... the plant. These hours then serve to assist in the sizing of demolition teams. Decommissioning teams have been sized such that the decommissioning takes a maximum of 90 days. Similarly the well abandonment crews are sized to effect a quick shut-in of the wellheads, and the preparation, cutting...

... ABSTRACT North Sea environmental legislation imposes limits on the amount of oil on cuttings (OOC) discharged to the marine environment when using oil-based drilling fluids. This paper presents the laboratory development by International Drilling Fluids (IDF) of a conceptually new type of oil...

... ABSTRACT This paper presents the results and implications of a research project * to study, under controlled laboratory conditions, the influence of oil based mud physical properties and chemical composition on the quantity of oil retained on cuttings. Substrates, representing common rock...

..., initial results show that significant improvements in cuttings cleaning efficiencies over existing wash fluids have been confirmed in both types of full-scale hardware even though this hardware has not been specifically optimised for K5T. See Table 4 for examples of results. TABLE 4 PRELIMINARY...

... Abstract A description is given of a single-cutter tester for studying the cutting process of PDCs in rock under simulated downhole conditions. The use of the tester is illustrated by a study of the effect of downhole pressures on the cutting process in shales. Prior to the tests the Pierre...
