Eocene and Lower Oligocene rocks are potential source rocks for crude oil accumulations in the Hungarian Palaeogene Basin. To enhance the understanding of the hydrocarbon system, this study (i) assesses the petroleum potential of Palaeogene…
In the Beijing-Tianjin-Hebei region, there is a huge gap in the capacity of natural gas peak regulation. Due to the influence of fault development and complex structure in Jizhong Depression, the evaluation of fault sealing ability is the top…
The dissolution of fine particles into flowing and stranded fluids is not only one of the most prominent formation damage problems but also, is prejudicial to economic viability of oil-bearing matrices. To this end, the present paper investigates the…
The current problem of the last decade in the world is the increase of oil production volume due to the extraction of its hard-to-recover reserves. The difficulty of its extraction is determined not only by the petro-physical characteristics of the…
CNOOC has been involved in a pilot study to determine the efficacy of Organic Oil Recovery (OOR, a unique form of microbial enhanced oil recovery) as a means of maximising oil recovery from its Scott field. CNOOC s operated Scott asset came on stream…
This paper outlines the systematic approach adopted in carrying out post-production fluid content andcontact analysis in a mature Niger Delta field with more than 50 years production of oil and gas in multi-stacked reservoirs with varying fluid…
Coalbed methane, shale gas and tight gas within coal measures exist simultaneously in many basins worldwide, with the successful exploration and development of specific gas respectively. However, the multi-layer/multi-unconventional natural gas…
The petrophysical evaluation of the Titas gas field (Titas-15) has been carried out for its reservoir characterization and to quantify the reservoir hydrocarbon prospects and gas productivity. The Quick Log Analysis Tool (QLAT) of PE2 Essentials…
The Sulige Gas Field in the Ordos Basin ranks the first in China in terms of reserve scale and annual gas production of tight sandstone gas reservoirs. In order to further extend the stable production time and enhance the recovery factor of tight…
To better understand gas migration and accumulation in tight sandstone reservoirs, we conducted an integrated petrographic and geochemical analysis of hydrocarbon and aqueous fluid inclusions. This analysis was combined with the burial and multistage…
As an unconventional, clean energy resource, natural gas hydrate is abundant and widely distributed in the subsea and permafrost area. Since the 1990s, permafrost and ocean hydrate production tests have been conducted successively by Canada, the…
Carbonate reservoirs represent a steadily growing part of sedimentary formations targeted for oil and gas exploration worldwide. It is currently evaluated that over 50% of the remaining conventional hydrocarbon reserves are in carbonate formations.…
Robust inferences on understanding the reservoir heterogeneity and processes of the respective petroleum system are essential to reduce risks throughout the petroleum exploration and development phases. In this paper we present integrated static…
The newly discovered Halahatang oil field in the northern Tarim Basin has a potential resource of more than 70 billion bbl of oil. Oil organic geochemical data from the Halahatang oil field indicate that the oils are of moderate maturity,…
Engineering and economic optimization of the value of water as an essential commodity and successful management of the overall water cycle are of great interests for the petroleum industry. The general objective is to maximize the benefits and safety…
