“This guest lecture on ‘Materials in Oil and Gas Operation’ represents a concrete collaboration between academia and industry to provide practical and relevant insights for students. By bringing in experts from PT Tenaris and PT Future Pipe Industries, this event not only enriches students’ knowledge about material innovations in oil and gas operations but also strengthens their readiness to face industry challenges. At FTUI, we remain committed to creating inspiring and relevant learning environments that meet the needs of the times,” said Prof. Dr. Ir. Heri Hermansyah, S.T., M.Eng., IPU, Dean of the Faculty of Engineering, Universitas Indonesia.
In the first session, Syifa Rahmah presented an “Introduction to OCTG and Materials Selection.” OCTG, or Oil Country Tubular Goods, refers to steel pipes used in the oil and gas industry for various activities such as drilling, production, and well maintenance. These pipes are critical to ensuring safety, efficiency, and project success in the oil and gas industry.
Syifa explained several types of well loads, including axial loads, internal pressure, external pressure, and torque. She elaborated that axial loads stem from casing/tubing weight, thermal loads (expansion/contraction), hydrostatic buoyancy, friction, and bending in deviated or horizontal sections. Internal pressure arises from fluid pressure, thermal expansion, and well-stimulation. External pressure includes fluid pressure, geomechanics, and thermal expansion. Lastly, torque results from rotational applications such as drilling with casing, under-reaming, or rotation during cementing.
Syifa also described the manufacturing process for casing and tubing at Tenaris, showcasing the company’s Heat Treatment Facility and various testing procedures conducted there. She concluded her session by highlighting Tenaris’s flagship products.
In the second session, Nico Riyanto discussed GRE Composite Pipes, focusing on the materials used in FPI’s pipe production and their advantages. According to Nico, GRE pipes have a more streamlined production process than metal pipes, requiring only three months compared to six months for metal pipes. Additionally, GRE pipes are easier to install and involve lower safety risks.
Nico further explained that GRE pipes offer lower operational costs due to their reduced maintenance requirements and longer lifespan. He also elaborated on the GRE pipe manufacturing process at FPI, joint systems, product qualification, and field applications.
The event continued with a Q&A session and a quiz for undergraduate students from the Metallurgical and Materials Engineering program at FTUI. It concluded with prizes awarded to quiz winners and tokens of appreciation presented to the guest speakers.
