Abstract

A method of using a suppression factor fluid during a well activity is provided. The method comprising the steps of introducing a suppression factor fluid into a wellbore, the suppression factor fluid comprising an untreated monovalent brine; and a suppression sugar alcohol, the suppression sugar alcohol in an amount operable to achieve a suppression factor, wherein a density upper limitation of the suppression factor fluid is greater than the density upper limitation of the monovalent brine; and completing the well activity in the wellbore, such that the suppression sugar alcohol inhibits crystallization during the well activity.

Claims (15)

1. A composition for use as a suppression factor fluid, the composition comprising:

50% by weight to 90% by weight of a monovalent brine;

10% by weight on a dry weight basis to 50% by weight on a dry weight basis of a suppression sugar alcohol, wherein the suppression sugar alcohol is selected from the group consisting of sorbitol, xylitol, and combinations thereof; and

a stabilization compound, wherein the stabilization compound is operable to inhibit degradation of the suppression sugar alcohol, wherein the stabilization compound comprises an amine base, wherein the amine base is selected from the group consisting of monoethanolamine (ME A), diethanolamine (DEA), triethanolamine (TEA), ethylenediamine (EDA), diethylenetriamine (DETA), triethylenetetramine (TETA), tetraethylenepentamine (TEPA), pentaethylenetetramine (PETA), pentaethylenehexamine (PEHA), aminoethylpiperazine (AEP), ethyleneamine E-100 (available from Huntsman Corporation), piperazine, diethylhydroxylamine (DEHA), diethylaminoethanol (DEAE), dimethylethanolamine (DMEA), methoxypropylamine (MOPA), morpholine, naminopropylmorpholine (APM), 4-[2-hydroxyethyl] morpholine, diglycolamine, N-[3-aminopropyl] diethanolamine, aminoethylethanolamine (AEEA), and combinations thereof,

wherein the suppression factor fluid is operable for use as a well fluid,

wherein the suppression factor fluid inhibits crystallization during a well activity.

2. The composition of claim 1 , wherein the monovalent brine is selected from the group consisting of a sodium bromide brine, a sodium chloride brine, a sodium formate brine, a potassium bromide brine, a potassium chloride brine, a potassium formate brine, a lithium bromide brine, a lithium chloride brine, cesium formate brine and combinations thereof.

3. A method of creating a suppression factor fluid, the method comprising the steps of:

adding an amount of between 10% by weight on a dry weight basis and 50% by weight on a dry weight basis of a suppression sugar alcohol to an untreated monovalent brine to create a mixture, wherein the amount of a suppression sugar alcohol is operable to achieve a suppression factor of between 0.1 and 10, wherein the mixture comprises between 50% by weight and 90% by weight of the untreated monovalent brine, wherein the suppression sugar alcohol is selected from the group consisting of sorbitol, xylitol, and combinations thereof;

mixing the mixture until the suppression sugar alcohol is dissolved; and

adding an amount of a stabilization compound, wherein the stabilization compound is operable to inhibit degradation of the suppression sugar alcohol, wherein the stabilization compound comprises an amine base,

wherein the suppression factor fluid is operable for use as a well fluid, wherein the suppression factor fluid inhibits crystallization during a well activity.

4. The method of claim 3 , wherein the amount of the suppression sugar alcohol is added in a solid form.

5. The method of claim 3 , wherein the amount of the suppression sugar alcohol is added in an aqueous form.

6. The method of claim 3 , further comprising the step of adding additional monovalent salt to the suppression factor fluid after the suppression sugar alcohol after the step of mixing the mixture, such that the additional monovalent salt achieves an operational density of the suppression factor fluid.
