... ABSTRACT A combined laboratory and field study was conducted to evaluate the susceptibility of Endicott Kekiktuk formation to acid stimulation treatments and to optimize treatment performance. Endicott crude oil causes severe sludging and emulsion problems when mixed with concentrated acids...

... indicate that the Si:AI ratio decreases as the acid moves through the core. Lowering the HF concentration decreases the Si:AI ratio and the rate of change of this ratio as the acid reacts with the formation. Increasing the HCI:HF ratio had little effect on the Si:AI ratio of the spent acid. Si:AI ratios...

The sand volume fraction was determined by preweighing the amount of sand and water. Samples were frozen to desired temperature before testing. A temperature probe...

(These counts did not distinguish SRB from non-SRB or live from dead bacteria; still, they indicate that the reservoir...

The lower concentrations were Newtonian fluids and the higher concentration ones pseudoplastics. A new kind of variable head rheometer was developed...
