The Apex Petroleum Services three-phase horizontal well testing separator is designed to separate and measure the gas, oil, and water produced from a well. This separator can be used in well testing and to clean up new completions or stimulated wells.
The horizontal test separator is a self-contained unit with the valves and pneumatic controls needed to regulate the pressure and fluid levels. The redundant safety design incorporates a pre-set relief valve and rupture disc.
The new Apex horizontal test separator has several improvements over previous models. It now has box beam skids for durability, removable pull bars, and revised lift fittings with ISO corners. Also, less welding is required to fabricate the manifold. The positioning of equipment has been revised to maintain the ISO specifications, and the rupture disc is now run horizontally. High-level alarms and automatic shutdowns eliminate liquids spilling over into the gas flare and gas blow-by to surge tank.
