3 BITTEKHNIKA BITTEKHNIKA company was founded in 1996 and it is still developing dynamically. These are the traditions and innovative technologies in design and production of equipment for sidetracking using a whipstock that form the basis of our company. Basic objections of BITTEKHNIKA Company for years are progress and innovation, extension of product range and customer service to the best of our ability. Today, the company has developed some models of whipstocks for different conditions of installation. Special attention is given to good preparation of sidetracking interval, emergency works and well intervention. To carry the works out we produce sweepers, scrapers, junk, ring and taper mills of unique shapes. In 2011 the range of tools has been expanded we have started designing and production of fishing tools such as overshots, spears, taper taps, die collars etc. Introducing the products BITTEKHNIKA offers not only consulting service to choose the right equipment and its operation modes but also provides technical assistance. Our sales geography nowadays is not limited only to Russia but it is expanding due to our new partners from CIS and Middle East countries. In 2011 BITTEKHNIKA got recertification of quality management system in compliance with ISO 9001:

7 RETRIEVABLE WHIPSTOCK КОI-MF Application: The retrievable whipstock is designed to provide necessary deviation of window mills and reamer mills from the axis of the main wellbore while cutting a window in a production casing. It is also used for deviation of a cutting and drilling tool while drilling an additional borehole in a well. The whipstock is supposed to be set on the bottom. It can be used with starting-and-window mill and watermelon mill that allows to trip, set and cut window in a casing in a single trip. After window cutting operation the whipstock may be retrieved from the well by means of a fishing hook or a die collar. Specification data: Code Casing string diameter, mm L, mm L1, mm L2, mm D, mm Weight, kg КОI-115МF 146,0 (5-3/4) 3955 (156) 1455 (57) 2500 (98) 115 (4-1/2) 175 КОI-135МF 168,3 (6-5/8) 5135 (202) 2035 (80) 3100 (122) 135 (5-5/16) 305 КОI-140МF 177,8 (7) 5260 (207) 2060 (81) 3200 (126) 140 (5-1/2) 370 КОI-145МF 177,8 (7) 5310 (209) 2110 (83) 3200 (126) 145 (5-11/16) 370 5

9 WHIPSTOCK КОP-P Application: It is designed to provide necessary deviation of the window mills and reamer mills from the axis of the main wellbore while cutting ф window in a production casing. It is also used for deviation of a cutting and drilling tool while drilling an additional borehole in a well. After being run in the hole the whipstock is permanently remained there. The feature of the Model P is that the housing of the fixing assembly becomes connected to the ditch after the whipstock is prepared to be run in a wellbore and a movable element used for sliding a wedging die is located inside this housing and operates only at a direct rest of the whipstock on the bottom. Thereby it excludes premature operation of the whipstock fixing assembly during its transportation to the bottom which may occur caused by different casing wall thickness or insufficient preparation of the casing for sidetracking operation. Specification data: Code Casing string diameter, mm L, mm L1, mm L2, mm D, mm Weight, kg КОP-112P 139,7 (5-1/2) 4390 (173) 1890 (74) 2500 (98) 112 (4-7/16) 205 КОP-115P 146,0 (5-3/4) 4390 (173) 1890 (74) 2500 (98) 115 (4-1/2) 225 КОP-190P 244,5 (9-5/8) 6610 (260) 5260 (207) 3500 (138) 190 (7-1/2) 910 КОP-260P 323,9 (12-3/4) 5310 (209) 7590 (299) 4200 (165) 260 (10-1/4)

11 Application: WHIPSTOCK КОP-S It is designed to provide necessary deviation of window mills and reamer mills from the axis of the main wellbore while cutting a window in a production casing. It is also used for deviation of a cutting and drilling tool while drilling an additional borehole in a well. After being run in the hole the whipstock is permanently remained there. The feature of the Model S is that the housing of the fixing assembly becomes connected to the ditch by means of an articulated joint after the whipstock is prepared to be run in the wellbore and a movable element used for sliding a wedging die is located inside this housing and operates only at a direct rest of the whipstock on the bottom. Thereby it excludes premature operation of the whipstock fixing assembly during its transportation to the bottom which may occur caused by different casing wall thickness or insufficient preparation of the casing for sidetracking operation. While seating on the bottom the whipstock is forced to bend relative to the joint axis under the weight of a drilling tool in such a way that the upper part of the ditch is pressed to one side of the string and the bottom part of the ditch to another. It provides better further passage of the tool within the interval of the whipstock installation, as well as allows to install the given whipstock in the intervals with a higher hole inclination angle of the wellbore.
