9 MUD MIXER VACUUM DEGASSER MUD MIXER VACUUM DEGASSER Mechanical mud mixers are designed to prepare the drilling muds and maintain their required characteristics. They facilitate uniform mixing of the mud and additives preventing local overtreatment with chemicals. Among other things, mud mixers keep the weighting material in suspension and minimize the settling of sludge. high power motor, 3 to 22 KW wide range of blade sizes double-row blade mixers can be supplied as an option 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.

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.

12 ENVIRONMENTAL SOLUTIONS CUTTINGS RE-INJECTION 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 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. 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. CUTTINGS RE-INJECTION 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. Note* - the capacity of the unit may vary as it depends on the type of drilled rocks and on the amounts of sand. CUTTINGS RE-INJECTION 22 23

13 CUTTINGS DRYER DEWATERING FLOCCULATION AND COAGULATION UNIT Flocculation and coagulation unit is made on the basis of 40 ft standard container that allows to easily transport this equipment by land and sea transport carriers. CONTAINER-TYPE UNIT CONSISTS OF TWO COMPARTMENTS the first compartment chemical agents dosing unit the second compartment mud laboratory with common monitoring and control system Dehumidification unit is the part of the circulation system for drilling mud treatment and include centrifuge for water removal. As well as tanks for water storage. FUNCTION ECONOMICS 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. 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. CONTAINER SPECIFICATIONS CUTTINGS DRYER 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. 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. overall dimensions comply with the parameters of 40 ft standard container front doors and emergency exits in the laboratory and chemical agents dosing compartments the partitions are made of corrugated metal internal walls and roof are completely isolated heating and air conditioning system can be supplied as an option all our specifications (TU) for performing repair welding operations and welding procedures qualification records were certified by the international experts (Lloyd s Register (LR) / Det Norske Veritas (DNV)) CHEMICAL AGENTS DOSING UNIT total capacity of tanks for liquids storage is 50 m 3 tanks for mixture making are made of stainless steel of SS 304 grade at least one mixer (or more) is provided in each tank/tank section access manholes are provided in each tank/tank section for performing internal work inspection holes are also provided for visual inspection of contaminated / clean water prior to pumping to the storage tanks centrifugal-type pumps for water pumping all the passages have antiskid coating of glass fiber with metal base distribution panel for power supply to the mixers, motors, pumps and lighting process piping (stainless steel of SS 304 grade) and manually operated control valves DEWATERING 24 25

14 THERMAL DESORPTION SYSTEM CUTTINGS SKIPS THERMAL DESORPTION SYSTEM CUTTINGS SKIPS 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. THE TECHNOLOGY IS APPLICABLE BOTH IN ONSHORE AND OFFSHORE ENVIRONMENT AKROS offers thermal desorption equipment in the following configurations: fixed unit (TCC 46E) modular / mobile unit 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.
