Abstract Reactive mud cake breaker fluids in long open hole horizontal wells located across high permeability sandstone reservoirs has had limited success because they often induce massive fluid losses. The fluid losses are controlled with special pills, polymers and brine or water, causing well impairment ...
Abstract This paper presents a case history on drilling of an ultra-deep exploratory well with a lot of problems and final solution in a complicated K structure in Uzbekistan. Drilling troubles include serious stuckpipe resulted from drilling-in the unexpected high pressure brine formation, malfunction ...
Abstract A robust chemical product comparative scoring process (CSP) has been developed that facilitates continuous improvement in human and environmental hazard reduction. The method is simple and quick enough to use during development of new products, is adaptable to changing needs and visually ...
Abstract Environmental qualification of chemical products is a critical component of the oil and gas industry. However, regulatory and chemicals evaluation criteria, if available, are typically designed for local ecosystems and vary within specific regions and regulatory entities. Although some qualification ...
Abstract Both oil- and water-based fluids have been used to drill in the Fayetteville shale play with mixed results. Oil-based muds (OBM) provide reliable inhibition and drilling performance, but environmental and economic concerns have generated interest in water-based alternatives. However, drilling ...
Abstract When newly drilled oil and gas wells fail to reach the expected production levels, near-wellbore damage may have resulted from fluid incompatibility, poor fluid/rock interaction and/or mechanical damage. These problems may also occur during remediation or stimulation operations, if the treatment ...
Abstract In the last decade, high salinity waterflooding has been emerged as a prospective EOR method for chalk reservoirs. Most recently, Saudi Aramco reported significant increase in oil recovery by low salinity waterflooding in Saudi Arabian carbonate reservoirs. Understanding of the mechanisms leading ...
Abstract Water is a key element in oil and gas operations. Many operations need and/or are performed most ideally with fresh water, but its availability is decreasing in some locations around the world. One area of particular concern is offshore operations to stimulate carbonate formations. Acid stimulation ...
Abstract An operator was planning to drill the first horizontal well in the Inhassoro field in Mozambique. The type of completion would be an open hole utilizing expandable screen technology. The formation had highly reactive shale stringers necessitating the use of an inhibitive fluid, but due to the ...
Abstract In a deepwater West African field the relatively small number of high-cost, highly productive wells, coupled with a high barium sulfate scaling tendency (upon waterflood breakthrough of injected seawater) requires effective scale management along with removal of near-wellbore damage in order ...
Abstract Recently, eighteen high profile corporate crises or major risk events of the last decade and their origins, impact & implications have been analysed. Seven underlying types of risks are integral to the ethos, safety, reputation and longevity of a business and its ability to use its own ...
Abstract In 1996, four offshore oil and gas platforms were removed from the Santa Barbara Channel off the coast of Santa Barbara, California. The four platforms, Heidi, Hope, Hazel, and Hilda, (collectively the 4H platforms) were installed between 1958 and 1965 and provided oil and gas production until ...
Abstract During its recovery from war and the development of infrastructures, Angola has relied on the income from the oil industry to support the increasing demands for the reconstruction of its infrastructure and economy. The rapid growth of the oil industry in Angola was accompanied by a greater ...
Abstract While water-based fluids are generally preferred for drilling in environmentally sensitive locations, many are formulated with potassium chloride (KCl) to achieve good inhibition of reactive clays. The chloride ion however can be defined as a contaminant in land operations, with the potential ...
Abstract Modern Oil and Gas facilities are designed to meet an extensive array of government legislation and international standards and are subjected to a range of technical and operational safety reviews and analysis to identify and reduce failure risk. By taking such an approach, residual risks ...
Abstract Extractive industries face two main challenges in terms of CSR and poverty reduction: 1) recognize that societal activity is part of their core business; 2) take part in socio-economic projects that contribute to their stakeholders' empowerment and not only to their living conditions. Based ...
Abstract The Nord Stream Project ("the Project??) comprises two 48?? sub-sea pipelines (the longest in the world so far) and landfalls in Russia and Germany, and is currently Europe's largest infrastructure project. The 1 224 km long offshore pipelines will together carry 55 billion cubic metres ...
Abstract Occupational health and safety is a critical multidisciplinary and multifaceted component of the oil and gas industry. Evaluation of job-specific occupational health and assessment of the risks associated with each job profile are conducted across the globe. Nevertheless, healthcare providers ...
Abstract Total E&P Indonesie (TEPI) has been operating for more than 40 years in Mahakam Contract Area located at Mahakam Delta, Kutai Kartanegara District, East Kalimantan Province, Indonesia, despite the local environmental and social challenges. Mahakam Delta was initially covered with dense ...
Abstract The current paper provides a narrative of the Health Impact Assessment (HIA) of a greenfield project located in a remote part of Papua New Guinea. HIA, in the context of this project, is presented as one of the processes that a company needs to go through in order to develop a site-specific ...
