02030 TETRAKISHYDROXYMETHYLPHOSPHONIUM SULFATE (THPS) FOR DISSOLVING IRON SULFIDES DOWNHOLE AND TOPSIDE - A STUDY OF THE CHEMISTRY INFLUENCING DISSOLUTION

Product Number: 51300-02030-SG

ISBN: 02030 2002 CP

Author: Paul D Gilbert, Jason M Grech, Robert E Talbot, Malcolm A Veale, and Kansas A Hernandez

Publication Date: 2002

Recently, it has become apparent that THPS, often used as a biocide in oilfield operations, also dissolves iron sulfide scales. The chemistry of this process is reviewed and a study of iron sulfide dissolution, over a range of conditions, is reported.

A Further Look At The Impacts Of Corrosion Inhibitor On Scale Prevention

Scale and corrosion inhibitors are commonly used in many oil and gas production systems to prevent inorganic deposition and to protect asset integrity. Scale inhibitor products are based on organic compounds with phosphate or carboxylic functional groups such as amino phosphonates, phosphate esters, phosphino polymers, polycarboxylate and polysulfonates,1 as shown in Figure 1. These anionic groups have strong affinity to alkaline earth cations and can adsorb on the active growth sites of scale crystal (Figure 2), resulting in stopping or delaying the scale formation process.

Metal sulfide mineral scaling, fouling and deposition are frequently encountered problems in geothermal systems. Their formation, crystallization and deposition occur principally because of their extremely low solubility, based on the low solubility product (Ksp). Among the metal sulfides that cause problematic issues, the most common ones are iron sulfide (FeS), zinc sulfide (ZnS), lead sulfide (PbS), and, less frequently, antimony sulfide(s) (Sb2S3 and Sb2S5). Zinc sulfide, for example, has a Ksp of 2·10-25 mol²/L², whereas for PbS, it is 1·10-28 mol²/L² (~ three orders of magnitude less soluble). ZnS can precipitate either as Sphalerite or Zinc Blende, and PbS commonly crystallizes as Galena. Mitigation of such ZnS and PbS precipitates and deposits can be achieved by chemical interventions, by the addition of organic chemical additives to the water. Herein, we report the inhibitory effects of phosphonate-based chemical additives for ZnS and PbS scales. These additives can inhibit formation of sulfide scale, and, significantly, prevent its deposition on metal surfaces. The efficiency of these additives is dosage-dependent, and relatively high inhibitor concentrations are needed for their inhibitory activity to take place. Possible mechanisms will be discussed focusing on inhibition and dispersion.

Mitigation Of Scaling Potential Using Organophosphorus Phosphonates In High-Temperature And High-Hardness Carbonate Formations

Product Number: 51322-17588-SG

Scale is an adherent deposit of inorganic compounds precipitated from water onto surfaces. Most oilfield waters contain certain amounts of dissolved calcium, barium or strontium salts. The mineral scale can be formed by chemical reactions in the formation water itself, by mixing of formation water with injected seawater, or by mixing of the well streams of two incompatible oilfield waters. In carbonate reservoirs, when calcium is deposited as calcium sulfate or calcium carbonate scale, a loss of production and increased maintenance expenses can result. Therefore, effective mitigation of scaling potential is of importance to the oil producers.

Nanotechnology-Based Detection Method for Speciation and Differentiation of Phosphonate Scale Inhibitors

The accurate and precise analysis of scale inhibitors plays an important role in making key decisions on the efficiency of scale squeeze and continuous-chemical injection treatments. At present, several techniques exist for scale inhibitor analysis, but each method has its own limitations and tedious analysis process. In addition, these methods often give results of either total chemical content or elemental analysis without details of chemical speciation. Especially for phosphonate scale inhibitors, it is well known that there is no analytical methods available on the market to differentiate different species of phosphonate inhibitors, which impedes the applications of different types of phosphonate inhibitors on the scale treatment. There was therefore a need for a next-generation method for phosphonate analysis. An experimental methodology has been developed based upon the use of gold nanoparticles to enhance chemical signatures of scale inhibitors in brines using Surface Enhanced Raman Spectroscopy (SERS). This methodology enables speciation and measurement at low concentrations in the range of 1 to 100 mg/L (ppm). This study used two different phosphonate-type scale inhibitors, and initial laboratory results prove that this novel technology can help to differentiate between two different phosphonate-based chemicals.
