In an ideal borehole and mud system, cuttings would be transported to surface with the same order and composition as they were cut, as in Figure 1. In reality, it is commonly observed that, no matter how sharp a drilling break or clearly defined a formation top on an electric log, the formation top as logged from cuttings will appear to be “transitional.” (Note: not transitional in the sense that the cuttings show a varying composition, but that cuttings of a new type appear in increasing abundance as more hole is made.)Continue reading “Drilling Cuttings RECOVERY”
Crude oil tank bottoms and other petroleum oily sludges and emulsions containing paraffins and volatile hydrocarbons can be economically reprocessed with heavy-oil dehydration facilities to recover residual hydrocarbons and to achieve volume reductions.Continue reading “Oily Sludges Thermal Treatment”
A key element in the offshore drilling supply chain is the onshore supply base. The wastes most commonly associated with offshore E&P activities include: Drilling fluids, drill cuttings, produced water, treatment, workover, and completion fluids, deck drainage, produced sand, naturally occurring radioactive materials, and other assorted wastes.
Directional Boring, often undifferentiated from Horizontal Directional Drilling (HDD), is a minimal impact trenchless method of installing underground pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground bore path by using a surface-launched drilling rig. – wiki
