... added labeled as Sample C, and D, respectively. Determination of sample rheological properties Experimental setup Four beakers were used for the experiment. Each of the beakers contained 350ml of distilled water along with varying quantities of the contaminants which were added to test...

... to oil extracted from a particular oilfield ( Duncombe, 2019 ). Developing a chemical database with a comprehensive contaminants profile in the petrochemical industry with the combination of conventional and new analytical tools is essential for the management of chemical spills and associated issues...

... of biodegradation of hydrocarbon is numerous, including: waste water treatment contaminated by crude oil, and for microbial enhanced oil recovery (MEOR). Despite the latter (MEOR) being in use over a century now, it is yet to be widely accepted as an optimum large scale enhanced oil recovery technique in the oil...

It has been confirmed that the reagent has the ability to destroy sludge molecules in soil, effectively clean and restore the soil with added fertility. remediation contaminant water positive hpass upstream oil & gas spillage molecule sludge soil...

... immersed in the aquatic environments. These sensors monitor the chemicals and the PH values of the coastal areas and send alerts in real time to the monitoring centers whenever the threshold for any of the monitored contaminants are exceeded. The system is designed to utilize the available communication...

... result in large volume of the drilling fluid lost into the formation and consequently reduce the effectiveness of the drilling operations. The total successfulness of sodium silicate/cement squeeze depends strongly on whether the cement placed in the desired place without any contamination. Contamination...

... Contamination of drilling fluid by cement is an undesirable condition whereby the drilling fluid is made unfit for use due to impairment of its properties by cement particles and chemicals. Cement can enter the fluid systems from poor cementing jobs or squeeze cementing whereby calcium hydroxides...

... of contaminants. This means, chemical treatment can be employed to produce useful by-products and residual effluents that are environmentally acceptable. There are several Chemical treatments including chemical oxidation. □ Biological Treatment: Biodegradation generally refers to the breakdown of organic...

..., it is imperative to promote and propagate the use of environmentally friendly mud for drilling operation. This study investigates the drilling cutting carrying capacity of both jatropha and diesel based drilling muds. It also examines the effect of contaminants on the rheological properties of the muds...

... ABSTRACT Drilling of oil well is a capital intensive project; hence, the importance of selection of proper mud system that is free from contamination cannot be overemphasized. A poor design and contaminated drilling fluid can be very costly in the life of any well. Therefore, during drilling...

... Abstract With continuous efforts to introduce new technologies for wellbore cleaning, a near neutral pH pickling fluid has been evaluated for use as a pickling fluid. Pickle treatments are done to improve well productivity by removing various contaminants from well tubulars in an efficient...
