Drilling through salt Risks associated with drilling through salt

Source: Franz Kockel et al. (1996) Geotektonischer Atlas von NVV Deutschland Bundesanstalt für Geowissenschalten und Rohstoffe, Hannover. In recent years, an increasing number of oil and gas projects involving drilling through salt have been presented by different exploration companies. It is important for underwriters, lawyers, regulators, financiers and engineers to have a clear understanding...

The great potential of nanomaterials in drilling & drilling fluid applications

The continuous development of global economy with decreasing in available hydrocarbon sources and increasing discovery and extraction costs due to decrease in-situ oil and gas reservoir, displays the necessity of using new techniques for the improve rate of penetration and productivity in well. Nanotechnology has already contributed significantly to technological advances in the energy industri...

Deep drilling moves ahead

Deep-water drilling in the Gulf of Mexico could resume within weeks under a policy by the US government, which has come under increasing criticism from the oil industry and politicians in the region over the impact of the drilling halt and worries from scientists that the full impact has not yet been assessed. Oil and gas exploration in the gulf’s deep waters has been stopped since May, when Ob...

Drilling Waste Treatment

Contamination types, levels and their behavior within drilling wastes is determined by the local geological conditions and drilling mud design; notably lubrication fluids, weighting agents and anti-foaming agents. Such additives can contain potentially toxic elements such as aluminum and barium. Besides being contaminated, drilling wastes often have a high pH due to the addition of lime, causti...
