“…Karena aliran slug sangat kompleks dan tidak stabil, sulit untuk memprediksi penurunan tekanan. Selain itu, sifat aliran akan bervariasi tergantung pada apakah pipa itu horizontal, vertikal, atau miring (Darmawan & Prasetyo, 2022).…”

Penelitian yang dilakukan adalah mengetahui pengaruh pola aliran terhadap pressure loss yang terjadi pada pipa vertikal dan mengetahui pengaruh viskositas minyak terhadap pressure loss dan pola aliran pada GOR rendah dengan membuat visualisasi aliran fluida di dalam pipa vertikal menggunakan software Ansys Fluent. Prosedur penelitian diawali dengan pembuatan geometri pipa vertikal sepanjang 100 in (2.54 m) dan ber-diamater 6.5 in dengan inlet berada di bagian bawah dan outlet berada di bagian atas. Sensitivitas yang digunakan untuk mengetahui perbedaan pola aliran dan pressure loss yaitu dengan membuat variasi kecepatan dan viskositas fluida minyak dan gas ketika mengalir di dalam pipa vertikal. Dibuat variasi kecepatan minyak dan gas dari kondisi 1 sampai 16. Dari berbagai kondisi tersebut dihasilkan pola aliran Bubble Flow, Slug Flow, Churn Flow, dan Annular Flow. Kemudian dibuat sensitivitas pada viskositas minyak untuk mengetahui pola aliran dan pressure loss yang terjadi di dalam pipa vertikal dengan GOR 3.7362 SCF/STB. Viskositas minyak yang digunakan yaitu 10 cP, 100 cP, 1000 cP, 2000 cP, dan 3000 cP. Dari kelima kondisi tersebut didapatkan pola aliran didalam pipa vertikal yaitu Slug Flow. Kemudian pada penelitian ini akan ditarik data static pressure pada saat waktu 3 detik fluida mengalir di dalam pipa dari setiap kondisi untuk di bandingkan. Berdasarkan hasil simulasi pola aliran dan penarikan data static pressure, terjadi pressure loss yang tinggi di awal ketika fluida gas dominan memasuki pipa vertikal dan fluida gas yang masuk ke dalam pipa vertikal akan menunjukkan kurva static pressure yang konstan.

“…This set-up makes allowance for circulations through the MPD manifold and circulations by conventional methods [35]. The RCD is not considered as a well barrier as regards well control operations [38]. In floating drilling rigs, the RCD is installed below the slip joint with flow diverted through flexible lines to the return system.…”

“…The automated choke manifold is run on control systems with a programmable logic controller which could be set to control the valve percentage opening and closing. In addition, the automated choke manifold is connected to auxiliary mud or nitrogen pump to provide the surface back pressure (SBP), as well as monitor flow rates in and out of the wellbore [38]. MPD systems also includes a backpressure pump, flowmeter, and software algorithm.…”

The devastating impact of the Macondo blowout incident has underscored the need for effective well barriers, early kick detection systems, and increased automation of well-control operations toward successful drilling and completion operations particularly in deep offshore environments. Early kick detection systems should be capable of detecting a gas influx both during drilling and tripping operations regardless of the drilling fluid system with minimal false-negative alarms, while automated control systems regain well-control eliminating delays or omissions due to human error. In this chapter, developments in the deployment of early kick detection and automated control systems in conventional and managed pressure drilling operations are reviewed. We discuss the use and placement of surface sensors such as the Coriolis flowmeter, smart flowback fingerprinting when the rig pumps are off, real-time gas monitoring along the marine riser and downhole measurements complimented with machine learning algorithms for early kick detection. We then focus on the application of automated well-control systems for managed pressure drilling operations for which gas kicks are circulated without stopping the pumps or shutting in the well and in conventional well operations requiring intelligent tool joint space-out prior to well shut in especially for deep offshore operations.
