Introduction to Clastic Reservoirs

Course Details

This is a 2-day field course that starts and ends in Chakwal, Pakistan. The course introduces participants to some of the most spectacular fluvial outcrops in the world. The Siwaliks are the longest continuous fluvial succession in the world and with 20 years of field experience in the Siwaliks and Salt Range, we have picked some ‘text-book’ examples of reservoir architecture. The second half of the course is devoted to tide-influenced deltas of the Permian Nilawahan Group where we have funded university students to measure over 35 closely-spaced stratigraphic sections.

Please bear in mind that this is an ‘awareness’ level course and is not taught at the same level as our advanced 5-day course on Sembar and Lower Goru in the Book Cliffs of the U.S. We do understand the limitations of the outcrops in the Potohar Plateau and budget constraints with overseas courses, which is why we have created this course for large (minimum of 10 participants) groups. This field-course is NOT a substitute for our 5-day course in the Book Cliffs of USA.

This is the first in a series of the three field courses designed to prepare you for the challenges in the Sembar and Lower Goru Reservoirs of Pakistan. Once you have completed this ‘awareness-level’ course we encourage you to take the ‘foundation-level course.’

WHO SHOULD ATTEND

The course is geared towards geologists, geophysicists, petrophysicists, engineers and managers who wish to develop a better understanding of reservoir quality, connectivity, compartmentalization, distribution, lateral continuity and geometry.

Course Outline

Day 1

We will gather at a meeting room in the hotel and cover the safety briefing, orientation and have classroom modules on clastic sedimentary structures and ichnology and fluvial sedimentology and stratigraphy.

Field excursion to look at exposures of the Miocene Siwaliks where participants will perform several exercises to develop a basic understanding of input parameters needed for channelized reservoirs such as channel stacking, width, channel belt width, sinuosity, channel proportion and its effect on reservoir connectivity, and the connectedness ratio.


Day 2

Classroom module on sequence stratigraphy and sedimentology of shallow marine clastics.

Field excursion to the Salt Range where we will spend the day comparing sub-surface datasets with outcrop observations. Participants will be divided into groups and will perform exercises on creating facies logs for input into geomodels and create pseudo-seismic facies to better understand the seismic expression of Sembar and Lower Goru strata.


This field trip is only offered upon request and requires a minimum of 10 participants. The cost per participant is $750 for 2 days and this includes one night stay in Chakwal or Kallar Kahar, all meals, transportation, exercise materials and field manual.

We have been asked why our field trips are so expensive. We guarantee you will learn more about the sedimentology and sequence stratigraphy of your reservoirs in the 2 days you spend with us than the past 2 years you have spent in the office, if you don't agree we will be happy to refund 50% of your tuition payment.
