PROPOSAL FOR TRAINING

STRUCTURAL UNCERTAINTY ASSESSMENT:

FAULT CONNECTIVITY AND RESERVOIR COMPARTMENTALISATION

Structural evaluation of petroleum prospect, uncertainty assessment during field development and later reservoir compartmentalisation studies for assets optimisation are carried out by only few companies and regulating authorities in the oil and gas industry.  After initial structural studies leading to discovery and field development, there is need for structural assessment at field scale during the life of the project.  Fault connectivity studies ensure that well placement (injectors and producers) are aligned across reservoir compartments, thereby optimising development and saving costs.

Understanding vertical and lateral reservoir compartmentalisation requires an in-depth fault connectivity analyses. Results of throw mapping, horizon top and base summation, Shale Gouge Ratio (SGR) and other fault assessment tools (including 4D, material balance and well testing / interference results, where available) would be helpful before, during and after drilling wells.  It is useful for modelling, both in terms of STOIP computation and dynamic modelling.

Connectivity studies also evaluate abnormal pressures, underpressure and overpressures, depletion and impact on well completion as well as targeting infill wells for unswept hydrocarbon. Several modules are covered in Fault characterisation and connectivity assessment training, some of which are:

  • Hydrocarbon Retention
  • Sealing Processes
  • Efficiency and Integrity of Seals
  • Indication of Seal Breaching
  • Types of Seals
  • Vertical Lithological Seal
  • Stress Seals
  • The Pressure Seal
  • Lateral Fault Seal
  • Seal and Hydrocarbon Column Height
  • Evaluation of Sealing and Leaking Faults
  • Throw Mapping
  • Shale Gauge Ratio – SGR
  • Field Study of Fault Sealing
  • Laboratory Study on Fault Seal
  • Permeability Measurement
  • Trap filling
  • Modelling of Charging and Leakages

Sealing processes and the concept of sealing efficiency and integrity, indicating seal breaching of the top seal by various processes, can be illustrated in the laboratory and calibration adapted to various fields. This training will provide you with standard faults lateral boundaries algorithms and scales for assessing roles of different fault types in trap filling or retention.  Understanding these is important before engaging in oil well operations and actual drilling, as well as field development and optimisation of assets.

 The training is adapted for beginners and advanced geoscience personnel, drillers and reservoir engineers.

Cost: N120,000 ($400) per candidate   (50% discount for students)

Duration: 5 days

Minimum 3 candidates for in-house training / 5 candidates for student group.

USING OUR HERITAGE TO RIDE TO THE RENEWABLE ENERGY FUTURE

As the world sounds the prepare-to-abandon alarm on petroleum resources, developing oil host nations must (like the ship masters) muster the most competent men and stay back just a little more to ensure that it is not a false alarm, and to as well get the best of the life boats to ride safely to the Energy future – rather than jump to sea. #oilforall

REDISCOVERING THE PETROLEUM POTENTIAL OF THE ANAMBRA BASIN

* In this collaboration of key Industry professionals and University, is a training involving indoor and field trips to unravel the full chain potentials of the petroleum system from EXPLORATION, through APPRAISAL and DEVELOPMENT to PRODUCTION.

* With key oil and gas players beginning to drill in the Anambra basin, we intend to develop skills and get people involved in the opportunities, including in unconventional hydrocarbons.

This training is residential, logistics and welfare are fully covered. Participants will arrive the guest house on Wednesay and depart Sunday. Detailed joining instructions will be sent to registered participants.

PERMEABILITY CHANGES WITH CHANGING DEPTHS

Weekly Petroleum Geoscience Digests

Permeability changes with changing depths – 04 September 2017

  • By Dr Livinus Nosike

If rocks cannot allow fluid to pass, then we cannot extract the oil and gas in them while drilling.  We will have to pump acid into the hole to dissolve the rock and create spaces, or we use water to push out this fluid by force.  But how do we know if the rock will or not allow fluid to flow at the depth of petroleum reservoir?  How do we compare between the permeability of muddy rock (shale) or sandy rock (sandstone)?

We cut out such rock on the surface by a process known as coring (see figures above). Then put the cut out sample in cellophane, waterproof, with a tube through which fluid can flow.  We then put it into a compressible container known as pressure cylinder where we can pressurize the rock sample in stages, as they would be when buried at different depths. This way we simulate permeability variation with depth (increasing pressure and temperature while measuring the permeability).

We also reduce the pressure gradually to see what happens if a rock formerly buried is lifted up or exposed by erosion where it is less under pressure/load.  At the end we are able to know how a similar oil and gas reservoir rock will behave.

From this, you see that permeability measurement requires a lot of skills and precautions.  When measuring permeability, we use a filter to block either ends of the rock sample (see diagram above), so the grains do not scatter and block the measuring tube.  We flush the valves with pressured air to ensure no particle is trapped in the tiny holes of the flow tubes.

OIL AND GAS FLOW IN DIRECTIONS KNOWN AS ANISOTROPY

Weekly Petroleum Geoscience Digest

Oil and gas flow in directions known as anisotropy – 29 August 2017

  • By Dr Livinus Nosike

When a rock is buried, there is load above it.  Increasing soil or sediments above make it to compact and become planer.  Becoming planer means it is as if they are layers lying above each other, like several piles of sheets.  If fluid is to flow through a sheet, it will likely flow between the layers in the horizontal directions. Bending of buried rocks, known as folding or deformation, changes the original horizontal fluid flow directions.  Cracks and shifts, known as fractures and faulting of the rock layers, results in fluid choosing specific directions to flow. This preferential fluid flow direction is known as permeability anisotropy.

Permeability anisotropy is important because we care not only about the ability of fluid to flow in a rock, but also in which direction it will flow. If we know the direction petroleum fluid will flow, we put our pipe in that direction and extract it.  We also know where the fluid is coming from, where the oil and gas are generated, where more could be found.

To measure permeability anisotropy, we cut out cylindrical rock sample known as plugs, in three directions: upwards, along and across the rock, as shown in the illustration above. The process of relating this small plug, small cut out rock sample, to a larger oil and gas reservoir rock is known as upscaling. Not only do you need to upscale, you need to subject the rock sample to similar condition as if it were at depth.  That is why we subject the rock sample to different pressure condition, simulating burial of reservoir rock.

This is discussed in the next episode.
