed to reduce drilling waste disposal costs by processing drilling wastes and by recycling water, which can be re-used to mix drilling fluids, or for any other technical needs. The unit also converts large amounts of waste drilling fluids to a small volume of solids, thus significantly reducing associated waste disposal costs.

The Dewatering unit function is based on physical and chemical process of coagulation, when fine suspended particles in the treated fluid collide with each other and stick together, forming larger particles, which are further removed by the centrifuge. The unit treats drilling waste water, it recovers waste drilling fluids, and provides safe disposal of mud components in dedicated landfills.

For mobilization and installation purposes, the unit is integrated in the standard shipping container, which can be transported by any carriage, provided all appropriate transportation requirements are properly identified and met.


CUTTINGS DRYER

FUNCTION

A Cuttings 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.

WASTE TREATMENT

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 dryer 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.



WASTE DISPOSALWASTE INJECTION

Drill-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 drill 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.

PROBLEMS

Storage, treatment and disposal of drilling cuttings in the environmentally sensitive areas and in severe weather conditions may create serious problems for economics, logistics, production and obtaining of appropriate permits and approvals. The oilfield waste management is one of the most critical challenge for the Russian oil and gas industry.

SOLUTIONS

Waste reinjection 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.
