A method for removing at least one contaminant selected from the group consisting of H S and CO from contaminating streams, including the steps of providing an above ground stream comprising hydrocarbon containing the at least one contaminant, and positioning metal-containing nanoparticles having a particle size of less than or equal to about 100 nm in the stream, the metal-containing nanoparticles being selected from the group consisting of metal oxides, metal hydroxides and combinations thereof, whereby the nanoparticles adsorb the contaminants from the stream.

Method for removing H2S and CO2 from above ground hydrocarbon streams

A method for heating a subterranean formation includes the steps of positioning a well to a subterranean formation; disposing an energy transforming material in the formation; and exposing the material to energy whereby the material generates heat.

Method for heating subterranean formation, particularly for heating reservoir fluids in near well bore zone

A method for treating a drilling fluid is provided, which method includes the steps of providing a drilling fluid, providing a drilling fluid additive in the form of superparamagnetic nanoparticles, mixing the drilling fluid additive with the drilling fluid so as to provide a treated drilling fluid, and exposing the treated drilling fluid to a magnetic field so as to recover the superparamagnetic nanoparticles.

Method for treating drilling fluid using nanoparticles

A method for altering wettability of a reservoir formation includes the steps of providing a water-based fluid containing a wettability altering coating system; and flowing the fluid into a reservoir so as to coat the reservoir with the coating system.

Water-based system for altering wettability of porous media

A method for sealing an annular space between a bore hole and a casing includes the steps of: providing a fluid sealing system comprising a particulate material and a bonding agent; positioning the fluid sealing system in the annular space whereby the particulate material adheres to walls of the bore hole and the casing; and curing the fluid sealing system so as to form a solid seal in the annular space.

Composition and method for sealing an annular space between a well bore and a casing

A method is disclosed for consolidating an unconsolidated formation, which method includes the steps of providing a well drilled to an unconsolidated formation, providing a consolidation fluid in the form of a fluid suspension of nanoparticles, and flowing said consolidation fluid through the well and into the unconsolidated formation so as to position the nanoparticles between grains of the unconsolidated formation whereby the formation is consolidated over time.

Method for consolidation of sand formations using nanoparticles

A method for drilling and completing a well includes the steps of drilling through a subterranean formation with a drill bit so as to form a well bore having a side wall; applying a consolidating material to the side wall under pressure so that said consolidating material flows into the side wall and provides a coated side wall coated with the consolidating material; and passing a scraping member having a desired profile past the coated side wall so as to provide the coated side wall with the desired profile an apparatus is also provided.

Method and apparatus for drilling and completing a well

A method for removing at least one contaminant selected from consisting of H S and CO from hydrocabon streams, including the steps of providing a stream of hydrocarbon containg the at least one contaminant; the positioning metal-containing nanoparticles in the streams, the metal-containing nanoparticles being selected from the group consisting of metal oxides, metal hydroxides and combination thereof, whereby the nanoparticles absorb the contaminants from the stream.

Method for removing H2S and CO2 from crude and gas streams

An apparatus for performing a function in a flowing fluid includes an apparatus body and a drag member associated with the apparatus body. The drag member is configurable between drag configuration for moving with the fluid wherein the apparatus has a first drag and a reduced drag configuration for moving against the fluid wherein the apparatus has a second drag which is less than the first drag.
