The production of a new flow unit "Monicor-stand-K" was mastered. It allows to determine and transmit corrosion rate and oxygen concentration to the Web-server in real time. In the stationary version, the unit is equipped with 5 solenoid valves and a separator, which prevents hydrocarbons from entering the zone for measuring oxygen and corrosion rate using the LPR method. The unit is controlled by the Monicor-3-GSM-LPR multifunctional device, which receives and transmits information from 2 corrosion sensors, an oxygen sensor and 2 microflow meters to the Web-server, and also controls the operation of all solenoid valves according to a given program. The unit in a stationary version was installed at one of the sewage pump stations of Samotlorneftegaz JSC. The using of the unit provides the possibility to control the ingress of oxygen into the RPM system, which is one of the strongest corrosive agents, and to take preventive measures if it is present. The resolving power of the stand for oxygen is very high - 4 µg/l. If necessary, the unit can automatically regulate the supply of a dosing pump with an oxygen neutralizer.

A Web-based Enterprise Resource Planning (ERP) Web-Eco system was designed for enterprises operating in the field of providing services, manufacturing (packaging) and supplying their own and / or third-party products.
The system provide control of sales: the formation of documentation, storage of additional sales documentation, sales search by principle, change in sales status, sales book formation, costing goods, Sale prices; Purchasing of components and their complete set in commodity units; Warehouse movement. When you enter a new order, an automatic determination of the need for components is made, which ensures that the order is strictly enforced. (Drawings, descriptions, etc.).
Also in the same system, the office work of the enterprise is carried out: storage and automatic numbering of orders, travel certificates, power of attorney, incoming and outgoing correspondence with reference to sales; Accounting, storage and retrieval of information about employees, staffing, time sheets, conducts records of paid and unpaid compensatory time offs and much more.
One of the functions of the system is the formulation, discussion and monitoring of the tasks that are put to the employees within the framework of the enterprise. One of the elements of improving the performance discipline is a daily automatic dispatch with reminders about employees by e-mail, which makes it easier to control the work processes from the middle and top level of the company.
Web-Eco is not positioned as a program for accounting, so it does not take into account all the company's expenses, but only those that affect sales bundling. This scheme is less burdensome than the full ERP-system of the enterprise, both for users and for accountants, whose role is that it is included in the system, Primary sales documentation is formed in Web-eco cooperates with the enterprise and can at any time Be restored from there.
Access to the Web-Eco system occurs from any Internet browser by login-password and SMS, coming to the phone registered in the system. The system implements the demarcation of users' rights to view and modify certain data, a single warehouse for any number of vendors and many other useful functions. The system calculates all changes in the database with the date and user name, the change, with the ability to recover deleted records.
The Web-Eco system is implemented as SaaS (software as a service - software as a service).
Those wishing to use the Web-Eco service can contact us.

OAO "Samotlorneft" conducted a pilot-testing of different protection technologies for wells and pipelines. 20 wells with different characteristics and recovery mechanisms were involved in the testing. The technologies of squeezing the inhibitors into a reservoir, embedding in annular space, pumping into gas lines of gaslift wells were put to the test. 20 Monicor-Probe corrosion control units, 5 Monicor-2 corrosion gages, sample cassettes planted into the wells, and 10 controlled-volume pumps were used during the testing. The water and the oil gas were analyzed at all wells; recovery of reagents was controlled at all wells. On completion of the pilot test one reagent of the four presented, which showed the highest effectiveness, was selected. The test ascertained that the inhibitor treatment of wells brings economic effect only in case of expanding an overhaul period of wells and increasing servicing and total overhaul expenses. In this case the pipeline protection will become a virtually free additional effect. The accumulated experience will help us to conduct works at other customers' deposits with higher cost-effectiveness, predicted results and economically grounded recommendations.
Field testing of inhibitors at OAO "Orenburgneft" water conduits was conducted. For the first time LPR-based corrosion control units (working pressure = 160 atm.) were used for such tests. With the use of the Monicor-2 corrosion gages and the above-mentioned control units it became possible to complete a field testing of one reagent in several concentrations within 3-5 days. As a result, a tightly scheduled field testing of several reagents was conducted.
An automatic update procedure has been added to the "Extra" program. The program is updated automatically at start-up when an upgraded version is detected.
"Extra"'s flow diagram outlining procedure has been revised.
"Extra 5" has been finally translated from InterBase 6.0 to an Oracle 8i EE platform .

Linear polarization resistance (LPR) based Monicor-UKK-160 control units for pressure = 160 atm. have been designed for reservoir pressure maintenance (RPM) system. The first ten units have been installed together with the Monicor-2 corrosion gages at OAO "Orenburgneft" RPM system water conduits and shown high performance. Being satisfied with the testing results OAO "Orenburgneft" has placed an additional order for 40 corrosion control units.
An air-tight circulation test bench has been designed and manufactured recently. An inhibitor bench test for one of the oil-producing enterprises has been carried out. The results of the test allow to recommend it for bench testing in hydrogen sulfide-containing media and for studying corrosion erosion processes (corrosion in high-speed flows). A circulation test bench has the following advantages over a flow test bench:
  1. High flow speed - testing speed at a circulation bench is much higher than at a flow bench.
  2. An inhibitor has time to disperse (in case of a flow bench it can just "fly through" a working cell).
  3. All tests are conducted in laboratory conditions. An air-tight filling and draining of the bench system are vital (the bench may be left on overnight connected to Monicor-2. On completion of a test all data should be inputted in a computer).
