Abstract

L Lumpur pemboran yang digunakan dapat menentukan kecepatan pemboran, efisiensi, keselamatan dan biaya pemboran sehingga harus mempunyai kemampuan pengangkatan serbuk bor (cutting) yang baik. Pengangkatan cutting yang tidak optimal akan menyebabkan cutting mengendap kembali ke dasar sumur dan menimbulkan permasalahan dalam operasi pemboran. Pada tugas akhir ini dilakukan evaluasi pengangkatan cutting pada sumur AU-17 trayek 12 Â¼â€ dan 8 Â½â€ menggunakan lumpur berbahan dasar KCl Polymer karena formasi batuan yang ditembus terdapat kandungan clay sehingga mencegah terjadinya swelling claypada formasi. Pada Sumur AU-17 diperoleh efisiensi waktu pengeboran 23 % lebih cepat dari rencana pengeboran yang telah dibuat. Parameter keberhasilan kemampuan pengangkatan cutting dapat menggunakan metode Cutting Carrying Index (CCI) dengan hasil >1, Cutting Transport Ratio (CTR) >50% dan Cutting Capacity Annulus (CCA) < 5%. Salah satu faktor yang memengaruhi proses pengangkatan cutting hingga ke permukaan, diantaranya yaitu kecepatan fluida di annulus yang sebagai fungsi dari rate pemompaan yang diberikan dan luas area di annulus, konsentrasi pada cutting di dalam lumpur pemboran, laju penembusan (rate of penetration). Pengevaluasian pengangkatan cutting didapatkan hasil pada trayek 12 Â¼â€ dengan metode Cutting Carrying Index (CCI)didapatkan nilai 2,273 â€“ 9,454, metode Cutting Transport Ration (CTR) didapatkan nilai 71,360 % â€“ 81,187% dan pada metode Cutting Concentration in Annulus (CCA)didapatkan nilai 4,822 % â€“ 4,907 %. Pada trayek 8 Â½â€ memiliki hasil pengangkatan cutting dengan metode Cutting Carrying Index (CCI)didapatkan nilai 4,852 â€“ 14,492, metode Cutting Transport Ration (CTR) didapatkan nilai 86,199% - 90,107% dan metode Cutting Concentration in Annulus (CCA)didapatkan nilai 4,708 % - 4,782 %. Pada penelitian ini membuktikan bahwa komposisi lumpur menentukan keberhasilan kegiatan pemboran sehingga parameter lumpur yang akan digunakan sangat berpengaruh. Parameter pemboran seperti rate of penetration (ROP) yang digunakan terlalu tinggi dan flowrate pompa yang terlalu rendah akan membuat proses pengangkatan cutting yang buruk yang menyebabkan pengendapan cutting sehingga keduanya harus ditentukan dengan tepat untuk menghasilkan hole cleaning yang baik.

D Drilling mud used to determines drilling speed, efficiency, safety, and drilling costs, so it must have good cutting lifting. . If removal of cutting is not optimal which causes cutting to settle back to the bottom of the well, there will be problems in drilling operation. In this final assignment there will be a research about an evaluation of cutting transportation at the AU-17 well on the 12 Â¼ " traject and 8 1/2" traject used KCl Polymer based mud because the rock formations that are impregnated contain clay so as to prevent swelling of clay in the formation.At AU-17 Well, the drilling time efficiency is 23% faster than the planned drilling. The success parameter of cutting lifting ability can use the Cutting Carrying Index (CCI) method with results> 1, Cutting Transport Ratio (CTR)> 50% and Cutting Capacity Annulus (CCA) <5%. One of the factors that influence the cutting process up to the surface, including the speed of the fluid in the annulus as a function of the given pumping rate and the area in the annulus, the concentration of cutting in the drilling mud, the rate of penetration. Evaluation of cutting removal results obtained on traject 12 Â¼ "with the Cutting Carrying Index (CCI) method obtained values of 2,273 - 9,454, Cutting Transport Ration (CTR) method obtained values of 71,360 - 81,187% and on the Cutting Concentration in Annulus (CCA) method obtained values 4,822% - 4,907%. On the 8 Â½ â€ traject, the results of cutting removal with the Cutting Carrying Index (CCI) method were 4.852 - 14.492, the Cutting Transport Ration (CTR) method was 86.199% - 90.107% and the Cutting Concentration in Annulus (CCA) method was 4.708% - 4.782%. This research proves that the composition of mud determines the success of drilling activities so that the parameters of sludge to be used are very influential. Drilling parameters such as the rate of penetration (ROP) that are used are too high and too low pump flowrate will make the process of lifting the bad cutting which causes deposition of cutting so that both must be precisely determined to produce good hole cleaning.
