Samara Geophysical Company uses in its work only proven and high-quality equipment from the best manufacturers, which has proven effectiveness and fault-tolerance in practice. The offered equipment, technologies, systems along with our high-qualified professionals will help to maximize the potential of both conventional and non-conventional oil fields.
Bottomhole Directional Assembly MWD / LWD, which includes an directional module, a gamma-ray logging module and an electric logging module (multi-probe resistivity meter);
Diameters:
Bottomhole Directional Assembly with electromagnetic communication channel for turbine-rotary drilling
Diameters:
Measurement of volumetric hydrogen content (porosity) of rocks. Includes a compensated neutron-neutron logging tool and a neutron gamma ray logging tool (2NNKt + NGK)
At present, we offer to our customers more than 120 models of Screw Downhole Motors (SDM) with the following diameters:
Failure-free service life of the motors varies from 150 to 200 hours of circulation, depending on the model of SDM.
Turbodrills are used for drilling oil and gas wells with any types of bits and drilling mud density up to 2 g / cm3 and higher; a heat-resistant version allows the operation at temperatures of up to +250 C
Dimensions are as follows:
For special conditions, we can provide motors of special design.
We are ready to provide more than 350 designs of steel and matrix body PDC bits ranging from 83.0 mm to 444.5 mm in diameter, as well as drill heads.
More than 1000 designs of roller cone bits with carbide and steel arms from 95.3 mm to 660.4 mm in diameter
On demand we can provide customized bits:
Double-acting hydraulic jars are most effective for wells with complex trajectories, with the large deviation, when bringing the axial load to the stuck tool is problematic.
Diameters:
Double-acting hydraulic-mechanical jars are effective in straight line wells.
Diameters:
Calibrator is designed for:
Our calibrators are distinguished by their high strength, also by blade structure, providing their equistability and centering properties stability until complete wear.
Diameters: 123,8mm; 139.7mm; 142.9mm; 155.6mm; 215,9mm; 295.3mm; 393.7mm; 490 mm.
Other sizes are available on request.
Centralizers are designed for centering the bottomhole motor (BHM) and assembling of a drill string bottom.
Diameters: 156mm, 131mm, 225mm, 215.9mm.
Other sizes are available on request.
The bit centralizers are designed for centering the bit when drilling oil and gas wells. Centering is caused by the flexible blades of the centralizer. The centralizer belts reinforced by the «Relit» allow to increase the service life of its blades.
Diameters: 131mm, 225mm, 156mm, 215.9mm.
Other sizes are available on request.
The use of Bit Reamers allows us to ream a hole ahead in horizontal sections with a high intensity of curvature changes with no risk of sidetracking, and calibrate the wellbore to the nominal diameter moving both up and down.
Diameters: 123,8mm; 139.7mm; 142.9mm; 155.6mm; 215,9mm; 295.3mm; 393.7mm; 490 mm.
Other sizes are available on request.
Circulation sub (tool) is designed for:
Auto-lock system of multiple activation. The design allows us to inject different types of bridging agent into the absorption zone without pulling the drilling tool out, and also allows increasing the volume of mud pumped through the BHA. The tool is used to facilitate such operations in drilling, development and workover, as:
A tool kit for cutting a «window» in a casing with a hydraulic anchor. It is used for sidetracking by installing wedges in vertical and directional wells. For this design, a cement bridge is not required. The wedge is installed in the specified interval, which reduces the time and financial costs.
A tool kit for cutting a «window» in a casing with a mechanical anchor. This design requires the cement bridge to be installed in the wellbore in a given interval. It is installed by means of abutment of the equipment on the bottom (cement bridge). Axial force causes the slips of the anchor to be extended and fixed against the walls of the casing, thereby the wedge is fixed in the borehole.
