IPS UNIPORT Students Tour of BOG

Twenty Post Graduate Diploma in Petroleum Technology (PGDPT) students of the Institute of Petroleum Studies (IPS), University of Port-Harcourt, were on a one day Field Trip to our facility on Thursday, 26th October 2017. The purpose of the visit was to expose the students to BOG business offerings and how those offerings relate with their courses in general. In particular, it was to avail the students with practical/hands-on learning of Multi Phase Flow Meter (MPFM) skids and a demo of how they work.

Well Testing Unit

During the tour, the students had the opportunity to see the Haimo MPFM and its uses in Well Testing campaigns. The students interacted with the operators of the MPFM; they physically examined it and were made to understand how it works. This was a good opportunity for them because the MPFM is not commonly found in Nigeria.

They were taken round and shown all the equipment needed in a Well Testing rig up process and the actual well testing using the MPFM. Among the equipment they saw were:

The process flow of a reservoir effluent during well testing activity using the MPFM was explained to the students, just as the operating principles of the BOG/HAIMO MPFM were detailed; the Venturi measures the mass flow rate; the single gamma 1 & 2 measures the Gas Volume Fraction (GVF) while the dual gamma measures the WLR.

Haimo multiphase meter uses Americium 241 (59.5Kev) with half-life of 433 years. The meter uses a scintillating detector that works with the sources in measuring the density of each phase fraction. The measurement principle is dependent on the ability of each phase to attenuate gamma rays. The mass attenuation is subject to the type of elements that the phase (Oil, Gas or Water) is made of and the energy level of the gamma rays passing through.

The functions of the by-pass manifold was also explained to the students;  it isolates the meter while carrying offline calibration prior to preliminary and the actual test. The choke manifold controls the well pressure through the various choke beans. The configuration of the Haimo MPFM choke manifold is that of 3 inches 10,000psi RF-Cameron type gate valve. It has fixed and adjustable choke boxes. The need for a choke manifold or choke box in any well, be it exploratory wells or production wells, cannot be overstated because it helps in protecting the lifespan of the well.

Composite Pipes Unit

At the Composite Pipe Systems Unit, the students were introduced to different types of the NOV composite pipe products, their chemical compositions and applications.

The students were made to understand that Glass Fibre Re-inforced Epoxy (GRE) pipe system is an alternative solution to the conventional steel pipes that are vulnerable to corrosion.

In the Spooling Workshop, the students were shown how the Bomax machine works. The machine is used for cutting pipes of various diameters to precision. They were also shown the different pipe shavers on display and were told their various functions. Pipe shavers are used for surface preparation (shaving of Spigot) on cut spool ends prior to bonding.

They also sighted the chemical storage container used to ensure that the chemicals stored in it do not drop below or exceed the required storage temperature. The vacuum unit was shown to the team as well. It is used to extract fibre dust from the fabrication workshop to the collection point through flexible hoses.

In addition, the students were exposed to the air compressor unit. The compressor is used to pressurize finished spools during hydrotest. Hydrotest is conducted to ascertain the integrity of the spool. The students also had the opportunity to see numerous sizes of pipes and pre-fabricated spools.

Hydraulics Unit

At the Hydraulics Unit, the students were exposed to how the Unit assembles hoses of different types for different applications by way of crimping/swaging fittings/couplings on them based on client’s specification. The crimped hoses are pressure-tested to ascertain the integrity of the hoses before delivering them to client’s site. The parameters hydraulic engineers get when they go to client facilities for hose measurement or hose survey were also highlighted to the students.

Rotating Equipment Unit

At the BOG Rotating Equipment Service Centre, the students were exposed to Rotating Equipment products and services.  Some of these include: Sundyne pumps, Ingersoll Rand Air Compressors, Milton Roy Metering Pumps and BOG Dosing skid. They were also exposed to workshop equipment and tools.

Sundyne Pumps were shown to the students. These pumps are used for transferring fluid from a low-pressure side to a high-pressure side and can handle fluid in liquid and gaseous states. They are used in LNG plants, hydrocarbon processing plants, petro-chemical plants, fertilizer processing plants and refineries.

Ingersoll Rand Air Compressors are used to deliver compressed air. They may be engine driven or electric motor driven, depending on application and working environment. The different categories of these compressors were shown to the students.

Another type of compressors shown to the students are the Rotary Screw Compressors which are used to supply instrument air and hydro-test applications. They are found in food processing plants, breweries and in the civil/mining industry.

Milton Roy Metering Pumps were also shown to the students. They are used majorly for dosing and metering applications because they can produce a calculated amount of fluid in a process line. They are used in chemical/petrochemical plants, water treatment plants, pharmaceutical industry, power and gas plants.

The student had the opportunity to see so many Workshop Equipment at the Rotating Equipment Service Centre. Some of these include: gearbox overhaul stand, dry ice freezer, Durocell Ovens, Mobile high pressure washing machine, steam washing machine, overhead crane, pipe rack, work benches, table vices, BOG Milton Roy dosing skid and a 10-ton hydraulic press.

Overall, BOG demonstrated its commitment to giving back to the society by accepting to have the students at our facilities in Port-Harcourt and the demonstrations that were done were value-adding to the students.

BOG Senior Field Service Engineer – Hydraulics, Coleman Okonkwo, explaining the functions of Hydraulic Equipment in hose fabrication.


Sylvester Ogheneochuko, Field Service Engineer – Rotating Equipment, explaining to the students how Sundyne HMD KONTRO centrifugal pump operation is done.


Sylvester Ogheneochuko, Field Service Engineer – Rotating Equipment, explaining how T30 IR air compressor operates to the UNIPORT students on their internship programme.


John Ossia, Well Test Operator and Obinna Odum, Operations Manager, explaining to the students the functions of the by-pass manifold. The bypass manifold helps to isolate the Multi Phase Flow Meter (MPFM) when carrying out offline calibration on the meter prior to testing.


John Ossia, Well Test Operator, explaining the operating principle of the dual gamma meter in measuring the water cut. The dual gamma measurement is key because it determines the accuracy of the net oil measurement on any well being tested.


John Ossia, Well Test Operator explaining the operating principle of the Haimo meter on the 4” single gamma leg. The operating principle on that 4” leg is that the venturing measure the mass flow on the conduit without separation.
