| Association of Petroleum
Geologists (APG) and Society of Petroleum Geophysicists (SPG), Baroda Chapters
added yet another feather to their cap by jointly organising a day-long
geological field trip to a Point Bar along river Mahisagar near village
Umeta on February 12, 2005. This spot is about 25 km northwest of Baroda.
About hundred members of
APG and SPG of ONGC attended the field trip under the leadership of Shri
Gautam Sen, ED–Basin Manager Western Onshore. Geoscientists from HOEC also
participated.
The trip was preceded by
a short briefing, the previous evening, elaborating the Point Bar features
and causatives through a PowerPoint presentation. On the day of the field
trip, trenches were cut on the Point Bar to study the vertico-lateral sedimentary
features that are typical of a meandering stream viz. Channel Lag Deposits,
Planar & Trough Cross Bedding and Overbank Deposits.
The members took keen interest
in studying these features and were proactive in their approach through
interaction. The trip proved to be educative as it provided insight into
the processes involved in deposition of fluvial reservoir rocks. The field
trip was followed by a short quiz on geoscientific topics.
