STRUCTURAL UNCERTAINTY ASSESSMENT TRAINING: 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 and young professionals)

Duration: 5 days

Gas While Drilling (GWD), Measurement, Interpretation & Applications

With the new drive to gradually replace oil with gas, interest in gas deposits is becoming a national and international policy. Oil deposit usually have associated gas and before reaching reservoir targets, information from biogenic and thermogenic gases can provide useful guide in well drilling, petroleum results and field development. Our Gas While Drilling module aims at optimising Gas Technology skills for individuals and corporate organisations in the industry. Taking advantage of this online edition will help you acquire skills on:

Gas Measurement

  • GWD Principles
  • Gas Units and Gas Concentration
  • Primary Dry and Secondary Wet Gases
  • Gas System Sensors and Calibration
  • Chromatograph: Total Gas and Components
  • GWD Technology: Set up, Extraction, Analysing and Fingerprinting

Gas Interpretation

  • Gas Sources and Types (TrG, Swab, CG, CirG, RG, BGG, FG)
  • Analysers: Constant (CVA) and Variable Volume (VVA) Analyser
  • Gas Quality Control (QC) and Indicators
  • Gas Line Checks and Chromatography Checks
  • Assessment Curves: Saturation, Separation and Consistency
  • Wetness, Balance and Character

GWD Applications

  • Direct Hydrocarbon Indicator (DHI)
  • Fluid Characterisation and Biodegradation
  • Fluid Evolution and Compartmentalisation
  • Lithological Characterisation and Rock Type
  • Seal Analysis and Trap Quality
  • Pore Pressure Surveillance and Gas-Aided Drilling (GAD)
  • Integration with Drilling Parameters
  • Integration in Masterlog and Well Reports

I look forward to having you participate, and as usual, we are going to have a nice time giving all that is required to make the session a classroom and hand-on experience, for each participant. The testimonials of our trainees speak volume!

Intensive Weekend Training on PORE PRESSURE PREDICTION

Pore Pressure Prediction is perhaps the most important skill to acquire in the extractive energy industry. A skill you must get at some point, and better early, in your professional pursuit.

·         It is the basis of safe drilling and prediction of petroleum results.

·         It forms the basis for collaboration between geoscientists and engineers, as well as other métiers in oil companies.

·         It integrates every other aspect of the E and P value chain, from exploration to production, through well geology and petrophysics, to well follow up and reporting.

·         Knowledge of geopressure, and the ability to predict or understand abnormal pressures, sets personnel apart in any team or department in the workplace and at operational sites.

·         Unfortunately, many candidates miss this training and the skills are reserved for just few who eventually excel in their career.

This opportunity comes to you at this time, to learn the tools of PPP in a simplified manner, necessary for your future career or current evolution at work.

We look forward to your participation in this upcoming training.
