Abstract

Petrolü su veya polimer katılmış su ile oteleme genellikle ağir petrol sahalari için etkin olmayan bir yöntem olarak kabul edilir ve onların yerine daha cazip görünen kimyasal ya da ısıl gelişmiş petrol kazanımı yöntemleri tercih edilir. Halbuki ağır petrolun su yada polimer ile otelenmesi esnasında öne çıkan özgün bazı mekanizmalar bulunmaktadır. Bu özgün mekanızmalar dolayısı ile 10,000 cp yada daha yüksek viskositedeki ağır petrolün başarılı bir şekilde su ya da polimer ile ötelenmesi mümkündür. Bu çalismada ağır petrolün su yada polimer ile ötelenmesi esnasinda etkin olan özgün mekanizmalar ayrıntılı olarak incelenmiş ve başarılı bir uygulama için gerekli adımlar açıklanmıştır. Ulaşılan sonuçlar Kanada’nın ağır petrol sahalarındaki başarılı su, polimer ve su+polimer ile öteleme uygulamalarının sonuçlarıyla temellendirilmiştir. Umulur ki bu başarılı deneyimleri dünyanın ve Türkiye’nin ağır petrol sahalarına da aktarabiliriz.

Waterflooding of Heavy Oil Reservoirs

Abstract

Waterflooding or polymer flooding is sometimes dismissed as an ineffective process for heavy oil fields, with development plans focused on more exotic and expensive recovery mechanisms such as chemical or thermal processes. There are a number of unique mechanisms that operate in heavy oil fields under water and polymer flood. It is, therefore, possible to succesfully flood heavy oil reservoirs with viscosities up to and beyond 10,000 cp oil viscosity. This work elaborates on the unique mechanisms operating in heavy oil water and polymer floods, presents a workflow for successfull implementation and supports its conclusions with a number of case studies, namely, actual successful field examples from Canadian heavy oil fields. The hope is that, this experience can be translated to heavy oil fields in other parts of the world including Turkey.
