CALGARY, AB--(Marketwired - May 23, 2017) - Altitude Resources Inc. (TSX VENTURE: ALI) has acquired two new Alberta Crown coal lease applications adjoining its Altitude North property in west central Alberta. The additional applications cover an area of 4,144 hectares (see map). The Altitude North property is approximately 60 km north-west of the ALI's Palisades Coal Project and is immediately adjacent to the Grande Cache Coal Mine property. The Altitude North Project is in close proximity to CN rail, providing access to both Vancouver and Prince Rupert ports. The addition of the new lease applications increases the company's land position at its Altitude North Project to approximately 14,080 hectares. Altitude is planning a 2017 field program to identify coal structure, coal quality and future drill targets. In 2015 ALI announced that it had discovered a multiple near surface mid volatile coking coal deposit at its Altitude North property. The property stretches over a length of 23 km (northwest to southeast). Seven individual seams were identified ranging in estimated true thickness from .3 to 6.0 meters. Significant coal seam intersections were identified and stretched along the entire extent of the property. Testing indicated the coal rank to be Mid Volatile Coking coal. Initial historic Alberta government exploration reports showed some coal outcrops which were identified from field work in the 1960 - 1980s but there are no reports of any field drilling. ALI has initiated permit applications with the Alberta Government for a drill program at the Palisades Coal Project located in west - central Alberta, Canada. Palisades Extension, an area adjacent to Palisades on the north boundary is to be included in the drilling program for the first time. A 2,500 meter drill campaign has been recommended to evaluate and constrain the drill and mapping targets. This work includes approximately 2,000 meters of reverse circulation drilling and up to 500 meters of wireline coring in target areas identified by the 2016 program. The drill permit is expected to be valid for two years. The ALI-JOGMEC Joint Venture approved the 2017 program under the Third Farm-In of the Joint Exploration Agreement signed in 2015. The budget for the 2017 campaign is CDN $1,200,000. JOGMEC has now fulfilled its obligations under the Second Farm-In and has now earned a 31.875% interest in the Palisades project. The drill targets in the proposed program were identified during the 2016 exploration campaign. Dahrouge Geological Consulting (Dahrouge) of Edmonton, Alberta has been contracted to oversee the proposed 2017 drill program. It is expected that the approval will be received in the calendar Q3 2017 and the program is expected to start shortly after. Commenting on the upcoming program, Gene Wusaty, President and CEO said, "We are very pleased with the expansion of our Altitude North leases and planning for our 2017 filed program. The planned 2017 drill program will test new coal targets identified in the 2016 field exploration as well as incorporating the Palisades Extension for the first time. We expect the program will result in more extensive coal quality analysis as well as provide the opportunity to increase our resource base at Palisades." Gene Wusaty, President & CEO, a qualified person as defined by NI 43-101, supervised the preparation of the technical information in this release. Altitude Resources is a Canadian coking coal exploration and development company focused on developing its portfolio of coking coal properties in the province of Alberta, Canada. Altitude's properties are all located within close proximity to rail with spare capacity and the ability to provide transport of coal to deep-water ports on the west coast of Canada to service the growing demand from world markets.

We examined the petrography, petrology, and geochemistry of two types of gabbroic xenoliths (A-and B-type xenoliths) in olivine basalt and biotite rhyolite units among the dominantly rhyolitic rocks in Niijima volcano, northern Izu-Bonin volcanic arc, central Japan. A-type gabbroic xenoliths consisting of plagioclase, clinopyroxene, and orthopyroxene with an adcumulate texture were found in both olivine basalt and biotite rhyolite units, and B-type gabbroic xenoliths consisting of plagioclase and amphibole with an orthocumulate texture were found only in biotite rhyolite units. Geothermal-and barometricmodelling based on mineral chemistry indicated that the A-type gabbro formed at higher temperatures (899-955°C) and pressures (3.6-5.9 kbar) than the B-type gabbro (687-824°C and 0.8-3.6 kbar). These findings and whole-rock chemistry suggest different parental magmas for the two types of gabbro. The A-type gabbro was likely formed from basaltic magma, whereas the B-type gabbro was likely formed from an intermediate (andesitic) magma. The gabbroic xenoliths in erupted products at Niijima volcano indicate the presence of mafic to intermediate cumulate bodies of different origins at relatively shallower levels beneath the dominantly rhyolitic volcano. © 2017 Y.

