Modern Clastic Depositional Environments of Java

Course Details

The best way to develop a thorough understanding of the spatial distribution of reservoir quality sands is to take a field trip to a modern coastal plain and nearshore environments. That is the goal of this field trip offered along an estuary of the Kali Opak River along the Indian Ocean. We will examine the planform geometry of coastal plain rivers and discuss their expression on seismic and log data before heading out and walking the coastline.

This field trip is only taught in conjunction with our classroom course on fluvial and shallow marine reservoirs and compliments a field trip to look at ancient examples of shorefaces, barrier islands and estuaries in the Book Cliffs of USA.

This field trip is made possible by our friends and partners at PT. Geoservices – the premier oil and gas training company for Southeast Asia.  The course will be offered between December 10-14 2018.


This is an ‘awareness’ level course that we recommend for all experience level geologists, geophysicists, petrophysicists, engineers and managers. The course starts and ends in Yogyakarta, Indonesia and introduces participants to the processes that control reservoir deposition, distribution and architecture along wave dominated, river influenced, tide affected coastlines.

Course Outline


8:00 am - We will be gathering at the hotel meeting room for a safety briefing and orientation to the field area.

9:00 am - We will gather at the hotel lobby and take ground transportation to Kretek where we will stop along a point bar of the Kali Opak river. We will discuss permeability anisotropy and fluid BTT when waterflooding fluvial reservoirs.

10:00 am - We will continue our way towards the coastal plain stopping along the margins of the estuary to examine facies.

11:00 am - 12:00 pm - Once at the beach we will have an early lunch while the instructor organizes the digging of trenches.


12:00 -1:00 pm After having lunch we will spend some time looking at sedimentary structures exposed in a beach perpendicular trench. We will also discuss the log expression of shoreface reservoirs and the development of wave dominated parasequences.

1:00 - 2:00 pm We will examine the spit bar and rapid changes to its morphology in the past ten years and how this relates to interpretation of sub-surface data from nearshore environments.

2:00 - 3:30 pm After examining sedimentary structures in two other trenches we will load up and head back to the hotel in Yogyakarta.

This field trip is made possible by our good friends and partners at PT. Geoservices in Jakarta, Indonesia. To register for the course please e-mail us such that we can get you in touch with them.
