Inorganic Nutrients in Swedish River
ISBN: 9783659634482 / Angielski / Miękka / 2014 / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Rivers have been playing most important role as fresh water source and medium of nutrient transportation from terrestrial to aquatic ecosystem. Inorganic nutrients (DSi, DIN and DIP) are plant available mostly control the productivity of aquatic ecosystem.Study of dissolved inorganic nutrients concentrations in 12 Swedish rivers of different basin characteristics demonstrated both similar and varying behaviour from river to river and from season to season depending on catchment hydrology; land use and geology. Highest concentration did not coincide with the highest runoff. High DSi...

Planung von UBD in horizontalen Bohrlöchern zur Minimierung von Formationsschäden
ISBN: 9786209353239 / Niemiecki / Miękka / 2025 / 68 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Unterbalanciertes Bohren (UBD) ist definiert als ein Zustand, der entsteht, wenn der effektive Zirkulationsdruck des Bohrflüssigkeitssystems in Kontakt mit dem Reservoirgestein geringer ist als der vorhandene Formationsdruck. Unterdruckbohrungen (UBD) werden eingesetzt, um Probleme im Zusammenhang mit Bohrungen, wie z. B. Formationsschäden, zu beseitigen oder erheblich zu reduzieren, da diese Probleme häufig zu einer erheblichen Verringerung der Öl- und Gasproduktivität in offenen horizontalen Bohrlöchern führen. Die Bedeutung der Minimierung von Formationsschäden ergibt sich aus der...

Planification du forage sous-équilibré dans un puits horizontal afin de minimiser les dommages causés à la formation
ISBN: 9786209355790 / Francuski / Miękka / 2025 / 68 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Le forage sous-équilibré (UBD) est défini comme une condition qui se produit lorsque la pression de circulation effective en fond de trou du système de fluide de forage en contact avec la roche du réservoir est inférieure à la pression de formation existante. Le forage en sous-pression (UBD) a été utilisé comme moyen d'éliminer ou de réduire considérablement les problèmes liés au forage, tels que les dommages à la formation, qui réduisent souvent considérablement la productivité du pétrole et du gaz dans la section horizontale à trou ouvert du puits. L'importance de...

Planning UBD in Hroizontal Well to Minimise Formation Damage
ISBN: 9783659713194 / Angielski / Miękka / 2015 / 68 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Underbalanced drilling (UBD) is defined as a condition which is generated when effective downhole circulation pressure of the drilling fluid system in touch with reservoir rock is less than presenting formation pressure. Underbalanced drilling (UBD) has been utilized as a mean to eliminate or significantly reduce the problem associated drilling like formation damage which is often this problem greatly reduce oil and gas productivity in open hole horizontal well section. The significant of minimizing formation damage results from the fact that wellbore pressure is intentionally maintained...
