Abstract: A well abandonment system includes a jet cutter assembly. The jet cutter assembly includes a first sub including a first bulkhead and a jet cutter tool. The jet cutter tool includes a radial shaped charge and a detonator to detonate the radial shaped charge. A first end of the jet cutter tool is connected to the first sub and a second end of the jet cutter tool is connected to the second sub. The jet cutter assembly may include bulkheads that facilitate electrical communication along a length of the jet cutter assembly. A shock absorber is connected to the jet cutter tool in order to mitigate or prevent shock from impacting the jet cutter upon activation of a perforating gun or components of a tool string that is connected to the jet cutter. The shock absorber may include at least one of a sleeve, biasing member, or wireline.
