In Saturday ( Mar 3rd) AAPG SC ITB held a lecture themed “ Introduction to Petrophysical Analysis and Integrated Approach to the Study of Clastics and Carbonate Reservoirs”. The speaker of this event is Mrs. Mike Wulansari as a BP’s representative. She is a Petrophysicist who has been worked for 4 years. Maybe not all of you have known about what is petrophysics. Petrophysics is the science dealing with the fundamental chemical and physical properties of porous media, and in particular of reservoir rocks and their contained fluids. These include storage and flow properties (porosity, permeability and fractional flow), fluid identification, fluid phase distribution within gross void space (saturation), interaction of surface forces existing between the rock and the contained fluids (capillary pressure), measurements of pressure, stress condition, electrical conductivity of fluid saturated rocks, etc. These properties and their relationship are used to recognize and assess hydrocarbon reservoirs, source rocks, cap rocks, and aquifers.
Mrs. Mike Wulansari giving a presentation
Petrophysics remains a vital component to many facets of the petroleum industry, from quantification of hydrocarbon reserves, developmental strategies to real-time decision making for reservoir navigation. Learning about the latest geological, geophysical and logging/core technologies are important to understand better their role in petrophysical analysis, formation evaluation, and reservoir characterization. Petrophysical properties form a set of essential engineering parameters and still remain the basic tools to obtain reliable information by which reservoir rocks may be described quantitatively, in order to assist petroleum engineers in the evaluation of hydrocarbon reserves and for planning well completion and optimize production operation during the reservoir life.
Petrophysical Analysis is designed to encompass the spectrum of information that can be derived from examination of standard open-hole logs. Basic petrophysical interpretation to calculate porosity, shale volume, fluid saturation, grain density, and permeability will be covered. Advanced analysis will include detail examination of porosity log responses, relation between porosity and water saturation, and a discussion of capillary characteristics. Mrs. Mike also explain about BP’s Gas Field in Tangguh, Papua, Indonesia. The participants are really enthusiastic and they ask a lot to know about petrophysics. BP also give souvenirs like bag and notes for the participant who ask a question or answer the quiz from BP.
