S Sumur “X” adalah sumur pengembangan yang dibor dengan menggunakanmetoda pemboran berarah. Sumur “X” berada di Lapangan “Z”, yang berlokasi diKecamatan Rengel, Kabupaten Tuban, Propinsi Jawa Timur. Reservoirsumur “X” terdapat pada Formasi Tuban.Sumur “X” dibor hingga kedalaman 9552,34 ft MD / 6395,71 ft TVDdengan menggunakan lintasan “J” type atau slant type (Build and Hold). Padasaat operasi pemboran sumur “X” sudah berlangsung, terjadi kesalahanpenerimaan data yang di dapat dan pemboran sudah dilakukan 48’ penetrasi lebihdalam dari prognosa yang sudah direncanakan, tetapi sumur belum menemukanTuban Carbonate, sehingga formasi tersebut tidak menemui target reservoir yangdituju. Rangkaian BHA di tarik kembali ke permukaan dan sumur dilakukancement plug hingga kedalaman dimana lintasan side track akan dilaksanakan yaitupada kedalaman 4150 ft MD / 3251,14 ft TVD, dengan perubahan lintasan “J”type atau slant type (Build and Hold) menjadi lintasan “S” type (Build Hold andDrop).Dalam penelitian ini, penyebab terjadinya penyimpangan akan dianalisadan dibandingkan hasil perhitungan antara plan dan aktualnya denganmenggunakan perhitungan metode Minimum Of Curvature. Penyimpangantersebut terjadi karena susunan BHA yang kurang tepat, drilling parameter, ataufaktor geologis.

" "X" well is the development wells were drilled using the directionaldrilling method. The well is "X" in field "Z", which is located in KecamatanRengel, Tuban, East Java Province. Reservoir of "X" wells is present on theformation of Tuban."X" wells drilled to a depth 9552.34 ft. MD /6395.71 ft TVD by using thepath of the "J" type or slant type (Build and Hold). At the time of operation ofdrilling wells "X" already in progress, data reception error occurs in May anddrilling already done 48 ' deeper penetration of prognosis planned well, but havenot found the Tuban Carbonate, so that it does not meet the target formationreservoir of the intended recipients. The series of BHA in drag back to the surfaceand the well done cement plug to a depth where the trajectory of the side trackwill be held in the depths of 4150 ft MD/3251.14 ft TVD, with changes in thetrajectory of the "J" type or slant type (Build and Hold) into a trajectory of "S"type (Build Hold and Drop).In this research, the cause of occurrence of irregularities will be analyzedand compared the results of the calculations between the plan and the actualcalculation by using the method Of Minimum Curvature. The lapses occurredbecause the arrangement of the BHA that is less precise, drilling parameters, orgeological factors
