Abstract

Idle Wells are the wells which are inactive due to an extended close down in production or injection of fluids. The well usually shut in because of low production from the accessed reservoir. Well also will be considered idle when there is some mechanical problems like surface control subsurface safety valve problem that lead to shut-in of the well. Also, the well might be inactive when there are some facilities problems like broken gaslift flowline. But the major idle well that needs extra attention is the idle well which has possiblity to access other potential reservoir eventhough the well is considered idle previously due to depleted of current accessed reservoir. Thus, how to reactivate the idle well? Before reviving the idle well, the factor that lead the well to be inactive should be investigated first. Is it due to some mechanical problems or because of depleted reservoir reserves? Normally, if the well is idle because of mechanical problems, the parts which are broken can easily be replaced or repaired. But, if it is because of low production rate, the approachment will be different. One of common approach is Insert String Job. But this project will focus more on the enhancement job that will reactivate the idle well. In addition, the well needs to be reactivated because Idle well can still provide the states and nation with much needed production. For instance sidetracking a well. This is one of the methods to revive the idle well. Sidetracking is drilling a directional hole to deepen a well or to relocate the bottom of the well in a more productive zone, which is horizontally removed from the original well. Thus, by sidetracking, the idle well can accessed to the other reservoir and thus reactivate the well. The same concept is applied to the additional perforation enhancement job. It simply creates a communication between the potential reservoir with the idle well. So, the idle well can reproduce back with different reservoir from the current one.
