| [Abstract] To better understand the combustion characteristics
of DME, emission intensities of DME combustion radicals
from a pre-mixed burner flame were measured by a spectroscope
and photomultiplier, Results were compared to other fuels,
such as methane and butane. Large peaks in the band spectra
from pre-mixed and diffusion DME flames were found near
310 nm, 430 nm, and 515 nm, arising from OH, CH and C2,
respectively. The DME emission intensities decreased with
increasing the equivalence ratio in this study. Notably,
the relative decrease in the C2 band spectra peak was
greater than that of the OH band. Comparing the pre-mixed
DME and butane flames, the butane band spectra peaks were
similar in shape, but much stronger than those for DME.
However, it was remarkable that CH and C2 band spectra
peaks decreased only slightly with increase in equivalence
ratio compared to the DME case. In case of the butane
diffusion flame, there was a continuous spectrum above
430 nm, presumably due to thermal radiation of soot. |

R&D Activities on the Emerging Gas Technologies
- New & developing market opportunities |
The 12th International Oil, Gas and Petrochemical Conference

[Abstract] The total of current proven natural gas reserves in
the world are estimated as 880 billion boe and this amount
surpasses the total of proven oil reserves. The natural
gas is expected to serve as the major energy resource
to cover world energy demand for the rest of the 21st
Century due to its lower environmental load as well as
to its larger reserves.
Gas To Liquid (GTL) and Natural Gas Hydrate(NGH) technologies
will enhance exploration and development of smaller and/or
stranded gas reserves, by contributing for widening of
Natural Gas usage and Lowering Transportation cost. Development
of new market opportunities for Natural Gas, such as Di-Methyl
Ether(DME) for fuel cells should be worth to study for
further promotion of natural gas utilization.
Current status and R&D activities of the emerging
gas technologies conducted by Japan National Oil Corporation
and Japanese Companies specifically on GTL, NGH and DME
will be presented. The speech will also include short
summary on R&D activities and current plan on methane
hydrate as a possible energy source for the latter half
of the Century. |

[Abstract] In RAEG in 2002, we showed the roadmap (Hato et al.,
2001) of developing seismic method for methane hydrate
(hereafter MH) exploration following the scheme of the
national project. In that paper, we showed high performance
of interval velocity to delineate MH-bearing zone (MHZ)
and related low velocity zone (hereafter LVZ) inferred
to presence of free gas. During past one year, we have
promoted the interval velocity analysis by focusing on
the migration velocity analysis (PSDM/MVA).
In addition, in order to confirm availability of other
seismic methods for MH exploration, we have tried seismic
impedance inversion and an AVO analysis to the seismic
data. As a result, we confirmed that PSDM/MVA can economically
describe global variation of interval velocity, but canft
always delineate detail variation.
Regarding the seismic impedance inversion as a tool of
the high-resolution impedance mapper, the result of impedance
inversion shows that this method can delineate impedance
structure generally in detail but still has slight mismatch
with well data to be considered. Lack of properly-located
wells and inaccurate well data is thought to bear those
mismatches.
For the AVO analysis, although we are still running analysis,
we have so far convinced of the availability of AVO analysis
for MHZ and LVZ delineation. |

Fast and Robust Computation of Effective Permeabilities |

[Abstract] The current requirement of geologic detail to be built
into reservoir descriptions has been exceeding the computational
capabilities of reservoir simulation due to a need of
huge number of simulation grids. This has motivated the
development of a variety of upscaling techniques for flow
simulation.
This paper presents an efficient upscaling method effective
for an oil-wet heterogeneous reservoir, which offers a
means of simulating multiple geostatistical realizations.
A new effective permeability correlation is developed
through application of one of the non-parametric regression
techniques to the results of intensive numerical experiments.
The developed empirical correlation enables us to compute
effective permeabilities fast and accurately for a wide
variety of heterogeneous permeability fields from layered
to random system and can be easily extended for averaging
two-phase flow properties under viscous limit or capillary
limit.
The paper describes the developed technique in detail
and demonstrates how the overall upscaling procedure can
be speeded up with the desired accuracy. |

[Abstract] In this study, for better understanding the fuel properties
of DME, lubricity, viscosity and combustion properties
were investigated. The lubricities of DME were evaluated
by using pressure resistant type High Frequency Reciprocating
Rig (HFRR), which was developed for this investigation.
The lubricating additives were also evaluated that was
needed for practical use.
The mission intensities of DME combustion radicals from
pre-mixed burner flame were measured using spectroscope
and photomultiplier by comparison with other fuels such
as n-butane, methane. Large peaks of band spectra from
pre-mixed and diffusion DME flames were shown near 310
nm, 430 nm and 515 nm, and those are OH, CH and C2 bands
respectively. |

[Abstract] The crosshole tomography experiments were carried out
from the end of February to the beginning of March 2002,
using the two observation wells located at 80m apart each
other. The objective of this experiment is to detect the
change in physical property in the methane hydrate zone
caused by the production test by warm water injection.
In the science meeting held on Ottawa in July 2001, JNOC
science team suggested the possibility to detect the small
variation of elastic modulus by means of a full waveform
inversion based on the model simulation studies for thermal
production test, though the anomaly area would be so small.
The field data is characterized by the predominant tube
waves and strongly attenuated in the methane hydrate zones.
The data analysis was started from July 2002 and the interim
results were discussed at Kingston with the other science
teams on September 2002. In the meeting at Kingston, JNOC
team handled with the third survey data, because the baseline
survey data has serious problem on its geometry induced
in data acquisition. Some test to eliminate the tube waves,
were conducted and it was found that the f-k filter is
most effective process. First of all in the data processing,
a f-k filter was applied to suppress them which were occurred
at source and receiver wells. In order to investigate
the small physical anomaly in the methane hydrate zone
by the thermal production test, each repeated survey was
compared with the difference between the baseline survey
and the third repeated survey will be supposed the most.
JNOC team has tried to correct the depth error caused
by the field operation, and now it is not yet complete.
Now JNOC team is considering the amplitude attenuation
is very interesting information and we believe it is a
good attribute to identify the hydrate zone from reflection
seismology. JNOC team will start attenuation tomography
approach soon. |
