ACT Wireline Stems or Weight Bar or sometimes referred as Sinker Bar provides the weight required to deliver impacts in wireline operations and to overcome the force created by well pressure on the cross section of the wireline. ACT Lead Filled Stems are used to provide additional weight to the tool string, without a change in & length. These are normally used in well bores with high pressures, to counter the force created by well pressure on the cross section of the wireline. However, these should not be used for heavy jarring.
