Christmas Tree
 The PCP Christmas tree assembly
comprises of Master valve, BOP, kill
wing valve and Drive head on top.
 At the bottom we have tubing hanger
which has got chemical injection
connection and down hole gauge cable
running up to the downhole.
 The wing XSV is installed for the slam
shut of the flow arm in case of trip
scenario.

PCP (Progressive Cavity Pump)
PCP: A Progressive cavity pump is a type of positive displacement pump
and is also known as a progressing cavity pump, eccentric screw
pump or cavity pump.
PC Pumping Systems typically consist of the following components:
 Surface Equipment
Drive head assembly
VFD (Variable Frequency Drive)
Down hole gauge Panel (Geophysical Research Company)
BOP (Blow Out Preventer), Flow Tee – Kombi Tree
 Down hole equipment
Stator (Stationary with tubing)
Rotor (Internal & Rotary with drive rods)

Polish Rod and Clamp arrangement
 The entire series of Polish rod,
Sucker rod and Rotor is
suspended in the downhole
through the Polish rod clamp.
 Sucker rods transfers the power
from the prime mover ( Motor )
to Rotor.

PC Pumping System
PCP Systems typically consist of a surface drive, a sucker
rod string, a production tubing string and, of course, the
downhole Progressing Cavity Pump.
The pump comprises two key elements:
A single helical-shaped ROTOR that turns inside a double
helical elastomer-lined STATOR
In most cases, the stator is attached to the bottom of a
production tubing string and the rotor is attached to a
drive string that is suspended and rotated by the surface
drive.

Progressing Cavity Pump
General Features
 Classified as a single rotor, internal helical gear,
positive displacement pump
 Consists in two key components:
 Rotor:
 Is a high strength steel component externally
machined as a helix of “n” lobes and coated with
chrome or an alternative hard material.
 Only moving part.
 Stator:
 Generally made with elastomer (or rubber) with
and internal shape as an helix of “n+1” lobes.
This rubber body is bonded to the interior of a
steel tube.
 Stationary piece.

VFD & GRC Panel
 VFD , variable frequency drive is a
device which is used to control the
speed by adjusting frequency of the
motor input power supply.
 The LCD screen display’s the
parameters related to Motor i.e.
frequency, current, avg voltage etc.
 The Down hole gauge (GRC) panel is
installed to monitor the well downhole
parameters like Pump intake/discharge
temperature & Pressure locally.

Kombi-Tee Functions
 Provides a solid platform to mount
the PCP Drivehead
 Side ports direct the well
production down the flow line
 BOP seals off wellbore to allow
servicing of the surface equipment
 Polish Rod Clamp suspends the rod
string and resists torque, allowing
for safe maintenance and easier
removal and installation of the
Drivehead
 By applying 500 ft-lbs of torque to
the lock out rams, they will
suspend ≥39000 lbs of axial load and
resist ≥1000 ft-lbs of torque

Jet Pumps
• The actual working components of the jet pump are the nozzle,
throat and diffuser.
• These components are assembled in a variety of configurations
and materials to suit the production requirements and downhole
environment.
How the Jet Pump Works
• Power fluid at high pressure (low velocity) is converted to a low-
pressure (high velocity) jet by the nozzle.
• The pressure at the entrance of the throat becomes lower as
the power fluid rate is increased. Due to this lower pressure,
fluid is drawn in from the wellbore.
• The suction fluid becomes entrained with the high velocity jet
and the pumping action then begins.
• After mixing in the throat, the combined power fluid and suction
fluid is slowed down by the diffuser. Because the velocity is
reduced, the pressure increases – rising to a value sufficient to
pump the fluid to the surface.
A full range of nozzle and throat sizes are available to allow power
fluid rate and pressure to be varied to meet various requirements.
