... Abstract The drive towards net zero by 2050 has instigated the development of alternative energy sources to fossil fuels which has resulted in a big focus on geothermal energy projects. Geothermal brines typically contain dissolved minerals and gases that can cause scale deposition in wells...

... Cleaning operations of ESPs affect the production and may damage the ESP, a preventive solution for the mitigation of calcium carbonate is therefore preferred. The fouling mitigation strategy is to develop a product able to prevent both the calcium carbonate scale and asphaltene depositions...

... been in production since 1996. In early field life, the initial scaling assessment predicted barite scale deposition in the tubing, prompting the adoption of preventive inhibition measures. Scale dissolver treatments and inhibitors were dutifully employed throughout most the field's life, but some...

... of issues related to mineral scale deposition can be encountered that impact the efficiency of CO 2 injection and utilisation/storage. These can include calcium carbonate deposition during CO 2 capture in a calcium looping process, halite (NaCl) precipitation during supercritical dry CO 2 injection...

... Calcite scale formation is a common issue in oilfield production from carbonate reservoirs. It causes losses in production and additional costs for prevention or even remediation of the deposits in the pipe walls and valves. Although the thermodynamics of the equilibrium and the use of scale...

... ) − ] The efficacy of this type of treatment, or in other words, how long the well will be protected against scale deposition, depends on the level of retention of the SI in the rock formation, which depends on the interaction of the SI and the rock minerals of the rock formation. It is generally accepted...

..., such as producing wells, surface facilities, reservoir formation and re-injection lines. Scale inhibitors have been commonly used in the oil and gas industry to prevent the mineral deposition. The objective of this paper is to optimize a scale treatment strategy in a geothermal doublet injector-producer layout...

... is the underperformance of the water flood system, which led to a severe oil production decline, 30% below target by the end of 2022. The water injector wells suffer from significant scale deposition over time caused by water incompatibilities and pressure/temperature changes. Even though measures such as applying...

... with calcium carbonate, barium sulfate, calcium sulfate and organic compounds suggest that the technology of magnetic treatment of fluids can be applicable in the prevention of scale and/or organic deposits in oil producing fields. Colic and Morse (1999) suggested that the effects caused...

... In the in-situ flow cell, both surface deposition and bulk precipitation were measured simultaneously under flow conditions. An open system, which was designed by colleagues at the University of Leeds, was used as this technique gives a more realistic simulation of oilfield conditions. The cell...

This paper summarises an experimental programme to examine the proposed mechanism of operation of the EMD under controlled laboratory conditions. Flow experiments were performed under...

... assembled in production sites subjected to water flooding might suffer from scale deposits of barium sulphate. Scaling may result in production stops, production restriction and also heavy workover jobs, reducing project profitability. The simulation of the scaling formation process allows the observation...

... Abstract Barium sulfate is one of the most serious problem in mineral scale precipitation, the deposition of barite on the surface is a concern to flow assurance in the oil well. The scale formation is typically predicted by thermodynamic solubility limit. However, it is believed...

Ba 2+ concentrations in effluents were measured and compared with the bottle test results to investigate the performance of PPCA in porous media. Results show that PPCA cannot stop scale deposition in porous media at the MIC...
