The Packer Calculation program will help you avoid having a packer unset during testing or squeezing operations.
The program also includes tubing movement calculations and a field estimate production rate calculator along with BHT chart
The program covers both compression and tension packers also maximum allowable swabbing depth for upstrain packers. Since the forces are related to several differing factors you you have the option of selecting the type of flow, whether there is no flow, mud/brine in the tubing, gas or oil flow. Then select the type of packer upstrain (tension) or set down (compression). This data is used in the forces applied to a pkr calculations.
