Abstract Fisheries are an important resource for communities neighboring Chevron operations in Cabinda, Angola. Threats to these resources can affect local food supplies and economic well-being. Real or perceived impacts from oil and gas operations can create tensions and damage reputation and harm ...
Abstract New technology has been introduced to allow completion of the wireline logging program after the tool string has become lodged in the wellbore. Charges associated with extracting a stuck tool are substantial. These charges result from the nonproductive time during the fishing trip, an associated ...
Abstract In coiled tubing conveyed through-tubing fishing operations, conventional jarring technology often creates limitations due to the requirement to repeatedly cycle the coiled tubing over the gooseneck in order to actuate and re-cock the jar. It is well known and documented in our industry that ...
Abstract Wellbore obstructions are a common dilemma and typically must be removed as they can severely restrict a well's production capability and have proven to be very costly. For instance, scale formation will eventually result in lower yields and well failure, while a fish left in a well can ...
Abstract The boom in horizontal drilling presents new problems that require innovative solutions. Typical drilling problems such as stuck drill pipe have only become more acute with the emergence of horizontal drilling. Formation instability, improper hole cleaning and break-out debris in the hole ...
Abstract HP/HT gas wells, especially those in South Sumatra, Indonesia, present many challenges to exploitation operations due to a 408°F bottomhole temperature, a 10,500psi bottom hole pressure at some 11,000ft, and sour gas components of 34% CO2 and 100 - 200ppm H2S. During the final stages of the ...
Abstract Good well and reservoir management practices demand that new gas wells be tested to expected potentials at the onset of production and build up surveys carried out at specified intervals during the life of the well. This will help to determine the deliverability of the wells, obtain base ...
Abstract The Piceance Creek field is a high pressure gas field located in the northwest corner of Colorado and production is from multiple zones at depths in the order of 12,000ft. Standard well construction in the field takes the form of monobore completions with several sets of perforations producing ...
Abstract In the last decades the ecological role of off-shore platforms as a suitable habitat for fish species has been acknowledged in the context of marine conservation and investigated by an increasing number of studies. Fish communities associated with these artificial structures have been analyzed ...
Abstract The Oropendola Field is located in the Llanos Basin of Colombia and production from the wells is typically augmented by means of artificial lift methods, particularly the jet pump. During a recent routine wireline campaign to install a jet pump in a sliding sleeve, difficulty was experienced ...
Abstract Coiled tubing use in the Western Operating Area of the Prudhoe Bay oil field in the Alaska Arctic increased to over 750 operations in 1989. Coiled tubing is routinely used to run inflatable bridge plugs and packers, and electric line logging tools plugs and packers, and electric line logging ...
Abstract One of the challenging and costly situations to overcome in modern day directional drilling applications is stuck bottom hole assemblies (BHAs) and other tubulars due to differential and/or mechanical sticking forces. Chances of recovery decay with time and conventional fishing BHAs are ...
Abstract Improved coiled tubing (CT) technology, development of specially-designed hydraulically-actuated service tools, and increased emphasis on cost efficiency have made coiled tubing a viable option for many fishing jobs. Before the emergence of coiled tubing fishing technology, traditional service ...
Abstract Any object dropped or stuck in a well that interferes with it's normal operations is called a fish and must be removed from the well. The operation of removing these objects is called a fishing job. When we are involved in a fishing job, we simply say ""We are fishing"". Why or when these ...
Ocean acidification, a decrease in the pH in marine waters associated with rising atmospheric CO2 levels, is a serious threat to marine ecosystems. In this paper, we determine the effects of long-term exposure to near-future levels of ocean acidification on the growth, condition, calcification, and ...
Gig2 (grass carp reovirus (GCRV)-induced gene 2) is first identified as a novel fish interferon (IFN)-stimulated gene (ISG). Overexpression of a zebrafish Gig2 gene can protect cultured fish cells from virus infection. In the present study, we identify a novel gene family that is comprised of genes ...
ABSTRACT The PNG LNG Project has established a Community Development Support Plan (CDSP) with the purpose of mitigating potentially harmful effects and promoting the development of conditions conducive to enhancing the livelihoods of communities in the Project Impact Area (PIA). The CDSP provides for ...
Abstract In late 2011 the Queensland State Government of Australia declared the Cooper Creek Basin in South West Queensland to be a Wild River Area under the Wild River Act 2005. The Wild River Area covers a significant proportion of Santos' current tenements and future development interests in ...
Abstract Introduction Strong LNG demand, both here in Australia and overseas, fuelled by worldwide transition to a low carbon economies is driving unprecedented growth in coal seam gas (CSG) exploration and development of east coast resources, not to mention the other conventional gas resources around ...
