Paper Number: SPE-175749-MS
... Abstract Tight gas reservoir development has long been affected by 1) complex flow profiles and 2) the impact of very low permeability on reservoir productivity. Where well tests (WT) buildup is very short, interpretation becomes difficult and results often are ambiguous. Most WT of tight, dry...

... The production of hydrocarbons from reservoirs, after well completion, might not be always economical because of various reasons, such as high wax content in oil deposition of scale or asphaltenes or very low permeability of reservoir rock. For oil with high wax content methods, such as steam...
