P Pada operasi pemboran Sumur X di Lapangan Y, banyak dijumpai berbagai macam masalah yang menghambat jalannya operasi pemboran sumur tersebut. Salah satu masalah pemboran yang dijumpai pada Sumur X ini adalah terjepitnya rangkaian pipa bor. Terjepitnya rangkaian pipa bor akan menghambat penyelesaian sumur yang akan mengakibatkan meningkatnya waktu dan biaya pemboran dari yang telah direncanakan. Dalam tugas akhir ini akan diteliti mengenai penyebab terjepitnya rangkaian pipa bor serta penanggulangan yang telah dilakukan. Hal - hal yang dapat menyebabkan pipa terjepit seperti, aspek hidrolika, lumpur, kestabilan lubang bor, jenis formasi dan lithologi batuan juga. Jenis – jenis pipa terjepit seperti diffrential sticking, mechanical, key seat, pack off. Metode yang dilakukan dalam menanggulangi pipa terjepit seperti metode renggang lepas, sirkulasi, perendaman, dan metode terakhir back off. Evaluasi yang dilakukan pada tugas akhir ini adalah berkaitan dengan lumpur yang digunakan beserta dengan rheologynya dan hidrolika pemboran. Hal ini dilakukan, sehingga operasi pemboran dapat terus dilanjutkan dan penyelesaian sumur dapat dilakukan dengan baik. Stuck pipe pada Sumur X terjadi pada trayek 26 dengan klasifikasi penumpukan cutting dikarenakan, lumpur pemboran yang tidak sesuai dan rheology yang digunakan tidak optimal serta pompa dari aspek hidrolika. Metode yang dilakukan dalam penanggulangan stuck pipe pada sumur X ini, yaitu dengan back off, dikarenakan dengan metode work on pipe, sirkulasi, dan perendaman,namun pipa tidak dapat terlepas. Pemboran dilanjutkan dengan side track untuk mencapai target displacement yang direncanakan.

D During drilling operation in Well X on Field Y, there were many problems occurred. Those problems hampered the smooth operation of drilling in that well. One of drilling problems occurred seriously during the operation was the stuck of the series of drilling pipe. This pipe stuck event clearly extend the drilling operation s time and cost compared to the planned one. In this final task assigned to me to conclude my study period, it will be examined on the cause of stuck on the drill pipe, and its handling actions which have been done. In addition to that, the things that can cause a pipe stuck, such as aspects of hydraulics, mud, borehole stability, and including formations types and lithology of rock. Also discussed the types of pipe stuck such as differential sticking, mechanical, key seat, pack-off. As well as, the methods should be performed in handling the stuck of drilling pipe such as work on pipe, circulation, immersion, and the last method back-off. Evaluations were made on this final task is related to the mud used along with its rheology, and drilling hydraulics This is performed, so that the drilling operation can be continued, and the completion work of the well can be accomplished successfuly. Stuck pipe in the well trajectory X occurred at 26 trajectory with cumulative of cutting classification were caused by the application of unsuitable drilling mud, rheology was not optimally implemented, as well as the pump deployed from the aspects of hydraulics. The method performed to handle the stuck pipe in the well of X was back-off method, due to the implementation ofother methods such as work on pipe, circulation, and immersion did not successfully release the pipe. Drilling then continued with a side track to achieve the displacement target as planned.
