New GLCC field applications designed utilizing the TUSTP GLCC simulator, have been installed by Caltex Pacific Indonesia (CPI) in the Light Oil Steam Flooded (LOSF) project in Minas, Indonesia. The project was executed by Drs. Jack Marrelli from Texaco and Gene Kouba from Chevron. The largest GLCC (60 in.-ID) for bulk separation/metering and three 36-in. ID metering GLCCs for well test metering applications have been recently installed. The bulk separation/metering GLCC 5 ft ID and 20 ft tall is shown in Figure 2. The GLCC operates at 170 psia and 3600F, handling liquid and gas production rates of 180,000 bpd and 71 MMscfd, respectively. The GLCC is equipped with control valves on the gas and liquid legs and a sophisticated control system for liquid level control. TUSTP personnel were closely involved in designing these GLCCs and the respective control systems. The 36-inch diameter well testing GLCC operates at 170 psi and 3600F, handling liquid and gas production rates up to 7000 BBl/d and 4.5 MMscfd, respectively. The control philosophy for this GLCC was also developed by TUSTP.
