The existing volumetric approach was honored by considering the effects of oil and gas saturations on the evaluation of geothermal resources in oil and gas reservoirs. The main reason to do so was that oil and gas phases may not be simply substituted by water because the values of the specific heat of oil and gas are smaller than that of water. We selected an oil reservoir, Hexiwu, from Huabei ...

large and complex infrastructure projects involve various risk factors and successful implementation of such project depends on effective management of the key risk factors. this paper reviews the literature to identify essential risk variables associated with infrastructure projects. base of these risk variables and case studies of same projects, a survey is conducted to isolate and assess the...

The University of Agder, Norway, has recently founded a Centre for Integrated Emergency Management (CIEM). The centre brings together a highly multi-disciplinary group of local and international researchers in technology and the social sciences. This paper presents an interdisciplinary vision for large-scale integrated emergency management that has been inspired by the transition from platform ...

Microscopic oil displacement of water flooding and sweep efficiency of continuous gas injection could be improved by water alternating gas (WAG) injection. The WAG injection process aims to squeeze more oil out of the reservoirs; in this method, water and gas are alternatively injected into the reservoir. Also, availability of hydrocarbon or CO2 gases in the field makes it attractive for gas-ba...

During tertiary miscible gas injection direct contact between gas and oil can be prevented by water surrounding residual oil. The principal aim of our study is to assess the importance of this waterblocking phenomenon in multicomponent gas injection. We study this process using a multicomponent porescale model. Light components in the gas dissolve in the water and diffuse through the water to r...

Oil and Gas Pipeline (OGP) projects face a wide range of safety security Risk Factors (RFs) globally, particularly in the oil gas producing countries having insecure environment poor records. Inadequate information about causes pipeline failures knowledge OGP hinder efforts mitigating such risks. This paper, therefore, aims to develop risk management system that is based on holistic approach id...

Delays in completing the construction of oil and gas projects impact production, sustainability, reliability, revenues company, which result market share losses long term. This research aimed to determine, evaluate, rank root causes schedule delays pipeline Saudi Arabia. Forty-seven different were identified firstly from a wide-ranging literature review then finalized through conducting intervi...
