Abstract Since the late 1970's, offshore operations have expanded throughout the world in Africa, South America, the Middle East, Asia, and in other areas. Before this, onshore drillings were developed since the end of last century. Restrictions on the petroleum exploration activities around the world ...
Abstract Decommissioning of offshore oil and gas production facilities in California has always been and will continue to be a controversial and hotly debated topic.This Decommissioning has been occurring since the early part of the 20th Century and most recently involved four offshore platforms, a ...
Abstract Noise Pollution continues to receive increasing attention in international level. This paper reviews a growing body of evidence of the harmful effects of man made noise on marine life. There is an urgent need for a European and global legislative framework for monitoring the effects of underwater ...
Abstract Deepwater represents a significant proportion of future oil and gas exploration and production. Scientists have however stated that the deepwater environment is less well understood than the dark side of the moon. At the same time there is increasing pressure from NGOs to postpone deepwater ...
Abstract The aim of the Seismic Survey Environmental Assessment Tool (SSEAT) is to reduce the risks to the environment from seismic surveys. It facilitates environmental impact assessment and the management of environmental sensitivities whilst designing and undertaking a seismic survey. It is both ...
Abstract Movement of cuttings produced while drilling is not a new issue to the drilling industry. We do however see the overall depth of wells, as well as their inclusion of extended horizontal runs ever increasing. We find the risk of differential sticking, excessive loss of pressure, and general ...
Abstract Samples of different fish species were obtained at different sites in the North Sea, Bank of Halten and NW of the Faroe Islands and analysed by GC/MS for selected hydrocarbons. Petrogenic contamination of different origin was observed in almost all samples. Tainting, by organoleptic analyses ...
Abstract Acoustic monitoring of small cetaceans (harbour porpoises and dolphins) has been conducted around two platforms in the central North Sea. At one platform, there was continuous drilling activity while at the other platform, drilling did not occur during the monitoring period. The objective was ...
Abstract Traditional slickline work usually encompasses basic mechanical manipulation for downhole intervention work. In the recent past, a variety of battery-powered downhole tools have emerged in the market, providing additional deepwater solutions for the industry. These tools include the extended-reach ...
Abstract Tunu is a gas field located in the eastern part of Mahakam Delta, EastKalimantan, Indonesia. The field has been produced by TotalFinaElf E&PIndonesie since 1984 in the sensitive ecosystem. The other main activities inthe delta are shrimp farming and fishing activities. The delta is of economicalimportance ...
Abstract Should future regulation of the use and release of E&P chemicals offshore focus more on tests of chronic effects at low levels of contamination, in line with recent ecotoxicological discoveries? Within this context, what groups of E&P chemicals are relevant, and what kind of effects and test ...
Abstract In these times of record operating costs, stakeholders place paramount importance on avoiding unnecessary, unproductive trips in the well. In well intervention applications such as milling, cutting, washing over and casing exit work, the lack of accurate information about downhole conditions ...
Proposal To many, the offshore production facilities punctuating the skyline are probably seen as something of an eyesore. However, the divers who have viewed these structures beneath the waves realize that they provide the foundations for a well-established marine ecosystem. The Platform Environmental ...
Abstract The regulatory body in charge of the North Sea environment is the Oslo Paris Commission, and the key document agreed by the signatory countries is the OSPAR Convention, which came into force in 1998. In June 2000, OSPAR introduced Decision 2000/2, describing a Harmonised Mandatory Control ...
Abstract This paper will examine an unusual intervention case history for a major UK North Sea operator, where a specialised coiled tubing (CT) conveyed mechanical cutter system was used to allow the recovery of stuck drill pipe. Previous to the CT being mobilised to the offshore installation, a number ...
Abstract On the well JACINTO 01 (Angola), by 1 632 m of water depth, while pulling out the BOP stack to check a malfunction during the pressure tests of these BOP, before starting the17""1/2 phase, the breaking of the drilling line, while the BOP was at 620 m, caused the fall of the BOP and about 600 ...
Abstract The fields operated by Esso Exploration and Production Chad Inc. (EEPCI) in a consortium project with PETRONAS and Chevron in Central Africa, target highly unconsolidated sandstone formations. Sand control equipment must be utilized to prevent production of sand resulting in failure of downhole ...
Abstract An environmental impact assessment (EIA) of electromagnetic (EM) survey techniques used for oil and gas exploration in the marine environment was completed and published in November 2011. The EIA was funded by the member companies of the International Association of Geophysical Contractors ...
Abstract This paper aims to provide an overview of leadership aspects needed in developing tri-sector partnerships and therefore, achieving social performance goals of managing social risks that may arise from operations, increase ability to undertake dialogue and promote social initiatives strategically. This ...
Abstract This paper presents a survey of marine toxicity and biodegradability data for surfactants used in the petroleum industry. Surfactants are key chemicals in the formulation of products such as emulsifiers, demulsifiers, dispersants and inhibitors. They are also used directly as foaming and ...
