Conference Paper
Reliability of equipment is indispensable for the uninterrupted operation of any oil & gas producing facility. Over a period of time, some oil wells producing sour crude were also added to the incoming feed of Gathering centres, which were originally designed for processing sweet crude. Most of the facilities were designed and installed prior to th...

Bacteria population density may provide a viable corrosion control metric for microbiologically influenced corrosion (MIC) in oilfield water handling systems. This could ensure that the population of sulfate reducing bacteria (SRB), acid producing bacteria (APB), general aerobic bacteria (GAB), and general anaerobic bacteria (GAnB) in the operating...

Kuwait is the 5th largest oil producer in the world with a current crude oil production represents about 9% of the world's oil. The country's goal is to increase the production through the Strategic Plan 2020 and the Strategic Plan 2030. The Kuwait Oil Company (KOC) is the primary national organization responsible for exploration, drilling, product...

Bacteria population density may provide a viable corrosion control metric for microbiologically influenced corrosion (MIC) in oilfield water handling systems so that the population of the different strains of bacteria such as sulfate reducing bacteria (SRB), acid producing bacteria (APB) [also classified as general aerobic bacteria (GAB)] and gener...
Article
Design Flaw Induced Corrosion (DFIC) is a new term coined by the authors to capture those corrosion failures in some exotic alloys that have occurred within a short period of service in an environment where the metallurgy of the failed component is compatible. DFIC is not new to the process industry. The purpose of coining the new term is to bring...
Article
Springs made from UNS NO7750 for pressure relief valves (PRV) that were installed in oxygen scavenger skids failed by extensive corrosion after a short time period of two years. The metallurgical compatibility between the material used for springs and the process fluid was considered adequate. A thorough investigation was performed, which included...
Conference Paper
A 41 km. (25.5 mile) long, 508 mm (20″) Fuel Gas pipeline (FG048) was in service to supply Fuel Gas to oil gathering centers (GC) in the West Kuwait area since 1968. It was required to convert the pipeline for reverse flow of HP Gas from a new gas gathering center in West Kuwait. During MFL-ILI survey prior to conversion, several undefined anomalie...
Conference Paper
This paper details the complete four-step Liquid Petroleum - Internal Corrosion Direct Assessment (LP-ICDA) for two operationally different liquid petroleum pipeline systems owned by Kuwait Oil Company. The internal corrosion pipeline wall metal losses were originally predicted using a uniform pitting factor and subsequently upgraded by a dynamic p...
Article
Proper Quality control (QC) plays a vital role during manufacturing of Oil and Gas facilities new equipment. Improper QC does occur sometimes resulting in sub-standard products, which may be silent for years till the right conditions are in place and then contributes to major failures. These non-conformances during manufacturing may lead to acceler...
Article
In the Oil/Gas production facilities, leaks in the Aboveground Storage Tank (AST) is a major threat. The majority of AST construction prior to 1980's, were over bituminous sand mix layer for levelling and to minimize the tank leakage due to the external corrosion of bottom plates. The bituminous sand mix layer partially shields the Cathodic Protect...
Article
The implementation of the 150-mv CSE polarization shift from natural potentials criterion is an appropriate methodology for addressing effective CP of aboveground storage tanks. The implementation of the methodology can also reduce the current to the optimum value, reduce system operating cost, and lead to higher anode life and less oxygen depolari...
Conference Paper
The professionals across the Oil & Gas industry have strived to combat the adverse effects of Hydrogen Sulphide and maintain the integrity of vital facilities. The detrimental effects of Hydrogen Sulphide on process equipment has remained as one of the prime subject of research in Oil & Gas Industry, fostering the advancement of inspection philosop...
Conference Paper
Hydrogen damage to pressure vessels in a Crude Oil Production facility is not uncommon. The intriguing question is about the decision to continue affected vessels in safe operation if such decision is supported by an accurate engineering assessment of the damage and the impending risk. Engineering assessments of the vessels instill confidence for s...
Conference Paper
More than half of the world’s oil and gas pipelines are classified as non-piggable. Pipeline operators are becoming aware there are increased business and legislative pressures to ensure that appropriate integrity management techniques are developed, implemented and monitored for the safe and reliable operation of their pipeline asset. The Kuwait O...
Article
Ultrasonic scanning has been implemented in the oil and gas industry as an effective tool for the detection and monitoring of service induced damage to sour service facilities. The ultrasonic technique used in the industry combines various probes to detect damage at an early stage to prevent failure of piping and process vessels. The technique has...
Article
Sacrificial Anodes based Cathodic Protection System inside a pressure vessel may prove to be grossly inadequate for certain mode of operation if the vessel internals made up of Corrosion Resistant Alloys are not well taken care of during design and / or installation. This paper discusses the causes of accelerated consumption of Aluminium Sacrificia...

Nickel Aluminum Bronze (NAB) is frequently the material of choice for the fabrication of equipment such as pumps, valves, etc. for seawater service. In general, the corrosion performance of this alloy material in seawater is very satisfactory and its resistance to cavitation is excellent. However, component failures have been occasionally encounter...

... Al-Sulaiman 3 suggested the bituminous layer shields the protection current, thus reduces the efficiency of the ICCP. 3 In addition this layer traps moisture and corrosive species between the tank bottom plates and the bituminous pad creating a corrosive environment. 3 Yu 4 on the other hand, found air gaps between the tank bottom plates and the bituminous pad to retard the CP current flow, resulting in reducing the protection of the tank bottom plates. ...
... Thermoplastic polymeric materials are often used as seals and gaskets in harsh offshore oil and gas industry applications where sour gas attack is a problem [1,2]. The degradation of plastics in a marine environment has focussed on the effects of biodegradation, however in many applications it is the exposure to chemicals found in extraction gases and liquids which present the greatest threat to the performance of the plastic components [3,4]. In down well situations, contact with gases such as hydrogen sulfide (H 2 S), carbon dioxide (CO 2 ) and methane (CH 4 ), and fluids at high pressure and temperature (up to 200 C, 10 8 Pa) present the most taxing of environments. ...
... Pipeline integrity may be severely impacted by the gradual decrease in production flow rate over time which can amplify internal corrosion issues [12][13][14]. Oxidation, bacterial activity, and localised corrosion, including those cause by deposits, are all factors for concern of pipeline integrity. ...
... Once defined by a major company, KPI values often replicate across the industry and are used to assess the efficacy of mitigation programs (El-Sherik, 2017). Typical empirical KPIs used by field operators in the Oil and Gas sector can range between 1 and 10,000 bacteria per milliliter or cm 2 , being in most cases 100 bacteria per ml or cm 2 the maximum tolerable concentration for cultivable sulfate reducers (Al-Shamari et al., 2013). Yet, ideally, the definition of microbial KPIs should be made in a case-by-case basis, taking into account trends of the microbiological, physicochemical and operational context, rather than adopting a generic figure (NACE-International, 2018). ...
... Al-Sulaiman et al. (Al-Sulaiman et al., 2010) found indications of severe internal corrosion on a light crude oil (LCO) pipeline from API 5L-Grade B interconnecting a wet tank to a common header with corrosion depth of more than half of pipeline wall thickness. In spite of its 30-year design life, the pipeline was corroded within 7 years of operation. ...
