： Gas hydrates are clathrate compounds in which guest molecule such as methane is in a cage formed by water molecules. Huge amount of carbon is considered to be stored in natural gas hydrates. Thus, gas hydrates attract much attentions as a major reservoir of carbon cycle and a possible future energy resource. It is important to understand reservoir properties of gas-hydrate-bearing sediments for prediction of gas hydrate dissociation behaviors. However, analysis of sediment samples containing gas hydrates is quite difficult because gas hydrates dissociate during coring, handling, and measuring processes. In this paper, we review a pressure-core analysis technology that is a unique technology keeping sample pressure within the equilibrium conditions of gas hydrates during handling and measuring processes. We categorize the pressure-core analysis technology into three generations according to the technological progress and summarize scientific findings. Finally, we discuss perspective of this technology within and beyond gas hydrate research.

GROUP REGISTRATIONS AVAILABLE! Contact us at spekl@spe.org to arrange your group. Natural gas is playing a central role in the primary energy mix, taking into consideration energy security, relatively small carbon dioxide emissions during combustion, ease of use and transportation, and so forth. Meanwhile, in the development and utilisation of natural gas today, "new challenges" have risen in proportion to the increase in reserves coupled with growing environmental awareness, climate change as well as the need to expand utilisation methods and more. This workshop will discuss innovative technologies used in natural gas development, storage, transportation and utilisation. 27 – 28 JUNE 2019 THE WESTIN TOKYO, JAPAN

： Geochemical characteristics and alteration process during diagensis of formation waters from the Yabase oil field, Akita Prefecture, are discussed using published data. The formation waters are divided into three groups （ type I: shallow reservoirs, type II: deep reservoirs in the northern area, type III: deep reservoirs in the southern area ） based on chemical and isotopic compositions. Chemical and isotopic changes of these groups are transitional and reflect the alteration of the seawater trapped in sediments during diagenesis. The type III formation waters, which are characterized by HCO 3 − /Cl − ratio >1 and high δ 18 O values, are strongly affected by the maturation of organic matters and the phase transformation of silica minerals in source rocks around reservoirs. Li ＋ contents of formation waters from the deep reservoirs are less than the seawater and these Li ＋ /Cl − ratios are about the same as the seawater. Also, temperatures of the deep reservoirs calculated using the Mg-Li thermometer are slightly lower than reservoir temperatures. These matters suggest that the formation waters are not affected by fluids migrated from deeper parts. Geochemistry of the formation waters suggests that the oil migration is not related to the formation water in this field.
