This viscoelastic behavior  results from its large, complex, molecular  compounds that create dense, viscous hydrocarbons.  Subsurface bitumen fields require secondary  recovery processes to reduce viscosity and produce  the hydrocarbons. Heat is one of the primary  techniques. The change of velocity in the reservoir  should be a function of the temperature and  production of the bitumen. This thesis has two  lines of investigation to aid in understanding the  temperature and frequency dependency of  viscoelasticity in bitumen and bitum-saturated  rock, and from that, to assist others in  interpretation of their time-lapse seismic data. Along the first line of investigation, this  research made lab measurements to estimate  velocities as a function of temperature and  frequency of the Canadian Grosmont formation  reservoir rocks.The thesis measurements focused on  two sets of samples: a) homogeneous, dolomite core  plug, which was grain-supported and b) smaller  heterogeneous reservoir samples, which were bitumen- supported.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838387604\"\u003e\u003ch3\u003eLab Measurements on Heavy oil and Bitumen\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838387604","offer_id":39469233406045,"sku":"9783838387604","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/62cb9131-4101-4a74-b224-3a750f482392.jpg?v=1774936509","url":"https:\/\/shop.autorenwelt.de\/products\/temperature-and-frequency-dependence-of-viscoelasticity-in-bitumen-von-merrick-johnston","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
