Effects of Tide and River Discharge on Mud Transport on Intertidal Flat

Journal of Waterway, Port, Coastal, and Ocean Engineering, 2012
Fine-grained sediment budgets based on the monthly bed level and net sediment flux monitoring from October 2006 to October 2007 are estimated to examine the relative contributions of tides and river discharge to mud transport on an intertidal flat adjacent to a river mouth in a semiclosed sound.

Environmental Impact of Oil-Base Mud Cuttings Discharges-A North Sea Perspective

Proceedings of IADC/SPE Drilling Conference, 1983
Abstract Discharges of Oil-Based Mud Cuttings have an environmental impact which is limited in time and in volume/area. North Sea field data (1979-1982) indicates that beyond the immediate neighbourhood of the discharge, the hydrocarbon concentrations in the water column are effectively at ambient levels and environmental impact, if any,

Seafloor Monitoring for Synthetic-Based Mud Discharged in the Western Gulf of Mexico

SPE/EPA Exploration and Production Environmental Conference, 1995
Abstract Synthetic-based muds have been used to simultaneously improve drilling and environmental performance. The fate and effects of synthetic-based mud discharges in the marine environment have been issues of concern with the drilling industry and governmental agencies.

An assessment model for the fate and environmental effects of offshore drilling mud discharges

Estuarine, Coastal and Shelf Science, 2006
Abstract The benthic boundary layer transport ( bblt ) model was developed to assess potential impact zones from drilling mud discharges from offshore oil and gas drilling. The model focuses on the drift, dispersion and concentration levels of the suspended fraction of the drilling mud fines in the benthic boundary layer with the assumption of a ...

Electric discharge machining of AA2024 with specific wt% of red mud hybrid composites

Materials Today: Proceedings, 2021
Abstract Metal matrix composites (MMCs) that find extensive applications in the aerospace, aircraft, rail sector, and automotive industries are very difficult to machine by the conventional methods. So, Electric discharge machining (EDM) is widely used for machining MMCs.

Best Practices for Drill Cuttings & Mud Discharge Modeling

SPE International Conference on Health, Safety, and Environment in Oil and Gas Exploration and Production, 2004
Abstract This document describes data needs for performing cuttings and drilling mud discharge modeling and examples of simple formats for presenting model predictions. The objective is to encourage greater acceptance of discharge modeling as an environmental assessment tool by providing a foundation for consistent modeling study ...

The hydrodynamical characteristics of nearshore waters and the discharging process of mud flats— A case study of the mud flats near Lianyungang, China

Chinese Journal of Oceanology and Limnology, 1987
It is apparent that there is a difference between mud coasts and sand coasts in such aspects as sediment components, hydrodynamics of nearshore waters, and the formative process in configuration, and profile. The intensity distribution of waves affecting the mud flats in Lianyungang, and the conditions determining tidal water levels, are discussed in ...

Environmental Assessment of Synthetic Based Drilling Mud Discharges to Bass Strait, Australia

SPE International Conference on Health, Safety, and Environment in Oil and Gas Exploration and Production, 1998
Abstract Esso Australia Ltd. (Esso) on behalf of the Esso/BHP joint venture undertakes exploration and development drilling activities to produce oil and gas from the Gippsland Basin in eastern Bass Strait. As part of the environmental management of the operation, a field monitoring program was undertaken to verify the predicted ...

Field verification of the Offshore Operators Committee (OOC) Mud and Produced Water Discharge Model

Environmental Modelling & Software, 2004
Abstract This paper describes the use of field data on drilling mud and produced water dispersion to verify the Offshore Operators Committee (OOC) Mud and Produced Water Discharge Model (the “OOC Model”). Field studies for produced water and water-based drilling mud discharges provided data on effluent properties, discharge rates and pipe diameters ...

New Oil-Base Mud Additive Reduces Oil Discharged on Cuttings

SPE/IADC Drilling Conference, 1991
ABSTRACT A new additive reduces the amount of oil retained on drill cuttings generated by drilling with an oil-base fluid. The oil retention on drill cuttings phenomenon and the approach used in dealing with it in the field are reviewed with particular emphasis on the use of high water content oil-base muds.
