For many decades, chelating agents have been used successfully as additive in the oil and gas industry, for example during scale removal, iron control and matrix stimulation. More recently, these chemicals have also been used as standalone fluids for the same applications. However, the traditional chelating ...
This paper presents the findings of a study into the impact of reservoir flow behaviour on both the scaling risk at production wells, and the options for managing this scaling risk, for a deepwater sandstone reservoir in the Gulf of Mexico. One significant feature in this field is that flow takes place ...
Xanthan gum and other naturally obtained polymers have been used extensively in the petroleum industry as a “viscosifier” in drilling, completion, workover and hydraulic fracturing fluids. Other than the effects of shear rate, pH and temperature, the performance of various polymers can be greatly affected ...
Multi-stage ‘plug & perf’ operations in the Bakken formation are conventionally performed using pump down perforating or coiled tubing, but when a restricted casing ID, coupled with poor road conditions, strict budget considerations and severe time constraints prevented the use of conventional methods, ...
Total E&P Indonesia West Papua (TEPI WP) has been awarded the Southwest Bird`s Head block covering 7,176 km2 of area straddling the Salawati and Berau/Bintuni basins and situated both in swamp and offshore at water depth up to 30 m off the coast of West Papua, Indonesia. A well exploration drilling ...
The Al Shaheen oil field is located approximately 80 km north-east of Qatar in the Arabian Gulf. It is the largest offshore oil field in Qatar and it is operated by Maersk Oil on behalf of its partner Qatar Petroleum. The Al Shaheen area is a highly productive marine environment due to a combination ...
Summary Sound is increasing in the oceans and noise associated with offshore activities is suspect to having effects (physical, physiological and behavioral) on aquatic life such as marine mammals, reptiles, fish and invertebrates. These animals may be affected at various levels (physically or behaviorally) ...
In what is being called the first Oil and Gas “Sustainable Commissioning” project, advanced composite abrasives (ACAs) is being used to help conserve precious resources. A recent field study and project conducted by Odebrecht commissioning manager, Bernardino Nilton do Nascimento revealed key points ...
Hydrate formation is a major flow assurance issue in the production of oil and gas fields. Kinetic hydrate inhibitors (KHI) act as anti-nucleating agents and delay the formation of gas hydrates. These chemicals are more economical than the thermodynamic inhibitors and are added at a low dosage without ...
Abstract This paper describes the main objectives and early achieved results from the MARENOR project. MARENOR is financed by the Research Council of Norway as well as Norwegian industry partners from oil and gas (EM survey company EMGS), fisheries (shipping company and shrimp trawler Remoy), positioning ...
ABSTRACT The environmental fate characteristics of industrial biocides used in oil and gas applications are of increasing concern due to the industry’s drive for sustainable best practices and regulatory pressure on water use and disposal. A detailed understanding of the environmental impact of biocides ...
ABSTRACT Reservoir Souring is the unplanned production of increased concentrations of hydrogen sulfide (H2S) in wellstream fluids from production wells that are subjected to water-injection. The consequences of souring with respect to safety, corrosion and environmental risk can be significant. This ...
Abstract Bream Field, in Australia’s Gippsland Basin, was originally developed in 1987 as a thin oil column development with gas cap re-injection. A satellite platform was installed in 1996 to capture resource not reachable from the original platform. After achieving 68% recovery, oil rates had ...
Abstract The Manifa field development is a megaproject, the world’s largest offshore hydrocarbon production increment built in a single phase. Manifa is the world’s largest extended reach oil project (2/3 of project’s 350 wells are extended reach wells). Manifa’s rare species, its marine life in shallow ...
Abstract Integrated Natural Gas Liquids/Nitrogen Rejection Unit (NGL/NRU) technology will be utilised for the first time in Qatar on the Barzan Gas Project, which is a joint venture project between Qatar Petroleum (QP) and ExxonMobil Barzan Limited. The North Field Reservoir, which supplies the Barzan ...
Abstract Reliably and responsibly meeting global energy demands is often a challenge involving a delicate balance between environmental stewardship and operational excellence. One such challenge involves the protection of the delicate Arabian Gulf coast ecosystem while developing an enormous hydrocarbon ...
Swarm Intelligence (SI), modelled upon the behaviours of various swarms of animals and insects such as ants, termites, bees, birds, fishes, fireflies, etc. is an emerging area in the field of optimization. SI based algorithms are proclaimed to be robust and efficient optimization tools. This fact is ...
While labeled data is expensive to prepare, ever increasing amounts of unlabeled data is becoming widely available. In order to adapt to this phenomenon, several semi-supervised learning (SSL) algorithms, which learn from labeled as well as unlabeled data, have been developed. In a separate line of ...
A response of the engineering profession to the challenges of security, poverty and underdevelopment, environmental sustainability, and native cultures is described. Ethical codes, which govern the behavior of engineers, are examined from a historical perspective linking the prevailing codes to models ...
This book outlines the basic principles of creation and maintenance of taxonomies and thesauri. It also provides step by step instructions for building a taxonomy or thesaurus and discusses the various ways to get started on a taxonomy construction project. Often, the first step is to get management ...
