STRATIGRAPHER AND PETROLEUM GEOLOGIST

Basin Analysis, understanding the stratigraphy, managing the exploratory drilling and post-drilling scenario in the business of Hydrocarbon Exploration

1. AS A STRITIGRAPHER:

A. Worked as a core group member for the standardisation of Lithostratigraphy of the KRISHNA- GODAVARI and CAUVERY Basins located on the East coast of India.

B. Carried Out the foraminiferal biostratigraphy of the Cretaceous to Recent sediments of the exploratory wells in the Indian Basins and the biostratigraphic studies of the wells drilled at Vietnam and Oman under the joint venture.
The study includes
• Dating of Samples from the study of index Foraminifera
• Recognition of Depositional Environment, paleobathymetry, Transgressive-Regressive Cycles and Sea Level Changes.
• Identification of Anoxic Events and their bearing on source- Rock Facies
• Real Time dating (At well site) of samples for the immediate decision of Logging, Casing points and extrapolation of Well Data on the Seismic Sections for proper co-relation of Subsurface Data.
• Calculation of Span of Hiatus, Recognition of Flooding Surface (MFS), Condensed Sections.
• Integration of biostratigraphy , sedimentology, well log data and seismic facies to understand the depositional systems.,operating in the Basin

C. Established the evolutionary trends of Miogypsinidae from the Krishna-Godavari,Cauvery and Andaman basins and calibrated the Miogypsinidae scale with the planktonic foraminiferal zonal scheme

D.Carried Out Sequence Stratigraphy of the Upper Assam shelf Basin covering the Rudrasagar, Lakwa and Geleki Oil field Area.
2. AS A WELL SITE GEOLOGIST
A. Shallow water Wells
• Carried out monitoring of geological Operations on well site for the Exploratory Wells in the Offshore of Western Indian Self B. Deepwater Wells
• Carried out the well site Geological Studies on a fifth generation deep water rig
.Selection of Sidewall core, MDT pre-test and Sampling points from the study of logs at well site.Coring and Core Analysis and priority dating of samples at the well site, from foraminiferal studies
• Study of Wire Line logs, cutting, core and sidewall cores and building the stratigraphic Column.
• Electro log Correlation.
• Identification of Hydrocarbon bearing Zones and perforation intervals.
• On line monitoring of LWD and mud logging data for detailed monitoring of drilling Operation.
• . Planning and monitoring of well site operations for the effective Rig time management
