In this paper the application of corrosion management principles is shown to identify a clear path for managing MIC in for example crude oil transport, multiphase gathering and water injection pipeline systems. The basic steps of corrosion threat assessment, mitigation selection...

...Abstract The produced water used in water injection plants for the secondary oil recovery typically has high concentrations of chlorides, sulphates, iron and microorganisms, mainly Sulphate-Reducing Bacteria (SRB). As it is known, these kinds of bacteria produce microbiologically influenced...

...multistage-pump corrosion - erosion channeling water injection INTRODUCTION The non-destructive evaluation of surface morphology in pumps components during routine overhaul is a useful method for the assessment of the criticality of specific degradation modes1. ¹ This method...

... supported by microscopic examination of electrode surfaces after test completion. The increased general corrosion rate and pitting penetration rates that were observed during nitrate treatment were substantially reduced by the best performing inhibitors. biofilm water injection produced water sulfide...

... water injection produced water storage tanks pipelines INTRODUCTION Microbial growth in oilfield water systems can cause severe problems including energy losses due to increased fluid frictional resistances, formation plugging, souring of oil and gas and microbiologically influenced corrosion (MIC...

The Rotating...

... to select the best performing corrosion inhibitors to treat Zubair aquifer and effluent brines associated with oil production and water injection systems of West Kuwait oil fields where sour crude is produced. The wheel, Rotating Cylinder Electrode (RCE), and the autoclave tests were used to screen...

Water injection seawater formation water water treatment chemicals RCE L80 carbon steel INTRODUCTION Two years ago a major oil company in Kuwait initiated a seawater injection project in the northern oil fields of Kuwait. The purpose of this project was to maintain...

Wherever free...

..., and many tools have smaller masses. The impacts made as the tool is returned up the well are less damaging than those produced when the tool descended the well. Abstract Over the last few years, material options for downhole tubing in water injection wells, particularly subsea wells where the cost...

... in oilfield water injection and reservoir systems. In seawater systems, chlorine injection at the seawater lift pumps is the most common primary method of control ⁵ . Because, chlorine is generally lost at the deaeration stage, and biological control is therefore maintained by the use of organic...

... and 100 ml of GAnB stock cultures for enrichment. Each SBMT was run in parallel with the others. Six SBMTs were set up at the same time and treated identically. Flow was maintained continuously at 8 liters per minute, equating to 1 m/s , this being a typical velocity for water injection systems...

... water for the tests. Abstract Water soluble drag reducer chemicals have enabled significant increases in flow rates in many oilfield water injection systems. In some cases there is concern that this could leads to increased oxygen corrosion whenever the dissolved oxygen concentration strays above...

...Abstract This investigation was carried out to determine the most effective biocide inhibitor for Northern Arabian Gulf Seawater. This seawater will be used for water injection purposes for some oil fields in Kuwait. Arabian Gulf Seawater is known to be very saline during the summer months...
