There are many challenges associated with development of offshore petroleum fields. Subsea production facilities are increasingly used in the petroleum industry as the technology has matured and quality increased. The use of subsea technology has advantages as well as challenges. Based on a literature review this paper identifies some if the development challenges related to the design and oper...

A large quantity of data in earthquake, well-log, grilling, geology and other non-seismic geophysics, has been accumulated during long period of petroleum prospecting. These data are stored in papery document and managed in low efficient manual management. This paper proposed this petroleum exploration information management system which adopts SQL Server2000 as database server and combines B/S...

This paper empirically explores the concept of co-materialization to explain the digital innovation dynamics in offshore petroleum production. The central insight developed is that the very nature of subsurface processes and phenomena that may be monitored and controlled is transformed as offshore petroleum production is digitalized. The paper shows how digital technologies are intrinsic to thi...

Marine controlled source electromagnetic (MCSEM) surveys have become an important part of offshore petroleum exploration. In this paper we present a new approach to 3-D inversion of MCSEM data. It is based on rigorous integral equation (IE) forward modeling and a new IE representation of the sensitivity (Frechet derivative matrix) of observed data to variations in sea-bottom conductivity. This ...

In this paper, we present an alarm management system focused on guiding offshore platform operators’ attention to the essential information that calls for immediate action during emergency situations. Due to the imminent associated danger involved in the petroleum operation domain, only well trained workers are allowed to operate in offshore oil process plants. Although their vast experience, h...

(1) A few shipping accidents have caused spectacular local threats to the environment. (2) Leaks in offshore oil well drilling operations have received widespread news coverage. (3) A rising demand for petroleum products throughout the world complicated by political considerations has produced a corresponding expansion in tanker shipping operations and in offshore oil operations, both of which ...
