Southern central Hokkaido is an important hydrocarbon province and over 100 wells were drilled by METI and private companies in the past 50 years. The rea can be divided into three zones(Zone I, II and III) from the structural styles and stratigraphy, both of which are revealed by the extensive exploration activity. Zone I is characterized by basement horst structures and located in the west of the area. Zone II also has basement horst structures but its shallow sediments are thrust faulted. The ...

A Miocene-Upper Cretaceous section of the MITI Tempoku borehole, northern Hokkaido, was subdivided into seven dinoflagellate cyst assemblage zones. Biostratigraphically useful pollen and spore assemblages were also recorded from the lower Paleogene-upper Upper Cretaceous part of the section which is mostly nonmarine or deltaic. The combination of these organic microfossils established a fundamental biostratigraphic-chronostratigraphic framework in the section, where the recovery of other calcareous ...

The thick Cretaceous-Tertiary sediments which cover the Tenpoku and Haboro area, the northern part of Hokkaido, is believed to possess substantial hydrocarbon potential. More than seventy anticlinal structures have been recognized in this area, but to date only eight wells have penetrated the Paleogene section while four have drilled to Cretaceous sediments.Four types of anticlinal structures are recognized as interpreted from well data and seismic profiles. The Kitakawaguchi feature represents ...

A possible mechanism of a hydrocarbon trap in the Neogene porcelanites in northern Hokkaido, Japan is discussed through petrographic and pore throat size analyses. In the studied two wells, quartzose porcelanites with lesser amount of clay and located at shallower depth have a higher reservoir quality associated with hydrocarbon shows and gas production. It indicates that matrix pores as well as fractures play an important role in the hydrocarbon trap in siliceous rocks. In the Yurihara Oil and ...

Diatom biostratigraphy was examined for the upper Miocene to Pliocene sequence distributed in the Yufutsu oil and gas field located in southern central Hokkaido, Japan.The Denticulopsis praedimorpha and Denticulopsis dimorpha Zones were recognized in thin volcanic reworked sediment with glauconite, which overlies just above the Takinoue volcanics oil reservoir. The result indicates that the condensed glauconite bed had been formed for a long time, from the end of Takinoue volcanic activity through ...

The collision of the Kuril arc against the Northeast Japan arc has made a conspicuous crustal structure from the Hidaka mountain range to the Ishikari-Tomakomai lowland, Hokkaido, Japan, since Miocene. Recent advance of deep seismic reflection studies has revealed that the Kuril arc lithosphere is delaminated at about 23km deep in the lower crust in the Hidaka collision zone. The upper half of the lithosphere (upper crust+upper portion of the lower crust) is thrust westward on the Northeast Japan ...

Yufutsu field is located in the southern Ishikari Plain, central Hokkaido, in northern Japan. Japex commenced the production in 1996 and is producing gas and condensate. The reservoir is a naturally fractured granite and conglomerate. The permeability and porosity is very low. The reservoir is so heterogeneous that it cannot be modeled with the conventional method. We modeled it with the discrete fracture network (DFN) model by using the statistical properties of the fractures extracted from static ...

It has been a long time dream of Japan Petroleum Explolation Co., LTD (JAPEX) and local energy sectors to have a large oil and gas field in Hokkaido. In Hokkaido, nearly a hundred wildcats have been drilled by JAPEX since late 1950's. In 1988, JAPEX finally discovered a large gas field by the well “Minami-Yufutsu SK-1” which is located a few kilometers northeast of Tomakomai-City. Since then, JAPEX has drilled ten wells and discovered three gas pools. The field is now called Yufutsu Gas Field.Though ...

This paper discusses the methodology for fracture detection and fracture porosity evaluation through core description, mud log and well logs, using data from Yufutsu gas field, Hokkaido, Japan. The youngest fracture group observed on core (System C) consists mainly of open fractures and roughly correlates with the conductive type fracture image on FMI. The remaining core fracture groups (System A and B) are filled by minerals and correlate with the resistive type fracture image. These results suggest ...
