Hammock Activity Exercise

Scenario: A well is experiencing production issues and requires a workover operation. The well is 10,000 feet deep with a 9-inch diameter casing. The rig has a lifting capacity of 100 tons. The crew is experienced in using hammock systems.

Task: Determine if hammock activity is a suitable method for this workover operation, considering the well conditions, rig capability, and crew experience. Justify your answer.
