Corrosion behavior of ultra-high strength drilling steel in alkaline brines containing hydrogen sulfide at high temperature
(Nace International, 2016)
In-situ electrochemical measurements were used to study the sour corrosion of ultra-high strength low alloy carbon steel (UHSLA) in alkaline brines at 200 °C. The solutions were buffered with NaHCO3 / Na2CO3 / NaOH to pH ...
Effects of CO2 and H2S on corrosion of martensitic steels in NaCl(aq) at low temperature
(Nace International, 2016)
Corrosion studies were conducted for martensitic carbon steels in brine solutions at 4 °C and 10 MPa (1450 psi), which simulated the subsurface environments encountered in Arctic drilling. Three environments with a 5 % wt. ...
Corrosion behavior of 13Cr casing steel in cement-synthetic pore solution exposed to high pressure CO2 and H2S
(The Electrochemical Society, 2015)
As deeper wells drilled for oil and gas extraction encounter higher pressures, temperatures, and concentrations in the downhole environment, it becomes increasingly important to consider the integrity of the casing that ...
Effect of H2S and CO2 on Cement/Casing alloy interface corrosion integrity for cold climate oil and gas well applications
(The Electrochemical Society, 2016)
A study has been carried out to investigate sweet and sour corrosion at the cement-casing interface for offshore oil and gaswells in cold climate. The test solution chemistry was determined by sampling pore water from ...
Asymptotically ... equivalence of double sequences of sets defined by modulus functions
(2019)
Fast (1951) and Schoenberg (1959), independently, introduced the concept of statistical convergence and many authors studied this concept. Mursaleen and Edely (2003) extended this concept to the double sequences. The idea ...
Asymptotically lacunary I-invariant equivalence of sequences defined by A modulus function
(2018)
In this paper, we introduce the concepts of strongly asymptotically lacunary ideal in-
variant equivalence, f-asymptotically lacunary ideal invariant equivalence, strongly f-asymptotically
lacunary ideal invariant ...
Asymptotically ... equivalence of double sequences defined by modulus functions
(2019)
Throughout the paper N denotes the set of all positive integers and R the set of all real numbers. The concept of convergence of a sequence of real numbers has been extended to statistical convergence independently by Fast ...
On some properties of rough convergence in 2-normed spaces
(2019)
The concepts of convergence on 2-normed space and rough convergence in normed spaces are important in summability theory. The concept of 2-normed spaces was initially introduced by Gähler in the 1960's. Since then, this ...
Lacunary statistical convergence of double sequences in fuzzy n-nspacesormed
(2018)
The concept of convergence of real sequences has been extended to statistical convergence and later this concept was extended to the double sequences by Mursaleen and Edely. The concept of ordinary convergence of a sequence ...
Asymptotically I-Invariant statistical equivalence of sequences of set defined by a modulus function
(2018)
In this paper, we introduce the concepts of strongly asymptotically I-invariant equivalence, f-asymptotically I-invariant equivalence, strongly f-asymptotically I-invariant equivalence and asymptotically I-invariant ...
