RockySea Petro Self-Tensioning Guy-Wire Workover RigFeaturesA workover rig with guy-line is a double drum workover rig that installs wind loaded guy-wires on the main engine.There is no need to install wind loaded guy-wires with ground anchors, which greatly improves the efficiency of workover operations, reduces operating costs and labor intensity.Also it has features as the following:(1) Suitable for small well site operations, reducing the operation area of the entire workover rig.(2) All te
VIEW DETAILSRockySea Petro Drilling StabilizerDatasheetFunctionControl wellbore trajectory: The stabilizer mainly plays a guiding and stabilizing role in the drilling tool assembly. The installation position of the stabilizer controls the wellbore inclination angle and curvature within the specified range, and also concentrates the majority of the weight of the drill collar on the drill bit, reducing the non wellbore center force and other external forces borne by the drill string and drill bit. With the d
