摘要 |
A method of adjusting a pressure reduction to occur in a wellbore following firing of at least one perforating gun can include determining a desired free gun volume which corresponds to a desired pressure reduction in the wellbore resulting from firing of the perforating gun, and varying a free gun volume of the perforating gun until the free gun volume is substantially the same as the desired free gun volume. A well system can include at least one perforating gun positioned in a wellbore, the perforating gun comprising multiple perforating charges and a free gun volume, and the free gun volume being reduced by presence of a flowable material about the multiple perforating charges. |
