This document provides an overview of upstream oil and gas production facilities, including field surface facilities, field production facilities, and central processing facilities. It describes the key components and functions of these facilities. These include wellheads, pumps, manifolds, separators, compressors, heat exchangers, dehydrators, meters, tanks, flares, and control systems. Power is generated onsite and distributed to run the various equipment used in processing raw production into marketable products and disposing of byproducts.

- 10. OIL GATHERING MANIFOLD(OGM) It serves two purposes: I. To collect production from several individual wells and direct it via a production manifold to a gathering line, a gathering station, or a field pump station II. To direct production via a test header from a selected well to a well test skid located at each manifold Located adjacent to a producing well
- 11. SEPERATORS Mechanical deviceswhere gas is flashed from the liquids and “free water” is separated from the oil Can be either horizontal, vertical and spherical in configuration Two types Production separator and Test separator Production separator can be either two phase and three phase Most oil contracts specify a maximum percent of basic sediment and water (BS&W) that can be in the crude Typically vary from 0.5% to 3% depending on location Water from the separators must be treated to remove small quantities of produced oil
