Best Paper Award of the 20th Formation Evaluation Symposium 2014
The best paper was selected from 22 papers presented at the 20th Formation Evaluation
Symposium of Japan, held at JOGMEC-TRC on October 1st and 2nd, 2014. For this selection,
the board members reviewed all papers at the previous board meeting and chose the awarded
paper by the voting. The testimonial will be given to the awardees at the coming JFES
Symposium of this year. The awarded paper and the authors are shown below.
PETROPHYSICAL ANALYSIS OF A TIGHT SILTSTONE RESERVOIR:MONTNEY FORMATION, WESTERN CANADA
Takashi Akai (1) and James M. Wood (2)(1) Japan Oil, Gas and Metals National Corporation(2) Encana Corporation

The authors measured petrophysical properties of siltstone plug cores collected from the EarlyTriassic Montney tight gas fairway in the Western Canada such as porosity, permeability andTotal Organic Carbon (TOC) by using advanced laboratory apparatus such as NMR, micro
focus X ray CT imaging and Focus Ion Beam Scanning Electron Microscope (FIB/SEM).
Based on this research, following points have been clarified:
1.

2.

3.
4.

A significant porosity and permeability trend was obtained for plug samples measured underconfining pressure conditions by use of micro focus X ray CT imaging to detect and omit samples
with artificially induced internal cracks.
An inverse trend between porosity and TOC was observed and explained in terms of the Montney
petroleum system. And, thermally degraded bitumen which plugs the paleo-porosity network wasfound by high resolution SEM imaging.
Porosity estimation was conducted by use of both dry-NMR and wet-NMR.
3D pore and organic structures were visualized by use of FIB/SEM.

For tight gas reservoirs, to identify “sweet spots” is important to develop with lower cost andefficient processes. This research enables to discuss gas generation and storage mechanisms
and the range of reservoir quality by use of advanced laboratory apparatus. The results of thisstudy will lead to “sweet spots identification” of tight reservoirs. This paper is worth to receive
the best paper for the JFES Symposium 2014.

Invitation to the 90th Chapter Meeting
We are pleased to announce that the forthcoming Chapter Meeting will be held as follows. Those
who are interested in attending this meeting are asked to send an e-mail registration at JFESNewsletter@slb.com no later than February 27th, 2015.
Date & Time: Wednesday, March 4, 2015, 15:30 – 17:30
Venue:

Mitsui Oil Exploration Co., Ltd.
Hibiya Central Bldg, 10th Floor (Presentation Room A & B)
2-9 Nishi-Shimbashi 1-chome, Minato-ku, Tokyo 105-0003, Japan

Program:First talk: Petroleum exploration and development of fluvial sandstone reservoirs in thenorthern Phitsanulok Basin, onshore Thailand
Presenter: Katsuro Moriyama
Biography: Katsuro Moriyama has 20 years’ experience as a geologist for exploration project.
Katsuro worked at operator for Thailand project for 7 years as geologist and exploration
manager.
Abstract: The Tertiary Phitsanulok basin is well known for the Sirikit field which is the largest
onshore oil field in Thailand. Geology of the basin is similar to that of Gulf of Thailand. Moeco,
who has produced oil and gas in the Gulf as a non-operator for 30years, has applied thetechnologies used in the Gulf, and successfully discovered oil, and is currently producing.
Second talk: Current situation of shale gas development in US
Presenter: Takeshi Onishi
Biography: Takeshi Onishi has 12 years’ experience as a reservoir engineer for development
projects for both conventional and unconventional oil and gas reservoirs. Takeshi worked at anoperator for shale gas project in US for the last 3 years and served reservoir engineering andcompletion operation including hydraulic fracturing.
Abstract: As activities of shale gas development have been significantly increased, gas
production from shale occupies the important position in US. Key factors for the development
are horizontal drilling and hydraulic fracturing.
This presentation shows basic operation procedure of hydraulic fracturing. Technical trends forthe shale gas development are also presented.
