Abstract This paper presents a summary of the strategy and execution for intersecting and plugging at a depth of 2730m a significant water cross flow (10000-15 000m3/day) invading a depleted sour gas producer well. This operation was performed at the beginning of 1997 in the south west of France. To ...
SPE Member Abstract Case histories of 22 treatments with a very new sand control procedure applied in Oryx Energy Company wells are reviewed. An acid curable resin is positioned in the casing across the perforated interval in an incompetent sand formation. A gas-frac propellent tool is placed in the ...
Abstract The use of floating production systems ( FPS ) in offshore oil and gas developments is proliferating around the world. The Zaafarana Oil Field, which was discovered in late 1990 is located in approximately 60 meters of water, 7 kilometers off the west coast of the north Gulf of Suez, Egypt. ...
Abstract The Kinabalu Drilling Alliance is named Puncak Jaya. Puncak is Bahasa Malaysia for peak, and Jaya is success, thus Puncak Jaya translates as the Summit of Excellence. The evolution of incentive contracting in SSB/SSPC has seen the introduction of simple bonus and penalty schemes in services ...
Abstract Seven producer wells (oils between 32-36 ºAPI) from Basal Salina fm. in Providencia and Lobitos areas of Z-2B Block (Talara basin, Northwest Peru) were selected to evaluate a biotechnology approach for Enhanced Oil Recovery. The MEOR candidates are vertical and high-angle slanted wells. They ...

Abstract Both Saudi Aramco and Total Indonesia found benefits in selecting 4 in. drill pipe with streamlined double shoulder connections for the drilling of wells, for which the 3 1/2 in. drill pipe was ...
The pdf file of this paper is in Russian. To purchase the paper in English, order SPE-102123-MS. Abstract Redevelopment of mature oil fields is becoming increasingly important in Russia and worldwide. An extensive application of new ideas, coupling reservoir management and production enhancement of ...
Background This study was designed to determine whether advanced non-small-cell lung cancer (NSCLC) patients with high copy number of epidermal growth factor receptor (EGFR) can benefit from treatment with EGFR-tyrosine kinase inhibitors (TKIs). Methods EGFR gene copy number was assessed by fluorescence ...
There are many studies dealing with the protection or restoration of wetlands and the sustainable economic growth of cities as separate subjects. This study investigates the conflict between the two in an area where city growth is threatening a protected wetland area. We develop a stochastic cellular ...
Through the history of ecology, fluctuations of populations have been a dominating topic, and endogenous causes of fluctuations and oscillations have been recognized and studied for more than 80 years. Here we analyzed an historical dataset, covering more than 130 years, of European lobster (Homarus ...
Background Early evolutionary theories of aging predict that populations which experience low extrinsic mortality evolve a retarded onset of senescence. Experimental support for this theory in vertebrates is scarce, in part for the difficulty of quantifying extrinsic mortality and its condition- and ...
Marine reserves are an effective tool for protecting biodiversity locally, with potential economic benefits including enhancement of local fisheries, increased tourism, and maintenance of ecosystem services. However, fishing communities often fear short-term income losses associated with closures, and ...
Disaster recovery after the Indian Ocean tsunami in 2004 led to a number of challenges and raised issues concerning land rights and housing reconstruction in the affected countries. This paper discusses the resistance to relocation of fishing communities in Chennai, India. Qualitative research methods ...
The population of flesh-footed shearwaters (Puffinus carneipes) breeding on Lord Howe Island was shown to be declining from the 1970's to the early 2000's. This was attributed to destruction of breeding habitat and fisheries mortality in the Australian Eastern Tuna and Billfish Fishery. Recent evidence ...
The reefs surrounding the Gilbert Islands (Republic of Kiribati, Central Pacific), like many throughout the world, have undergone a period of rapid and intensive environmental perturbation over the past 100 years. A byproduct of this perturbation has been a reduction of the number of shark species present ...
There will be winners and losers as climate change alters the habitats of polar organisms. For an Adélie penguin (Pygoscelis adeliae) colony on Beaufort Island (Beaufort), part of a cluster of colonies in the southern Ross Sea, we report a recent population increase in response to increased nesting ...
Freshwater (FW) fishes actively absorb salt from their environment to tolerate low salinities. We previously reported that vacuolar-type H+-ATPase/mitochondrion-rich cells (H-MRCs) on the skin epithelium of zebrafish larvae (Danio rerio) are primary sites for Na+ uptake. In this study, in an attempt ...
Species’ ecology and evolution can have strong effects on communities. Both may change concurrently when species colonize a new ecosystem. We know little, however, about the combined effects of ecological and evolutionary change on community structure. We simultaneously examined the effects of top-predator ...
Ocean acidification represents a threat to marine species worldwide, and forecasting the ecological impacts of acidification is a high priority for science, management, and policy. As research on the topic expands at an exponential rate, a comprehensive understanding of the variability in organisms' ...
The reproductive biology of albacore tuna, Thunnus alalunga, in the South Pacific Ocean was investigated with samples collected during broad-scale sampling between 2006 and 2011. Histology was done in a single laboratory according to standard protocols and the data analysed using generalized linear ...
