Abstract

Kemampuan lumpur pemboran dalam mengangkat cutting perlu diperhatikan, hal ini untuk meminimalisir terjadinya masalah pemboran yaitu terjepitnya rangkaian pemboran yang dikarenakan oleh adanya cutting yang menumpuk pada rangkaian alat pemboran. Salah satu parameter penting yang perlu diperhatikan pada lumpur pemboran dalam proses pengangkatan cutting adalah Lifting Capacity. Pada penelitian ini untuk mendapatkan Lifing Capacity dilakukan perhitungan kecepatan lumpur pemboran di Annulus dan kecepatan turun cutting pemboran. Dari hasil perhitungan kecepatan lumpur pemboran dan kecepatan turun cutting didapatkan bahwa kecepatan lumpur pemboran lebih besar dari kecepatan (slip) turun cutting, hal ini menunjukkan bahwa fluida lumpur pemboran berhasil mengangkat cutting pemboran. Keberhasilan proses pengangkatan cutting didukung dengan hasil yang didapat dari nilai Lifting Capacity dengan tingkat keberhasilan menunjukkan prosentase sebesar 91% sampai 92.346%. Hasil dari tingkat keberhasilan yang tinggi ini dipengaruhi oleh beberapa faktor yaitu, densitas dari fluida pemboran, viskositas fluida pemboran, tipe aliran fluida, ukuran lubang anulus, kecepatan pada lubang anulus, serta bentuk dan ukuran cutting.

Abstract

The aims of this study were to (1) analyze the differences in student learning motivation using the SAVI learning model and those using the expository learning model, (2) to analyze the differences in student learning motivation using the SAVI learning model and those using the expository learning model in terms of school majors. This study is an experimental study using a Mix Method approach involving 68 students of the Akamigas Balongan Indramayu Petroleum Engineering Study Program. The sampling technique used was Simple Random Sampling, two classes were selected as samples, namely class 20 TPA as experimental class I and class 20 TPB as experimental class II. The tools or instruments in this study were learning outcomes tests in the form of explanations about explanations, interviews, motivation questionnaires and questionnaires from school majors. The data analysis of this research is using the mean comparison test, ANOVA test and correlation test. The results of this study are: (1) the learning motivation of students who use the SAVI learning model is better than those using the expository learning model, (2) the learning motivation of students who use the SAVI model and come from the origin of the science department is better. Thus, the SAVI learning model is good for use in learning mathematics because students are more active and interested in learning and can be a reference for teachers/lecturers in increasing students learning motivation.

Abstract

Abstrak : Lapangan ini berada pada Cekungan Bonaparte Utara, wilayah pengembangan bersama antara pemerinta Timor-Leste dengan Pemerintah Australia di perairan laut timor. Formasi yang umum di jumpai pada Cekungan Bonaparte utara sebagai reservoar yaitu Formasi Plover dengan litologi batu pasir yang berumur Jurasik.Analisis petrofisik reservoar Formasi Plover Cekungan Bonaparte Utara lapangan “X” di daerah penelitian ,peneliti mengunakan tiga sumur dan tiga (3) horizon yaitu formasi Plover , formasi echuca shoal dan formasi cope londondary serta seismik 2D terdiri dari 7 lines seismik.Hasil interpertasi petrofisika berdasarkan cut-off pada A1 didapatkan harga porositas sebesar 12%, saturasi air sebesar 60%, dan V-shale sebesar 9,4%. Sedangkan pada sumur A8 nilai porositas sebesar 8,4%, nilai saturasi air 47,5% dan nilai V-shale 9,4%. Sedangkan pada sumur A14 nilai porositas sebesar 11,3%, nilai saturasi air 32,6% dan nilai V-shale 2,7%.Kegiatan perhitungan cadangan hidrokarbon dilakukan setelah proseses interpretasi geologi bawah permukaan telah selesai.sehinga dapat diketakui kuantitas dari minyak dan gas bumi yang ada pada daerah penelitian .Hasil perhitungan cadangan hidrokarbon diperoleh peta permukaan meliputi ,Top Structure , Peta Net To Gross ,Peta Overlay Peta Top Structure Lowest Know Gas. Berdasarkan hasil perhitungan mengunakan metode volumetric pada plover formation diperoleh nilai Original gas in place(OGIP) Sebesar 11,029,834 SCF.
