“…In recent years, the fast drilling fluids technology have been researched extensively and the adding ROP growth agent into drilling fluids is able to enhance ROP. In other words, ROP enhancement is able to be obtained by transforming the lubrication of metal surfaces, reducing the torque as well as preventing bit balling (Growcock et al, 1994;Bland et al, 2002;Klein et al, 2003;Dye et al, 2005). The documents indicate that water solution will impact on the nature of rock surface to a certain degree.…”

The authors attempt to investigate the interaction between inorganic components of drilling fluids and sandstones as well as the influence on the rate of penetration (ROP) imposed by inorganic components. With the analysis of Zeta potential of cuttings solution, the mechanism of the experiment is initially achieved. The results show that the ROP will be enhanced by 33.7% when AlCl 3 concentration is up to 0.01 mol/L, and therefore AlCl 3 and Al 2 (SO 4 ) 3 possess a tendency to enhance ROP. In addition, Al 3C enables Zeta potential of the solution containing cuttings shifted from negative value to zero, and finally to positive value by means of analyzing Zeta potential, which contributes to the significant improvement of ROP when Zeta potential is greater than 10 mV. Higher surface free energy created by the close-to-zero Zeta potential is conducive to crushing rocks, which in turn increases the ROP and meanwhile reduces drilling costs.

“…Unfortunately, as far as we are aware, the FR WBM system has remained rarely referenced. One similar concept is reported in the development of high-performance AFs (Al-Ansari et al 2005;Dye et al 2005;Morton et al 2005). Consequently, it is interesting to understand how FR WBM functions at a wide range of temperatures.…”

The aqueous drilling fluid (AF) with unique flat rheology (FR), as a potential alternative to nonaqueous fluids (NAFs), is meaningful in deepwater operations. In this work, a novel FR water-based mud (WBM) was presented. An evaluation of FR profiles was conducted on the designed system by detecting the typical rheological data at a certain temperature and pressure range. The results showed that for the newly developed WBM, in addition to typical FR parameters [i.e., 6-and 3-rev/min readings and yield points (YPs)], the viscosity term also delivers near-constant variations in the temperature range of 39 to 150 F. To attain FR profiles, the rheological modifier appears to be necessary for its temperatureactivated behavior. In addition, the FR WBM displays lower pressure and temperature dependence. The laboratory contamination tests indicated that the WBM system possesses excellent inhibition and lubricity properties as well as a strong tolerance to the contamination of seawater and sand/mudstone cuttings.

In industrial practice, rock hydration inhibitors, classified as amine compounds, are being increasingly used in drilling mud compositions. There is no methodology for determining this type of compounds content in the drilling mud, and proper servicing of this type of muds requires constant monitoring of their content to ensure appropriate inhibitory properties. During drilling, amine compounds adsorb on the surface of rocks and their concentration decreases during drilling and reduces the inhibitory properties of the mud. A common additive used in the composition of drilling muds is latex, the determination of which is necessary to ensure the mud parameters stability. Compounds of this type ensure the stability of the borehole wall, while their content also decreases during drilling. The results obtained from the research presented in the article allowed to propose methods for the determination of amine compounds and latexes. These methods can be used in the field laboratory when servicing drilling muds. The article presents the methodology for determining the content of new types of chemicals used in drilling muds, i.e. rock hydration inhibitors classified as amine compounds and latexes. The proposed methods enable proper servicing of muds with the addition of the agents that ensure the maintenance of appropriate mud properties. The method for the determination of amine compounds consists in determining the total nitrogen in the drilling mud filtrate. Dilution of the filtrate provides the results within the measuring range of the method and reduces the concentration of chloride ions, the amount of which may not exceed 10 000 mg/dm3. The first method of latex determination is weight determination of the dry residue after separation of the latex from the filtrate with acetone. The second one is based on nephelometric measurements of a tenfold diluted filtrate. The measurement result is the NTU (nephelometric turbidity unit) value depending on the latex content in the filtrate. All of the developed methods require the preparation of calibration curves, which are the basis for calculating the content of a given agent in the mud.
