Non-aqueous drilling fluids may be removed from a wellbore or tubing nor casing within the wellbore by introducing into the well a biodegradable aqueous fluid comprising banana.

Method of removing non-aqueous drilling mud with banana containing fluid

A cement slurry may be separated from a drilling mud in a wellbore by introducing into the wellbore an aqueous fluid having a weighting agent, a hydratable gellant powder having a particle size distribution from about 150 to about 300 mesh; and a suspension agent of particulates of a resin encapsulated hydratable polymeric viscosifying agent, the suspension agent having a particle size distribution such that at least 90% of the particulates are retained on a 20 mesh screen and 100% of the particulates are retained on a 6 mesh screen. The weighting agent may be suspended in the viscous fluid by hydrating the hydratable gellant powder. At higher temperatures and after degradation of the hydrated gellant, the weighting agent remains suspended by degrading the resin of the suspension agent and releasing the hydratable polymeric viscosifying agent into the wellbore.

Method of using resin coated sized particulates as spacer fluid

A downhole system () includes a tubular () having a longitudinal axis (), and a trace () applied on the tubular (). The trace () includes a conductive portion () formed from an electrically conductive material () and the trace () is configured to deliver a signal between uphole and downhole locations of the tubular ().
