PRODUCTION FACILITY
INTRODUCTION
Separate the well stream into three components, called
“phases” (oil, gas, and water) Process these phases into some marketable products Dispose of them in an environmentally acceptable Accommodation of accurate measuring and sampling of
the crude oil.

Wellhead
WELLHEAD
Maintains surface control using choke Prevent well fluids from leaking or blowing at the surface Design to withstand pressures of up to 140 MPa(1400 Consist of three components;
I.Casing headII.Tubing headIII.Christmas Tree
Consist of two types of Pumps 1.Electric Submersible Pumps (ESP)2.Progressive Cavity Pumps (PCP)
WELLHEAD
ELECTRIC SUBMERSIBLE PUMPS Electrically driven and submersible Consist of three units
I. Electric Motor
II. Protector
III.Multistage Centrifugal Pump
Operation is controlled by a control box
PROGRESSIVE CAVITY PUMPS

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
SEPERATORS Mechanical devices where 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
SEPERATORS
STAGING OF SEPARATORS
TWO PHASE SEPERATORS
THREE PHASE SEPERATORS
COMPRESSOR
Consist of I. Scrubbers- remove liquid droplets
II. Heat Exchangers
HEAT EXCHANGERS
Use to cool the gas
HEAT EXCHANGERS
DEHYDRATOR/DESALTER
Dehydration Desalting Consists of three primary steps
I. Injection of wash water
II. Contact between the wash water and the soluble salts, and
III. Separation of the aqueous phase – most of the
installed hardware is involved in the phase

FLARE SUBSYSTEM
Include Flare, atmospheric ventilation and blow down Provide safe discharge and disposal of gases and liquids
resulting from:I. Spill-off flaring from the product stabilization system (Oil, Condensate etc.)I. Production testing II. Relief of excess pressure caused by process upset conditions and thermal expansionI. Depressurization either in response to an emergency situation or as part of a normal procedureI. Planned depressurization of subsea production flowlines and export pipelines.

CONTROL SYSTEM
Programmable Logic Design (PLCs) and Distributed Control System (DCS)
Provide automatic day-to –day control of oil field production system
CONTROL SYSTEM
POWER GENERATION AND DISTRIBUTION
Provided from main power or from local diesel generator sets
Large facilities have great power demands, from 30 MW and upwards to several hundred MW.
Voltage levels for High, Medium and Low voltage distribution boards are 13- 130kV, 2-8 kV
and 300-600 V respectivelyPower is generated and exchanged with mains or
other facilities on the HV distribution boardRelays for protection functions
POWER GENERATION AND POWER GENERATION AND DISTRIBUTIONDISTRIBUTION
POWER GENERATION AND DISTRIBUTION
Power management system is used for control of electrical switchgear and equipment
Includes HV, MV and LV low voltage switchgear Motor Control Centers (MCC) and emergency generator sets
