• Multi engineers, geosciences, & finance together discuss scenario for the completion of the well.

• Finally the (Time –Depth – Cost) curve been generated to monitor Drilling performance.

• TDC curve usually used to presenting Drilling performance

RECOMENDATION:The well was drilled to TD @455m on (07-15 Nov 20xx). The well was IC on (02-07 Jul 20xx) by perforating S4 sand (284.0-285.0m). The well was POP on 07 Jul 20xx at 11:00am. Recompletion was done on (12-19 Sep 20xx) to perforate S5 sand (304.4-305.4m), S6 sand (324.4-326.0m, 327.0-327.6m, 329.0-329.6m), S7B sand (375.0-376.0m, 379-381m) and S7C (392.6-393.6m, 395.0-396.0m). After lowering the pump and set PSN @375m on 27 Sep 2013, the well was POP with initial production at 122BFPD/36BOPD/70% WC.
