Abstract An Environmental Risk Analysis (ERA) was conducted as a pilot study on the Dalia Total FPSO (Floating Production and Storage unit) in Angola located at about 135 km off the coast with complex subsea installations at 1400m depth. The environmental damage and its frequency resulting from the ...
ABSTRACT : In 137' of water depth, F-10 platform with 12 piles and 8 slots was built in 1966 by COPE to exploit the North-Western part of the Field, (16 km., of Sinai shore and 150 km South of Suez). By June 1967, one well was drilled to 8974 ft. and completed as oil producer. After June 1967, ...
Abstract In the process industries, hazardous materials can be released accidentally as vapor, gas or liquid and are dispersed in the atmosphere. Ammonia is one of the most extensively used industrial chemicals. It is highly soluble in water and has toxic and corrosive effects caused by its alkalinity. ...
Abstract Historically, the applications of window milling tools and methods were limited to remedial operations. The main bore would be sidetracked only in the event of irretrievable fish, collapsed casing, depleted reservoir, etc. In recent years however, the re-entry drilling has become an increasingly ...
Abstract Waste of Naturally Occurring Radioactive Materials (NORM) poses a challenge to operators and authorities alike. The paper reviews legislation and practices regarding NORM waste management in the North Sea countries, with emphasis on the potential environmental impacts. The paper gives an ...
Abstract Recently a contaminated cement squeeze was performed in the Gulf of Mexico using coiled tubing. The work was performed at 18,600 ft, 326°F bottom hole temperature, 12,000 psi pumping pressure and 9,000 psi chokeback pressure in a H2S, CO2 environment. Operationally this squeeze was a tremendous ...
Abstract Testing of drilling fluids and new additives before use offshore has become a common practice in the United States, Canada, and Europe. Standards for testing these systems vary depending on the concerns and perspective of each country. Testing within a country can also vary between regions. ...
Abstract This paper discusses a technique for the completion and servicing of oil and gas wells while under pressure which can prevent formation damage caused by exposure to kill fluids. Operational procedures and actual field examples of completions and workovers performed with this technique are ...
ABSTRACT Brunei Shell Petroleum offshore well A was offline and shut in due to the 3 1/8"" 5K lower master valve on the monoblock tree, being seized in the closed position, due to scale production. The subsequent loss of production was 200 m3 (1260 BOPD), with a monetary value of US$1.5 million per ...
Abstract The London Convention, which regulates dumping at sea on a global basis has recently approved a substantial change in its operational processes with the adoption of a Waste Assessment procedure. This new procedure replaces the traditional substance based approach which had been in operation ...
Introduction During the past 25 years huge investments have enabled the development of a very busy offshore industry in the North Sea area. International environmental policy regulations for this type of activity are given by the Paris Commission and by International Conferences on the Protection of ...
Abstract Drilling deeper wells with high angles are becoming the norm in the Gulf of Mexico. As time passes these wells require some type of intervention. Coiled tubing intervention being an economic option creates new challenges by pushing existing coiled tubing technology to its limits. Deeper holes ...
Abstract This paper outlines the environmental management controls successfullyimplemented during the construction of two offshore mini-platforms andassociated pipelines located in environmentally sensitive shallow tropicalmarine waters in the North West Shelf area of Western Australia. The innovative ...
Abstract In 1994, the International Association of Oil and Gas Producers (OGP) issued a report on the fate and effects of constituents produced water in the marine environment, based on information from member companies and the literature (1). The report, which focused on the North Sea, was reviewed ...
Abstract This paper describes the reason of sidetracking in 26 inch hole of Salman field in Persian Gulf, its problems and restrictions including unconsolidated formation type, existence of washout below the conductor pipe, probability of anti collision , limitation to survey in order to determine ...
Availability of Surface Water It is estimated that the water demands of an oil shale industry of about 1.5 million bbl/day as well as the water demands of the associated growth, could be satisfied from surface supplies without having to significantly reduce other existing or projected consumptive uses ...
Abstract Determination of the potential of surfactants to bioaccumulate in marine species has long been problematic in the chemical hazard and environmental impact assessments performed for offshore operations. Recently, this issue has become increasingly significant as regulators have invoked the ...
Abstract West Lutong is a mature field with 8 rounds of field development campaigns and close to 40 years of production. Currently, only 50% of total strings are flowing. However, the idle wells could possibly access undeveloped marginal reserves in shallow reservoirs. These shallow reserves are located ...
Abstract Well completions for tension leg platforms require special consideration in key areas. Standard downhole equipment including subsurface safety valves can be used in a conventional manner from TLP's. Special designs, however, may be required for annular safety systems or sales risers. Introduction Future ...
Abstract This paper presents three case histories that demonstrate the successful useof coiled tubing (CT) to convey tubing-conveyed perforating (TCP) guns underdiverse well conditions and applications. The deployment of this type of gunwith coiled tubing is commonly referred to as CTCP. The three ...
