Integrated Treatment and Disposal of Waste Drilling Fluid Onshore China: Laboratory Investigation and Process Design

Abu Dhabi International Petroleum Exhibition & Conference, 2017
Abstract The traditional methods of treating and disposing waste drilling fluid are encountering severe challenges with the tightening of environmental regulations in China. Commonly used chemical destabilization technology needs to be improved, and treating processes are required to be optimized and updated.

Terrain, Land Use and Waste Drilling Fluid Disposal Problems, Arctic Canada

ARCTIC, 1980
A survey of over 60 abandoned wellsites in the Mackenzie Delta, the Arctic Islands and the interior Yukon Territory indicated that approximately 25% of the sites experienced terrain problems related either directly or indirectly to sumps and/or the containment of waste drilling fluids.

Useful Recycling and Safe Disposal Technology of Waste Oil Based Drilling Fluids and Its Application

International Petroleum Technology Conference, 2013
Abstract Waste oil-based drilling fluids are hazardous wastes containing oil, heavy-metal and organic pollutants. However, the common treatment methods at home and abroad these methods not only waste many useful resources (because the oil is discarded rather than recovered) but also increase the pro-environment cost

Microwave Drying of Drilled Cuttings in the Context of Waste Disposal and Drilling Fluid Recovery

Energy Technology, 2014
AbstractThe use of drilling fluids in oil drilling process generates solid–liquid mixtures that must be separated. One of the aims of this process is compliance with environmental laws regarding to disposal of waste from drilling activities. The present study aims to investigate the microwave drying of contaminated drilled cuttings.

COMPOSITE SORBENTS FOR THE DISPOSAL OF WASTE WATER CONTAINING CUTTING FLUIDS

SCIENCE EDUCATION PRACTICE
The composition of a complex adsorbent based on iron oxides for the disposal of wastewater containing cutting fluids (CF) is proposed. The parameters of utilization with the use of processing in the magnetic field of the suspension are determined. The optimal ratios of the adsorbent to CF have been determined.

Dynamic Programming for Optimal Disposal of Metal Working Industrial Waste Water/Oil/Fluids Mixtures An Overview

SSRN Electronic Journal, 2016
The metal working industries generate different kinds of waste waters as a result of processing metal parts/products, machinery, and other associated activities as well. The performing operations may have two types of activities: (a) manufacturing, and (b) rebuilding or maintenance. Actually, coolants are important component of metal working operations

O and H diffusion in uraninite: Implications for fluid–uraninite interactions, nuclear waste disposal, and nuclear forensics

Geochimica et Cosmochimica Acta, 2011
Abstract Diffusion coefficients for oxygen and hydrogen were determined from a series of natural uraninite–H 2 O experiments between 50 and 700 °C. Under hydrous conditions there are two diffusion mechanisms: (1) an initial extremely fast-path diffusion mechanism that overprinted the oxygen isotopic composition of the entire crystals regardless of ...

U.S. Space Station Freedom waste fluid disposal system with consideration of hydrazine waste gas injection thrusters

26th Joint Propulsion Conference, 1990
The results are reported of a study of various methods for propulsively disposing of waste gases. The options considered include hydrazine waste gas injection, resistojets, and eutectic salt phase change heat beds. An overview is given of the waste gas disposal system and how hydrozine waste gas injector thruster is implemented within it.

Surface Disposal of Waste Drilling Fluids, Ellef Ringnes Island, N.W.T. : Short-Term Observations

ARCTIC, 1985
An experimental procedure by which waste drilling fluids were placed upon the tundra was undertaken at the Panarctic Dome et al. Hoodoo N-52 wellsite on Ellef Ringnes Island during the early winter of 1981-82. Preliminary site investigations indicated ice-rich permafrost condi- tions and the potential for extensive terrain disturbance if a sump were ...

New Facets of Universal Fluid Usage: Reduction of Hole Wash-Out and Solidification for Environmentally Safe Drilling Waste Disposal

Proceedings of IADC/SPE Drilling Conference, 1998
Abstract Two new benefits derived from the use of a Universal Fluid (UF) have been demonstrated:reduction of the hole washout volume andsolidification of excess drilling fluid and drill cuttings for environmentally acceptable on-site waste disposal.
