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

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)

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

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

COMPRESSOR

Consist of I. Scrubbers- remove liquid droplets

II. Heat Exchangers

HEAT EXCHANGERS

Use to cool the gas

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.

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 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
