Results from this study can be useful in planning well kill operations. The planning process can be summarized as follows:
- Determine the capacities of the mud/gas separation equipment to determine the maximum circulation rate that this equipment can tolerate.
- Compare this rate to the optimum circulation rate to remove gas from the horizontal portion of the hole.
- If the minimum rate to remove gas from the horizontal section exceeds the maximum rate that can be handled by the surface equipment, the kill operation should begin at the higher kill rate to remove gas from the horizontal section.
- Once the casing pressure begins to rise due to the gas entering the non-horizontal section, the kill rate should be reduced.
A thorough explanation can be found in Parts II and III.
