... types must be carefully considered during both planning and execution stages. In practice, we encounter reservoirs with variable permeabilities, different lithologies, and mud systems that are not always adequate. Lessons gathered from various environment types and innovative methods of acquiring data...

... and qualitative data concerning fluid coloration. Experiments were performed to catalog the optical fluid density characteristics of typical hydrocalbons, formation waters, filtrates, drilling mud systems, and mixtures of these fluids. Utilizing this data base, optical density measurements can do an excellent...

... Abstract This paper presents laboratory data and field application results on a new water based mud system which utilizes Potassium Carbonate, a special polymer formulation and a polyglycol. The surfactant properties of the polyglycol around it's cloud point, the existence of normal force...

... ABSTRACT This paper discusses the drilling related complexities of the Greater Ekofisk basin which have demanded innovative shale stabilizing mud systems. The innovative mud systems discussed include "pseudo and synthetic" oil emulsion fluids; and cationic water based fluids. Phillips Petroleum...

.... Onshore disposal of the used mud system is the primary concern. Regulations regarding heavy metals, oil, and salt content in muds can restrict the method(s) of disposal. Because of these restrictions, most drilling operators are now requiring up front analysis of mud systems. This issue has become...