The development of reliable systems for monitoring injected CO2 is essential in carbon capture and storage projects. We applied time-lapse surface wave analysis to measure temporal variations of the shallow subsurface among 11 periods (0.2-21.6days) of continuous seismic data acquired from 2014 to 2016 at the Aquistore CO2 storage site in Canada. We focused on monitoring environmental influences on shallow seismic velocity, which are unrelated to CO2 injection into deep reservoirs. A continuous, controlled seismic source system called Accurately Controlled Routinely Operated Signal System was used to enhance the temporal resolution and source repeatability. Observed phase velocities were clearly higher in winter than in warmer seasons. The seasonal variation could be reproduced by an increase in the shallow S wave velocity during winter associated with the greater extent of freezing of partially saturated rock. We also observed gradual increases or decreases in phase velocities as the seasons changed, which could be related to gradual freezing or melting of ice. Our monitoring system thus could be effective for monitoring temporal variations of the shallow subsurface associated with the degree of freezing. Furthermore, the high temporal stability of our monitoring approach in warm seasons may make it possible to immediately identify CO2 leakage in the shallow subsurface. ©2017.

The world's largest underground storage facility for Liquefied Petroleum Gas (LPG) was constructed in Cretaceous granitic rock in the Inland Sea near Kurashiki in western Japan. This facility is being operated using a water curtain system in order to control the flow of groundwater and pore pressure, thereby ensuring long-term safe LPG storage. Grouting was also conducted during the excavation of rock caverns so as to control the hydraulic conductivity of the rock mass appropriately. Pre-excavation grouting was conducted under high grouting pressure (about 4.2 MPa) in order to control the hydraulic conductivity below 0.35 Lugeon. Also post-excavation grouting was carried out if the inflow exceeded the requirement. After the excavation of the grouted areas, the effects of grouting were checked by measuring the inflow rate and the pore pressure around the storage caverns. If needed, geological survey, analysis of measurement data, and analysis of grouting data were carried out and grouting designs were rationally revised step by step in terms of grouting equipment, grouting materials, grouting patterns, and criteria of additional holes. The main grouting material was super-fine cement for the whole of the cavern. However, a micro-fractured zone (mf-zone) was encountered, where improvement effect with cement grout was limited despite many changes in grouting design made. In this zone, colloidal silica grout (CSG) was used as a supplement, after confirming its suitability for long-term sealing at the Kurashiki Base. Because of little precedent of using CSG for rock grouting in Japan, specifications of CSG grouting were reviewed and adjusted based on information-based technique. The results of pre-grouting with CSG in the cavern indicates that the mf-zone where improvement of sealing effect was not sufficient when using cement grouting, has been improved using CSG. As a result, the inflow to the LPG caverns and the groundwater pressure around the caverns after the completion of construction were within the scope of the prediction. © 2014 by Japanese Committee for Rock Mechanics.

