A composition for use in a wellbore activity, the composition comprising an iodide brine, the iodide brine operable to be used in the wellbore activity, the iodide brine comprising an iodide salt, an aqueous fluid, and an iodide protectant, the iodide protectant operable to prevent the presence of free iodine in the iodide brine, where the iodide protectant is present in the range between 0.001 v/v % and 5 v/v % of the iodide brine.

Stabilization of iodide-containing brines and brine mixtures

A composition for use in a wellbore activity, the composition comprising a stabilized divalent iodide brine, the stabilized divalent iodide brine comprises a divalent salt system, where the divalent salt system comprises a divalent iodide, an primary iodide stabilizer, the primary iodide stabilizer operable to remove free iodine, prevent the formation of free iodine, and suppress TCT, and an aqueous fluid, where the stabilized divalent iodide brine has a density greater than 11 lb/gal, where the stabilized divalent iodide brines has a TCT of less than or equal to 70 deg F.

Stabilization and reduction of TCT of divalent iodide-containing brines

A composition for use in a wellbore activity, the composition comprising a stabilized monovalent iodide brine, the stabilized monovalent iodide brine comprises a monovalent salt system, the monovalent salt system comprises a monovalent iodide; a primary iodide stabilizer, the primary iodide stabilizer operable to remove free iodine, prevent the formation of free iodine, and suppress TCT; and an aqueous fluid, where the stabilized monovalent iodide brine has a density greater than 10 lb/gal, where the stabilized monovalent iodide brine has a TCT of less than or equal to 70 deg F.

Methods for monitoring a drilling process that uses a drilling fluid are described. The methods include measuring an initial salinity of a water phase of the drilling fluid, diluting the drilling fluid with a known amount of water to form a diluted drilling fluid, measuring a salinity of a water phase of the diluted drilling fluid, determining an initial relationship between a salt content and a water content in the drilling fluid using the initial salinity of the water phase of the drilling fluid, calculating an initial water content of the drilling fluid using the measured salinity of the diluted drilling fluid and the initial relationship between the salt content and the water content in the drilling fluid, and adjusting one or more drilling parameters in response to the calculated initial water content.

Methods for determining the water content of a drilling fluid using water phase salinity

Methods and apparatuses that measure thermal conductivity and electrical conductivity of a emulsified drilling fluid may be used to indirectly measure the salinity and the average specific gravity of the solids in the emulsified drilling fluid. For example, a drilling assembly may comprise a drill string extending into a wellbore penetrating a subterranean formation; a pump configured to circulate a drilling fluid through the drilling assembly; a first flow line fluidly coupling the wellbore to a retention pit; a second flow line fluidly coupling the retention pit to the pump; a third flow line fluidly coupling the pump to the drill string; and an in-line analysis system fluidly coupled to the retention pit, fluidly coupled to the second flow line, or fluidly coupled to the third flow line, the in-line analysis system comprising a thermal conductivity meter and/or an electrical conductivity meter to a sample container.
