B Based on the packer tools work,Packer separated into two type.Mechanical packer and hydraulic packer. The workings of these two packer is acommon way of working that is used in many well. The purpose of this thesis isevaluation of production packer election which can be used in field M. Most ofthe wells in this field have a depth of more than 2000m this depth can giveproblems in the process of setting. Mechanical rotation is performed on thesurface will not reach the target due to the difference a great distance . Mechanicalrotation can still be done , but the level of accuracy of the rotation will be verybad .The other packer are using hydraulic pressure from pump in surface toactivate the slip and seal.compared with a mechanical packer,hydraulic packer hasno serious problem with setting in a deep well.Well completion analysis is the calculation used to calculate the effectsthat occur when the packer set. including piston effect,ballooning effect,bucklingeffect and temperature effect. Well completion analysis will produce two results.The first result is a tubing length changes ,this change is caused by base effectsthat occur below the surface . In addition to changes in the length of thiscalculation will return the amount of force that will be given to the packer. theresults of these calculations the length of tubing changed 48,7 inch tubing andforce that occurred in packer at 14.418 lbs packer not free to move . The result ofthis calculation gives the conclusion that the hydraulic packer used in these wellsis not problematic and even recommended to use.
