Core Flooding System

A core flooding system is a system that flows a fluid (gas or liquid) through a core sample at controlled conditions and measures flow parameters. Genesis produce versatile Core Flood Systems, these systems can be used for:

  • EOR tests and research Water flooding
  • Steady state permeability measurement
  • Relative permeability measurement(unsteady state method)
  • Flow distribution in multi-layered reservoirs
  • Formation damage tests
  • EOR tests and research
  • Acidization studies
  • Stimulation studies
  • Drilling mud invasion

Customized Flexibility

Because of the wide variety of tests that might be conducted in a core flooding system, Genesis systems are typically customized to meet the exact requirements for a specific application.
This brochure outlines options available for each component in the core flooding system to allow the user to specify the combination that will be best suited to their application.

Modular System Design

A core flooding system consists of several components which are combined into a single system CFS.
• Core holder(s)
• Pressure control system.
• Pumps system.
• Transfer vessel( s).
• Differential pressure measurement module( s)
• Back pressure control system.
• Mass flow controller (optional).
• Data acquisition

Core Holder(s)

Core holders is routinely used for gas and liquid permeability and other core flooding experiments. With this design, the core holder does not need to be completely disassembled in order to interchange core test samples. After the confining pressure has been released, the end lids and distribution plugs are removed and the core sample is easily removed from the sleeve. The sleeve and end caps remain in place within the core holder. Spacers are provided to accommodate undersized cores. The distribution plugs are provided with a double inlet and outlet. The volume of all ports and flow lines are kept to a minimum so that accurate flow data can be determined. Additional features are as follow:
• Single or dual core holders.
• Flow forward, reverse, parallel or in series.
• Placed at any angle to the horizon.
• Radial confining pressure.
• Range of core diameters (11/2" & 4").
• Core lengths up to 24".
• Multi-tap pressure ports along the core length can be added upon the request.

Pumps System

The PPA pumps have satisfied the requirements of many laboratory and scientific applications. These pumps were developed specifically for fluid delivery and fluid pressure control applications in core flow analysis. Moreover they operate in two modes, including constant rate and constant pressure. These pumps are used easily and the program is very user-friendly. The main features are as bellow:
• Volume: 250 cc or 500 cc Min rate: 0.001 cclmin
• Max rate: 35 cc/min
• Max Pressure: 6000 psi or 10000 psi (upon request)

Pressure Control System

Accurate pressure measurement is the key to calculate permeability and other flow parameter accurately. In order to measure inlet pressure, confining pressure and the required pressure of BPR, pressure transducers with accuracy of +/- 0.2% full scale are used. These pressure transducers are parallel connected to analog and digital gauges. Moreover to determine the differential pressure along the core and between ports on core holders (multi-tap pressure ports) accurately, a DP with accuracy of +/-0.04% full scale has been used. Selecting the optimum differential pressure transducer(s) depends on the differential pressure to be measured as well as the system pressure rating. Genesis engineers can help to select the optimum differential pressure transducers for a specific application.

Transfer Vessel(s)

The transfer vessels are used to transfer gas and liquid into system. These transfer vessels have a piston and injection fluid is placed above the piston and we can supply the pressure from below the piston by injecting the fluid with double displacement pump. Typical specifications:
• Pressure: 6000 psi, 10000 psi
• Temperature: up to 150°C
• Material: stainless steel 316 L
• Volume: 1000 cc, 1500 cc, 3500 cc


To provide the desired temperature, an oven is used to allow core flooding tests to be conducted at fixed temperature from room temperature up to 1500C. The inside chamber is made of stainless steel 304 and it is rectangular in shape with full toughened glass window to view in. Furthermore, they are easy in maintenance, durable, simple in use and cost efficient.NOTE: These ovens can also be customized as per the specifications detailed by our valued clients. Technical specifications
• Switches and indicating lamps are provided on front panel.
• PID controller
• 220 volts AC single phase.
• Outer body finished with powder coated paint finish
• High grade glass wool insulation between walls to avoid heat loss
• Programmable controller with 6 steps

Back Pressure Control System

In order to exert the reservoir pressure condition in core flooding experiments, a back pressure regulator is used. The BPR consists of two chambers separated by a piston with a needle connected to it on the lower side. The desired pressure (reservoir pressure) is applied to the upper chamber by a handle pump. The lower chamber meets the outlet pressure of system.
When the reservoir pressure is higher than the outlet pressure the needle seals off. Inversely when the outlet pressure exceeds the reservoir pressure the needle opens up and the excess fluid flows out. The aforementioned stages are continued until the user stops the system. The wetted part is stainless steel 316L and it withstands the pressure until 10000 psi.

Mass Flow Controller (MFC)

In some gas injection processes the determination of exact breakthrough time is vital and it is quantified by the volume of outlet gas. To measure and control the volume of outlet gas a MFC is used. To set the control mode and save the data, MFC is connected to data acquisition. The specifications of MFC are as follows:
• Max rate: 50 cc/min, 500 cc/min, 5000 cc/min
• Max pressure: 1500 psi
• Gas type: upon the request

Data Acquisition

Data is acquired automatically from each pressure and temperature transducers in the system by a PC-based data acquisition. This system allows the operator to specify which data is collected for a specific test as well as the data collection rate. The program is able to allow for functions such as individual control of automated valves, entry of transducer calibration values etc. This data acquisition and test control software is typically customized to each specific test system.


The POROPERM is an apparatus with automated permeameter and porosimeter used to determine properties of plug sized core samples at reservoir confining pressure. The gas permeability determination is based on the steady state method whereas the pore volume is determined using the Boyle’s law technique.

HB Pumps are manufactured and designed for applications that require accurate low rate. These pumps are used in larger scale flow applications and can pumps at constant rate as well as manintaining a constant pressure.These pumps were developed specifically for fluid delivery and fluid pressure control applications in core flow analysis. However, HB pumps have satisfied the requirement of many other laboratory and scientific applications. These pumps are also used in PVT applications where precision pulse-free flow or volume measurement are critical.
The different models of the HB pumps cover a wide range of pressure capabilities and flow rates. These pumps are supplied as either single cylinder pump or double cylinders pump, which deliver or receive a fluid for pressure control or in intermittent flow applications. A dual cylinder pump provides continousus pulse -free pumping.

Operational Simplicity

The HB pumps are very easy to operate. Pump-ISP is a user-friendly software package that provides complete control over any HB pump. The easy-to-use interface indicates the detailed status of each pump cylinder including its piston position and direction, valve positions, flow rate, pressure, cylinder volume and cumulative volume pumped.
Pumps are capable to deliver a specified volume of fluid. All measured information on the pump can be logged and easily exported for graphing and analysis.PPA Engineering also provides worldwide services for maintaining pump performance.
