Frequently, these challenging conditions faced are tested individually with pressurized mass loss coupon testing at bottom...

... and performance issues seen in this geothermal field have recently been developed. This paper will highlight the corrosion performance of these new alloys, along with their more cost effective manufacturing processes.

...⁺, and SO₄^2–. Sea spray evaporates to form more and more concentrated solutions, eventually converting to dry salts. These salts, upon deliquescence, follow the evaporation pathway in reverse, initially forming highly concentrated chloride-rich brines, and progressively become more and more dilute...

...Abstract Injection water/brine handling systems are important elements of the oil & gas field operations. Considering carbon steel as default material of construction for water/brine handling pipelines, a rapid determination of steels’ corrosion is the key-element of the oil & gas field’s...

... UNS S31803⁽¹⁾ (1.4462) and superduplex steel UNS S32760 (1.4501) was tested with welded round tensile bars under constant load of 90% AYS (measured at the test temperature) fully submerged in brines with 10 to 45 g/L chloride in the presence of 150 mg/L bicarbonate under partial pressures...

... is widely used as a construction material in oil and gas facilities, at temperatures between 20 and 60°C by performing corrosion tests in CO₂ saturated brines (NaCl). ^{16 - 20} These studies found pits as evidence of localized corrosion and underlined the effect of the presence...

...Abstract Metallic components and equipment for service in the marine, power generation and process industries are commonly exposed to halide-bearing waters and brines. These media, especially when hot, can be very aggressive. While highly alloyed NiCrMo products generally provide resistance...

...Abstract An extensive metal compatibility study has been undertaken in order to qualify the high density cesium acetate brine for duty as a well construction fluid for use under ultra/extreme High Pressure High Temperature (HPHT) conditions. As a first step to qualify this new brine system, tests...

... chloride containing applications. The same has been true for titanium in geothermal brine applications. The US Bureau of Mines first reported on the excellent corrosion performance of titanium more than 30 years ago. The Salton Sea KGRA has utilized titanium since the early 1990’s to control the excessive...

...The risk for corrosion in brines is mainly associated with the chloride content, temperature, pH and oxygen level, and of course the alloying content of the stainless steel. This paper aims to explore the corrosion resistance of some stainless steels in highly concentrated chloride solutions...

...Abstract Round tensile bars of the stainless steel UNS S 31635 (AISI 316Ti; DIN 1.4571) with a hardness of HRC 23 were subjected (in triplicate for each set of conditions) at room temperature for 720 h under 70% and 90% of the actual yield strength (AYS) fully submerged in brine with 1 g/L and 30...

... in oxygen-free brine (partly in the presence of oil-based inhibited sulfur solvent) at 50 and 100°C under highly sour conditions. None of the test specimens suffered from any visual corrosion attack. Corrosion rates calculated from surface related mass losses were in all cases far below 0.1 mm/y...

...ABS is injected into the wellbore production annulus to scavenge any dissolved oxygen in the brine used in the well completion process. In these applications successful treatment means reducing the oxygen level to very low levels. Experience has shown that brine that contains less than 10 ppb...

...Abstract The high-density clear brine, such as CaCl₂ has been widely applied in the oil and gas exploration field as completion or packer fluid, however, some failure cases of duplex stainless steels or super martensitic stainless steels in high density CaCl₂ brine have been...

...Abstract The corrosion of carbon steel materials in brine solutions challenges industry to weigh the economics of lower cost materials of construction against the mechanical integrity and service life of equipment. The data and comparisons contained here will consider this challenge from...

... desirable due to chemical and produced fluid (oil, brine) compatibility concerns. The preflush stage also reduces the tubing and near wellbore temperature, which reduces the scale inhibitor adsorption rate and reduces the risk of premature precipitation of a treatment designed to phase separate at elevated...
