Geomechanical evaluation of reservoirs in the coastal swamp, Niger delta region of Nigeria

International Journal of Advanced Geosciences, 2018
Evaluation of elastic parameters of reservoirs can be used in geomechanical modelling, wellbore stability analysis, and sanding, which can be applied in practical situation to optimize drilling, completion and productions of wells. Petrophysical analysis was done to identify various reservoirs in two wells, using sonic, neutron, gamma, resistivity and ...

Conditions of sedimentation in the Sarskoye Swamp (Yaroslavl region, Russia) in the Late Glacial and Holocene

Limnology and Freshwater Biology, 2022
Abstract. A comprehensive lithological analysis of bottom sediments from the central part of the Sarskaya depression was carried out. We determined that a shallow lake existed in the Sarskaya depression as least from 22500 to 12400 years ago. The bottom sediments potentially contain traces of global climate change - in particular, a presumable trace of

Physiological refugia: swamps, hypoxia tolerance and maintenance of fish diversity in the Lake Victoria region

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2002
In Lake Nabugabo, Uganda, a satellite of Lake Victoria, approximately 50% of the indigenous fishes disappeared from the open waters subsequent to the establishment of the introduced predatory Nile perch, Lates niloticus. This pattern is similar to the faunal loss experienced in the much larger Lake Victoria.
