Abstract The increasing globalization of industry has brought new challenges and new opportunities to risk communication practitioners, especially those working in Southeast Asia. Unocal's operations in Thailand including a network of nearly 80 platforms in the central Gulf of Thailand provide ...
Abstract A new application for downhole data acquisition provides real-time wellbore intervention optimization via measurement-while-drilling (MWD)-based technologies to enhance pipe-conveyed wellbore intervention operations. This paper discusses the incremental challenges of conventional fishing methods ...
Abstract Stuck pipe has been identified as the largest single contributor to non-productive drilling time. The use of resonant vibration as a means of freeing stuck tubulars from a well bore has been demonstrated to be effective in both Drilling and Workover environments and has the potential to provide ...
Abstract Surface sediment samples were collected from five platforms in the Gulf of Mexico during the Gulf of Mexico Offshore Operations Monitoring Experiment (GOOMEX), a Minerals Management Service funded study, and analyzed for total mercury. While this study was reported in 1995, new interest in ...
Abstract This paper will address and discuss the planning and operational challenges encountered in non-routine wellwork operations / well interventions in ExxonMobil Exploration and Production Malaysia Inc. (EMEPMI) oil and gas fields off the east coast of Peninsular Malaysia. The introduction will ...
Abstract In the course of a recent investigation on the formation damage associated with HEC gels, we found no published comprehensive work on the interactions between HEC gels, the geochemistry of the formation, and the gel breakers. Recognizing this lack of information and in view of the popularity ...
Abstract Coil tubing is a single string of pipe, which can intervene into wells and perform specific jobs without mobilizing a rig. The basic applications are cleaning wellbore/perforations, stimulating selective zones, controlling wells, milling/drilling cement/tools/fish downhole, conveying tools ...
Abstract Over the past decade, potential impacts from anthropogenic sound in the marine environment have received increased attention. The oceans are home to a diverse ecosystem and serve competing uses such as marine habitat, mineral resource operations, shipping, fishing, tourism and recreation. ...
Abstract This case history describes planning and execution of a deep relief well operation that resulted in re-entering, killing and abandoning a wellbore which was blowing in the subsurface. In 1994, a gas exploration well, Makarem, was sidetracked past a bottomhole assembly, which had become stuck ...
Abstract During the last decade significant research has been performed on the possible impact of seismic surveys on marine life. Both fish and marine mammals have been studied. None of the studies have documented direct damage caused by the signals, but there may be a temporary behavior change out ...
Abstract This paper describes a new intelligent well intervention performance system. One that contains a variety of sensors and electronics to gather critical downhole measurements, analyze them, and transmit them to surface for viewing in real time. It confirms that many well intervention operations, ...
Accidental and short-term oil pollution, while troublesome, expensive, and locally damaging, appears not to have a permanent effect on the ecosystem. On the other hand, in unstable marshlands and shallow-water embayments, industrial activity such as mineral exploration and production can be quite destructive. Introduction Oil ...
Abstract After several decades of use, resistivity, formation density and neutron porosity measurements are considered fundamental to formation evaluation. In the last decade, logging-while-drilling (LWD) formation density and neutron porosity tools utilizing chemical radioactive sources have been ...
Abstract The scenario of having drill string or work string cemented up in plugging or squeezing operations is a real occurrence and if the right procedures are not followed, then the intervention process can be lengthy, time consuming with increased costs to the operator. The intervention techniques ...
Abstract The 1993 U.S. Environmental Protection Agency (EPA) Gulf of Mexico General Discharge Permit (GMG290000), required operators to conduct an offshore produced water bioaccumulation study. The goals were to assess the potential for bioaccumulation to marine organisms of selected target compounds ...
Abstract Most oil and gas installations produce significant quantities of associated water which has to be disposed of. Offshore, produced water (PW) is often discharged in the sea, after treatment. Impact of such discharge on the marine environment is a concern in the North Sea, due in particular ...
American Institute of Mining, Metallurgical, and Petroleum Engineers, Inc. This paper was prepared for the SPE-European Spring Meeting 1976 of the Society of Petroleum Engineers of AIME, held in Amsterdam, The Netherlands, April 8-9, 1976. Permission to copy is restricted to an abstract of not more ...
Abstract The Incoloy Alloy 925 flapper from a damaged tubing retrievable safety valve (TRSV) was blown downhole using a wireline conveyed cannon. A downhole video survey revealed the flapper to be deformed but intact, lodged above a PBR at 11,902 ft md RKB. Attempts to fish the flapper were unsuccessful ...
Abstract Petronas Carigali Bahrain Ltd (PCBL) drilled two exploration wells in the shallow water environment offshore Bahrain in 2003. In order to protect the rich and sensitive natural environment with commercial and scientific importance due to the presence of a number of unique and rare habitat ...
Abstract As well complexity increases, re-entry and intervention operations are becoming increasingly ambitious in both their objectives and their risk profile. At the same time, intervention and service tool operating parameters downhole are traditionally controlled by making surface adjustments based ...