Petrological and geochemical investigations were performed on the uniquely distributed Nanzaki basanite (0.43Ma) in the northern part of the Izu-Bonin volcanic arc, Japan, to clarify its original magma chemistry, and to constrain the source mantle and formation process of the magma. The Nanzaki basanite (monogenetic volcano) is mainly composed of nepheline-bearing basanite lava and scoria. The mineral chemistries are characterized by high forsterite (Fo) contents of olivines, high Mg# (=Mg/(Mg+Fe)) values of clinopyroxenes, and low Cr# (=Cr/(Cr+Al)) values of spinels. Whole-rock major element contents have narrow variation ranges as follows: SiO2 (41.5-44.1%), MgO (10.2-13.1%), CaO (11.9-13.3%), and K2O (0.4-1.9%). Combined with these mineral and whole rock chemistries, the low FeO*/MgO (0.81-1.09) values, high Ni and Cr contents, and narrowly distributed rare earth element (REE) patterns of the Nanzaki basanite represent the primary (undifferentiated) chemical features of the magmas. The incompatible trace element characteristics, especially the high Sr, Ba, and REE contents and low K, Rb, Zr, Hf, and Ti contents, suggest that the basanite magmas were generated from an enriched mantle that was affected by metasomatism with carbonatite magma (or carbonate-melt). In addition, the slight enrichment of Pb, Cs and other alkaline elements in the basanites indicates the close concern of fluids, and the Sr-Nd isotope characteristics of the basanites (low 87Sr/86Sr and 143Nd/144Nd ratios relative to those of basaltic rocks in the volcanic front) are consistent with across arc isotopic variations of the Izu-Bonin volcanic arc. The metasomatism of the source mantle by carbonatite (or carbonate-rich) melt was associated with and potentially facilitated by the infiltration and interaction of some volatile components (CO2, H2O) from the subducting slab. Thus, it is presumed that the enriched and metasomatized mantle parts have been present, ubiquitously in some regions of the mantle wedge, and that the basanitic magma, as in the Nanzaki, has been generated in close association with the unique tectonic regime, as in the northernmost part of the Izu-Bonin volcanic arc where three (or four) plates converged. © 2013 Elsevier B.V.

It is very important to evaluate the soundness of the injection site by simulating the behavior of carbon dioxide injected into the reservoir. Monte Carlo approach is often used for the statistical evaluation of reservoir because its models include much uncertainty. This approach requires a large number of simulations and it is very time consuming. Therefore we accelerated the simulation with GPU (Graphics Processing Unit) computing technology. We used the simulator called TOUGH2/ECO2N. As a result, we achieved acceleration rate more than 8 times with the simulation for the three-dimensional reservoir model of the Nagaoka project site having 110,000 grids.

A method for determination of the solubilities of methane and carbon dioxide in high-pressure water was developed by direct injection of the sample into a gas chromatograph column. This method used a DVB-EVBEGDMA packings (80-100 mesh) packed column (3 mm i.d.×2 m). The column temperature and carrier gas flowrate were optimized for the separation of methane, carbon dioxide and water. The measurement accuracy was greatly improved by installing a check valve in the gas supply system. Solubilities of methane and carbon dioxide were determined from the values obtained from the absolute calibration curve.

This paper presents a new constitutive model that simulates the mechanical behavior of methane hydrate-bearing soil based on the concept of critical state soil mechanics, referred to as the "Methane Hydrate Critical State (MHCS) model". Methane hydrate-bearing soil is, under certain geological conditions, known to exhibit greater stiffness, strength and dilatancy, which are often observed in dense soils and also in bonded soils such as cemented soil and unsaturated soil. Those soils tend to show greater resistance to compressive deformation but the tendency disappears when the soil is excessively compressed or the bonds are destroyed due to shearing. The proposed model represents these features by introducing five extra model parameters to the conventional critical state model. It is found that, for an accurate prediction of ground settlement, volumetric yielding plays an important role when hydrate soil undergoes a significant change in effective stresses and hydrate saturation, which are expected during depressurization for methane gas recovery.

The water samples collected from two non water-flooded oil fields contained a variety of organic acids, sulfatereducing bacteria (SRB) and little sulfate. Acetate and propionate were the major components of organic acids. Over 6 weeks of artificial souring experiment, a maximum of 3 mM of sulfide was produced when oil field water was mixed with seawater at 25°C. Propionate was completely consumed under soured conditions. This indicated that the propionate-consuming SRB underwent souring in this experiment. Significant cell growth was confirmed at 25°C with no relation to souring. The dominant SRB species were shifted from Desulfomicrobium thermophilum to Desulfobacter vibrioformis and uncultured Desulfobacter © 2010 The Society of Chemical Engineers, Japan.
