Wireline Stems (Weight Bars)

At Kriloha Ltd., we supply Wireline Stems (Weight Bars), heavy tubular sections added to wireline tool strings to provide weight and momentum. These stems ensure that tools descend smoothly into the well and deliver sufficient impact force during operations such as valve shifting and fishing. Manufactured from forged alloy steels with heat-treated finishes, Kriloha stems are available in multiple diameters and lengths to suit different well conditions. They are API/ISO compliant and engineered for HPHT and sour gas service. Applications include logging, perforating, valve manipulation, and fishing jobs, where tool weight and momentum are critical. Each stem undergoes hardness testing, dimensional inspection, and fatigue checks, ensuring reliable long-term service. As a supplier and facilitator, Kriloha Ltd. provides custom stem sizes, modular weight assemblies, and quick delivery options, making our weight bars the preferred choice for efficient and effective wireline tool deployment.
