the effect of drill pipe rotation on improving hole cleaning using polypropylene beads in water based mud at different hole angles
Journal of Petroleum Exploration and Production Technology, 2020Co-Authors: A. Katende, B. Segar, I. Ismail, F. Sagala, H. H. A. R. Saadiah, A. SamsuriAbstract:Hole cleaning is always a problem, particularly during drilling operations, and drilling fluid plays an important role in Transporting drill Cuttings through an annular section of wellbore to the surface. To Transport the Cuttings, a water-based mud with added polypropylene beads was selected since it is environmentally friendly and cost efficient. The polypropylene beads help to Transport Cuttings by providing an additional buoyancy force that lifts the Cuttings to the surface via the influence of collision and drag forces. This experiment was performed using a 20 ft test section, 10 ppg drilling mud and 0.86 m/s annular velocity in a laboratory scale rig simulator, and the concentration of polypropylene beads was varied from 0 to 8 ppb. As the concentration of polypropylene increases, the Cutting Transport ratio also increases. It was observed that the fewest Cuttings are lifted at a critical angle of 60°, followed by 45°, 30°, 90° and 0°. Additionally, Cutting sizes had moderate effects on the Cutting lifting efficiency, where smaller Cutting sizes (0.5–1.0 mm) are easier to lift than larger Cutting sizes (2.0–2.8 mm). Furthermore, a study of buoyancy force and impulsive force was conducted to investigate the Cutting lifting efficiencies of various concentrations of polypropylene beads. This lifting capacity was also assisted by the presence of polyanionic cellulose (PAC), which increases the mud carrying capacity and is effective for smaller Cuttings. The results show that in the presence of pipe rotation, the Cutting lifting efficiency is slightly enhanced due to the orbital motion provided by the drill pipe for better hole cleaning. In conclusion, polypropylene beads combined with pipe rotation increase the Cutting Transport ratio in the wellbore.

Experimental investigation of the effect of drill pipe rotation on improving hole cleaning using water-based mud enriched with polypropylene beads in vertical and horizontal wellbores
Journal of Petroleum Science and Engineering, 2019Co-Authors: Nursyafiqah S. Heshamudin, A. Katende, I. Ismail, F. Sagala, Halimatun A. Rashid, A. SamsuriAbstract:Abstract Field experience has shown that the inefficient Transport of small Cuttings is a main factor contributing to excessive drag and torque during the drilling of a deviated hole; however, very little is known about the Transport behavior of small Cuttings. This experimental study investigates the effect of different polypropylene bead concentrations in water-based mud (WBM) on hole cleaning, along with the effects of Cutting size, drill pipe rotation, and hole inclination angle. A total of 160 runs were performed using an experimental rig consisting of a 13 ft (3.96 m) long casing with a 2 in (50.8 mm) Inner Diameter (ID) and a rotary inner pipe with a 0.8 in (20 mm) Outer Diameter (OD). Four Cutting size ranges, namely, 0.5–1.0 mm, 1.0–1.4 mm, 1.4–1.7 mm, and 1.7–2.0 mm, with a density of 2400 kg/ m 3 were tested in WBM with varying polypropylene bead concentrations ranging from 0 to 8 ppb. The concentric annulus flow test section was changed to vertical and horizontal angles with pipe rotation from 0 to 150 rpm. The mud density and viscosity were maintained at 10 ppg and 16 cp, respectively, under a flow velocity of 3.48 m/s (Reynolds number of 6620). The results indicate that smaller Cuttings are easier to Transport at all pipe rotations and polypropylene bead concentrations in both vertical and horizontal holes. The optimal pipe rotational speed was found to be 60 rpm. In this study, polypropylene beads undeniably enhanced the mud carrying capacity by significantly increasing the Cutting Transport ratio (CTR) by up to 16.57% in vertical holes and 15.73% in horizontal holes.

