..., ion chromatography was used to determine the concentration of sulfate ions present in the solution. Herein, the inhibition efficiency of various phosphonic-acid based inhibitors: ATMP, PAPEMP, and BHMTMP were examined and compared against a baseline blank test. Afterward, the mechanism of inhibition...

... is intended to group wells with similar reactivities, which could require the same management actions. Taking as a starting point some formation water composition analyses, mostly sampled from injectors, our first step is to spatially interpolate the concentrations of each of the ions, resulting in maps...

... relay on the matrix interference due to contaminants and the usual high salinity in samples. In fact, SPE allowed the removal of these interferents and, also, made feasible the analyte pre-concentration. The reagent Hyamine 1622 was employed due to its ability to effectively precipitate anionic...

... to an advection-diffusion equation for a scalar field that measures the concentration of the more viscous fluid. Our results predict very high displacement efficiencies, close to 100%. Although the fluids used in industrial cementing processes are non-Newtonian, the high displacement efficiencies found...

... with other additives to tighten the fluid loss at significantly lower concentration levels, than would have otherwise been required with traditional asphaltic powders, without negatively influencing the rheological properties of the mud. Another benefit is, No screened out from the mud on shaker screens...

... of the tests must closely represent the field. This includes the brine chemistry of the well, the CO 2 concentration and pH of the fluids. This paper will detail the results of a new modelling and laboratory study which shows an extremely severe scaling regime that could be expected under the pre-assigned...

Raman spectroscopy is a well-established method that has several applications in the topside Oil & Gas industry, such as online monitoring of blending processes, amine gas treating, hydrocarbon groups, sulphates content in water flood injection system...

... system. Additionally, this system is equipped with sensors and customization capabilities to assess CO 2 concentrations in various locations, measure heat generated by the reaction between amine and CO 2 and perform sensitivity analysis with respect to the orientation of mixers and residence time...

... Abstract This article presents the results obtained in the evaluation of the joint action of the chemical inhibition (inhibitor) and the magnetic field, aiming to evaluate the possibility of reducing the minimal inhibitory concentration (MIC), seeking an increase in production in oil extraction...

.... As the emulsion presented high ionic concentration (due to a specific well), it was verified higher concentration throughout the plant. At the latter separation stages, ionic concentration (e.g., calcium) was 30% higher than the blend would suggest. To understand the condition observed at the separation vessels...

However, there still is no consensus on the best ion concentrations, which may be due to experimental designs being linear whilst EOR processes are covariantly synergistic. This work optimized the pre-salt oil recovery factor in limestone by injecting smart water...
