Abstract: Disclosed are compositions and methods for providing fluid-loss control in subterranean wells. Well-completion fluids contain fine particulate additives whose glass-transition temperatures are below the anticipated bottomhole temperature.

The additive may be supplied as a powder or in the form of a liquid suspension.

Abstract: A method for removing a fluid influx from a subsea wellbore drilled using a pump to return fluid from the wellbore to the surface. The method includes detecting the influx when a rate of the return pump increases. Flow from the wellbore is diverted from the return pump to a choke line when the influx reaches the wellhead. A choke in the choke line is operated so that a rate of fluid pumped into the wellbore is substantially equal to a flow rate through the choke line. Fluid flow from the wellbore is redirected to the return pump inlet when the influx has substantially left the well.

Abstract: Described is a well completion for evenly distributing a viscosity reducing injectant (e.g. steam and/or solvent, e.g. in SAGD or CSS) into a hydrocarbon reservoir (e.g. of bitumen), for evenly distributing produced fluids (most specifically vapor influx) and for limiting entry of particulate matter into the well upon production. On injection, the injectant passes through a limited number of slots in a base pipe, is deflected into an annulus between the base pipe and a screen or the like, and passes through the screen into the reservoir. On production, hydrocarbons pass from the reservoir through the screen into a compartmentalized annulus. The screen limits entry of particulate matter (e.g. sand). The hydrocarbons then pass through the slots in the base pipe and into the well. Where a screen is damaged, the compartmentalization and the slots in the base pipe limit particulate matter entry into the well.