EVALUASI PENYEBAB PIPA TERJEPIT SERTA PENANGANANNYA PADA TRAYEK 17 ½” SUMUR “RP”LAPANGAN “Y” PT PERTAMINA EP
2016Co-Authors: Risky PraptomoAbstract:Operasi pemboran yang dilakukan tidak selalu berjalan dengan lancar seperti yang diharapkan. Adakalanya terjadi masalah -masalah yang mengganggu operasi pemboran dan sangat merugikan. Secara terinci kerugian-kerugian ini meliputi kerugian terhadap waktu, peralatan, dan biaya operasi pemboran.Salah satu masalah dalam operasi pemboran berarah (Directional Drilling) sumur RPlapangan Y PT Pertamina EP adalah pipa terjepit (stuck pipe), yang maksudnya adalah pipa tidak dapat digerakkan di dalam lubang (tidak dapat diputar dan diangkat) dan adakalanya dapat diputar namun tidak dapat diangkat. Akibat dari terjepitnya pipa pemboran ini adalah terhambatnya operasi pemboran. Metodologiyang digunakandalamSkripsiiniadalah,pengumpulan data,dan kemudiandilakukanevaluasipenyebabpipa terjepit.Evaluasi penyebab terjadinya pipa terjepit dikaji berdasarkan beberapa aspek yaitu: Aspek lithologi batuan, Aspek geometri lubang bor apabila nilai dogleg survey melebihi dogleg severity akan menyebabkan key seat, Aspek susunan rangkaian pemboran yang digunakan, Aspek lumpur pemboran apabila besarnya harga differential pressure pada kedalaman titik jepit sebesar kurang dari 200 psi maka sesuai dengan batas aman yang direkomendasikan. Perhitungan pengangkatan Cutting dikatakan optimum apabila parameter Cutting Transport Ratio (Ft) lebih dari 90%, Cutting Concentration (Ca) kurang dari 5% dan Particle Bed Index (PBI) sama dengan atau lebih dari 1. Besarnya differential pressure pada kedalaman titik jepit sebesar 87.95 psi masih sesuai dengan batas aman yang direkomendasikan yaitu kurang dari 200 psi. Hasil perhitungan pengangkatan Cutting pada trayek 17 ½” tidak optimum dengan harga Ft sebesar 86.13 % dan PBI sebesar 1. Dari aspek geometri lubang bor diketahui perhitungan dogleg survey melebihi dogleg severity dan menandakan adanya keyseat , jadi dapat disimpulkan bahwa penyebab terjadinya pipa terjepit dikarenakan terjadinya key seat.

2017Co-Authors: Roberto Hutama SumantriAbstract:ABSTRAK Operasi pemboran yang dilakukan tidak selalu berjalan dengan lancar seperti yang diharapkan. Adakalanya terjadi masalah-masalah yang mengganggu operasi pemboran dan sangat merugikan. Secara terinci kerugian-kerugian ini meliputi kerugian terhadap waktu, peralatan, dan biaya operasi pemboran.Salah satu masalah dalam operasi pemboran berarah sumur X lapangan Y adalah pipa terjepit, yang maksudnya adalah pipa tidak dapat digerakkan di dalam lubang (tidak dapat diputar dan diangkat) dan adakalanya dapat diputar namun tidak dapat diangkat. Akibat dari terjepitnya pipa pemboran ini adalah terhambatnya operasi pemboran. Metodologi yang digunakan dalam Skripsi ini adalah, pengumpulan data, dan dilakukan analisa penyebab pipa terjepit. Analisa penyebab terjadinya pipa terjepit dikaji berdasarkan beberapa aspek yaitu: Aspek lithologi batuan, Aspek geometri lubang bor apabila nilai dogleg survey melebihi dogleg severity akan menyebabkan key seat, Aspek susunan rangkaian pemboran yang digunakan, Aspek lumpur pemboran apabila besarnya harga differential pressure pada kedalaman titik jepit sebesar antara 100 – 200 psi maka sesuai dengan batas aman yang direkomendasikan. Perhitungan pengangkatan Cutting dikatakan optimum apabila parameter Cutting Transport Ratio (Ft) lebih dari 90% (Bourgoyne AT,1986), Cutting Concentration (Ca) kurang dari 5%(Millpark,1992) dan Particle Bed Index (PBI) sama dengan atau lebih dari 1 (Ziedler,1988). Besarnya differential pressure pada kedalaman titik jepit sebesar 87.95 psi dinilai terlalu rendah karena kurang dari batas aman yang direkomendasikan yaitu antara 100 - 200 psi, sehingga disarankan untuk menaikan densitas lumpur sebesar 10,61 ppg. Hasil perhitungan pengangkatan Cutting pada trayek 17 ½” tidak optimum dengan harga Ft sebesar 86.13 % dan PBI sebesar 1. Dari aspek geometri lubang bor didapatkan hasil dogleg survey sebesar 1,04 dimana melebihi dogleg severity yang diperbolehkan yaitu 0,2. Jadi dapat disimpulkan bahwa penyebab terjadinya pipa terjepit dikarenakan terjadinya key seat. Kata kunci: Pipa Terjepit, Key seat, Dogleg severity
