Pressures and Overpressure in the Subsurface

3 Day Course
Pore pressure has a wide influence on the petroleum system and can be directly responsible for the success or failure of a prospect. For example, high pore pressure leads to more difficult to drill reservoirs with a narrow safety margin and it can also be the cause of dry holes due to seal breach. As such, an early understanding of the role that pore pressure plays in a basin is vital before deciding on where to drill for both trap risking purposes and for well planning.

In this course, Ikon harnesses our decades worth of experience in pore pressure, fracture gradient, and wellbore stability projects from basins across the globe to introduce basic and key concepts to the beginner, but also with enough detail and interest for those with some degree of subject familiarity.

The course is designed for geologists, geophysicists, petrophysicists and reservoir/drilling engineers who have an interest in, or need to utilise pressure data in their workflows, and wish to gain a deeper understanding of the relationships between geology and overpressure.

Detailed Course Overview
Examples of key topics of interest covered
  • Key criteria that define if an offset well is an appropriate analogue from which to base a well plan.
  • When should seismic velocity be used for pore pressure prediction? Is it fit for purpose?
  • Examples of breached traps and the circumstances in which they arise.
  • Highlight how ‘pore pressure’ may be interpreted differently by drillers/engineers/geologists.
  • Importance of sea water depth when comparing offset wells expressed in equivalent mud weight (EMW) units.
Case study discussion topics
  • Offset well selection in a mature petroleum basin and importance of considering the local structure.
  • A challenging well plan located on a sandstone horst block surrounded by variable lithology.
Practical exercises
  • How to analyse pressure data
  • How to calculate overburden and fracture gradients
  • How to use industry standard techniques to predict pore pressures in the pre-drill environment

Course Terms and Conditions
1. Ikon Science shall provide, at its cost, comprehensive training course materials comprising PowerPoint slides, worksheets, trainer notes and case notes as required for the relevant Ikon Science training course described above (the “Course”) and in sufficient numbers for all attending participants (the “Materials”). Such Materials are to include exercises and case studies as well as a selection of relevant articles (where available) that may be of use to facilitate further understanding of the subject matter.
2. The individual attending the training course (the “Attendee”) acknowledges and agrees that all intellectual property in the Materials belongs exclusively to Ikon Science or third party providers thereof (where applicable) and the Individual shall not acquire any express of implied interest therein. The Attendee shall not (i) copy or otherwise reproduce the Materials, (ii) use the Materials for commercial purposes or otherwise than for the direct purpose of completing the Course, or (iii) sell, lease, transfer, publish or otherwise make available or disclose the Materials or any part thereof (whether orally, in writing or in electronic form) to any third party (including any other person, company or any employee, officer or agent of the Attendee.
3. Ikon Science shall provide one (1) suitably skilled and experienced trainer who shall deliver the Course in a professional manner and otherwise in accordance with the objectives, target audience and outline set out in this letter.
4. This Course booking form must be signed by: (i) an authorised signatory of the company being invoiced for the Course (“Company”); or (ii) by the Attendee if prior payment has been made on a personal basis and in advance.
5. This contract for the provision of training is governed by English law and subject to the exclusive jurisdiction of the courts of England & Wales.
6. In the event that the Company issues a purchase order to Ikon Science which relates to training for a specified number of Company personnel in the use of Ikon Science software as specified therein, Ikon Science hereby grants to Company a non-exclusive, non-transferable licence for each such personnel to use the relevant software (“Training Licence”) provided by Ikon Science in connection with the such training (“Training Licence”) solely for such training purposes and for no commercial or other purposes whatsoever. Training Licence shall be installed by Company on such equipment as Ikon Science shall specify and, unless otherwise agreed in writing, each Training Licence shall expire seven days after its date of issuance. Save as aforesaid, Ikon Science’s standard software licence terms which are not inconsistent with the terms of this paragraph shall apply to all Training Licences granted hereunder.
7. All prices quoted are net of all relevant taxes (including VAT).
8. If full payment is not made on booking, it shall be required within thirty (30) days of the invoice date.
9. The Attendee or Ikon Science may cancel or postpone the training course by written notice to the other. In the event that the Attendee cancels the course up to thirty (30) days prior to the course taking place Ikon Science will refund in full any fee paid in respect of the training course. If cancellations are requested by the Attendee between 30 and 14 days prior to the agreed training course commencement date, Ikon Science reserves the right to retain 50% of the full fee. If such cancellation by the Attendee is made less than 14 days prior to the training course commencement date, the Attendee will forfeit the fee in full.
10. If a request for postponement of the training course is received at least 14 days prior to the course taking place, the Attendee and Ikon Science shall work together in good faith to agree alternative dates for the training course. For the avoidance of doubt, if the request is received within 14 days of the training course commencement date Ikon Science is under no obligation to agree an alternative date and the Attendee will forfeit their fee in full.
