Shell staff won the highly regarded 1st Place Technical Paper Award at the annual international and exhibition conference of the Society of Petroleum Engineers (SPE), which ended in Lagos last week.
Well engineers – Augustine Okosun, Osehojie Ojeh-Oziegbe, Oluwatobilola Aribike, and Oladokun Adubi were commended “for an outstanding display of in-depth technical knowledge and quality delivery” in their presentation.
The paper titled, Application of Perforate, Wash, and Cement (PWC) Technology for Annular Remediation in Deepwater Well Abandonment, deals with the PWC technology.
This is used for annular (the space between casing and wellbore) remediation to install permanent isolation barrier during well abandonment for zonal isolation and prevent fluid migration.
This process is crucial in achieving safe and permanent abandonment of a well, preventing potential well integrity issues and environmental hazards.
The PWC technology which has been established globally as an efficient and cost-effective solution for annular remediationwas deployed for the first time in deepwater Nigeria during the Bonga field Midlife plug and abandonment campaign in Q2 last year.
The paper highlights the significant savings in cost and time compared to conventional methods.
The SPE Award for Best Technical paper underscores the kind of cutting-edge technology which SNEPCo has deployed to achieve top quartile performance and operation excellence in the Bonga field.
On behalf of his colleagues, Mr. Okosun said: “Technology is a key aspect of the culture of excellence in our operations, and we hope the insights we shared will encourage a culture of cost effective and environmentally sound operations which the operators need to remain competitive.”
This process is crucial in achieving safe and permanent abandonment of a well, preventing potential well integrity issues and environmental hazards.
