Abstract

The problem in Indonesia, especially for piping problems are generally caused by blockages that interfere with the flow process, these blockages are formed due to the presence of scales or minerals deposited to the pipe wall. Scale formation is due to the alteration of the physical properties of the oil including pour point, viscosity or others. Many technological breakthroughs developed to overcome this problem are with the addition of hot water, the injection of chemical fluids dispersant into crude oil, which serves to lower the pour point of the crude oil that will be in production or use surfactant as inhibitors so that the inner pipe wall will be water wet which can prevent the occurrence of wax deposition on the pipe surface. In subsequent developments the researchers will review by replacing or adding pipe materials with certain materials that are able to inhibit the processing of wax deposits in the pipe walls. By classifying and identifying materials that are able to inhibit the formation of wax on the pipe, it is expected to estimate the design of the pipe string so as not to form wax deposits, such as predicting wax formed at the distance So that the material application can be optimal. Verification of data on tubing will result in supporting data for the determination of the crude oil flow rate with an Excel plot used to determine the rate of wax deposition in tubing. With some selected material is expected researchers are able to determine the best material to handle the problem of wax deposits.

Abstract

Ketika temperatur crude oil berkurang, komponen-komponen berat seperti paraffin/wax (C18 – C60) akan terpresipitasi dan mengendap pada dinding pipa. Pengendapan wax dapat menyebabkan diameter internal pipa berkurang dan pipa tersumbat. Laju produksi yang rendah dapat mempengaruhi terjadinya deposit wax karena waktu tinggal (residence time) minyak yang lama di pipa. Residence time minyak yang lama, menyebabkan adanya heat loss dari fluida, sehingga menurunkan temperatur minyak saat mengalir. Penelitian ini dilakukan dengan tujuan untuk memprediksi kedalaman terbentuknya wax pada sumur X. Untuk mengetahui kedalaman terbentuknya wax pada sumur X, yaitu dengan memplot hasil prediksi distribusi tekanan dan temperatur per kedalaman kedalam kurva wax deposition envelope. Fase wax pada sumur X akan muncul pada temperatur 131 °F dan tekanan 343 psi di kedalaman 300 ft dari kepala sumur dan pada saat tekanan statis reservoir mencapai 1752 psi.

Abstract

MPD (Managed Pressure Drilling) has been used worldwide to overcome drilling challenges in onshore and offshore operations. MPD has proven to save significant cost efficiency in every applications, by reducing NPT (Non Productive Time) caused by drilling problems such as, severe loss circulations, loss-kick cycle, and well control events. Indonesia is one of major country in Asia Pacific that has several needs to developing or exploring new opportunities with drilling challenges, especially in vuggular carbonate reservoirs, narrow drilling windows, and wellbore in-stability. This paper will present the basic theory on MPD, MPD equipment’s, types of MPD, and elaborate more on successful MPD operation in onshore Indonesia, and clustering the solutions of drilling challenges.
