Abstract
A method of drilling or gas-lifting is disclosed where the methods including the use of a foaming agent and a gas, where the foaming agent is a keratin and the hydrostatic pressure of the fluid in the well is for a portion of the drilling or gas-lift operation less than an hyrdrostatic pressure of the formation being drilled or under production.
Claims (10)
1. A method for drilling comprising the steps of drilling an oil and/or gas well with a drilling fluid including an effective amount of a foaming composition and an effective amount of a gas, where the foaming composition comprises at least one hydrolyzed keratin and the amounts are sufficient to reduce an hydrostatic pressure of the drilling fluid to a value at or below an hydrostatic pressure of the formation being drilled.
2. A method for drilling comprising the steps of drilling an oil and/or gas well with a drilling fluid while changing an effective amount of a foaming composition and an effective amount of a gas so that an hydrostatic pressure of the drilling fluid is maintained at a desired level at or below an hydrostatic pressure of the formation being drilled, where the foaming composition comprises at least one hydrolyzed keratin.
3. A method for drilling comprising the steps of drilling a first section of an oil and/or gas well with a drilling fluid, where an hydrostatic pressure of the drilling fluid is maintained at a desired level above an hydrostatic pressure of the formation being drilled, and drilling a second section of the well with a drilling fluid including an effective amount of a foaming composition and an effective amount of a gas so that an hydrostatic pressure of the drilling fluid is maintained at a desired level at or below an hydrostatic pressure of the formation being drilled, where the foaming composition comprises at least one hydrolyzed keratin.
4. A method for foaming a fluid comprising the steps of:
inserting at least one capillary coiled tubing into a well borehole to a desired depth below a fluid level in the borehole and injecting an effective amount of a foaming composition and an effective amount of a gas into the fluid to produce a foam, where the foaming composition comprises at least one hydrolyzed keratin and where the effective amounts are sufficient to decrease a fluid column weight increasing well fluids flow out of the well.
inserting at least one capillary coiled tubing into a well borehole to a desired depth below a fluid level in the borehole and injecting an effective amount of a foaming composition and an effective amount of a gas into the fluid to produce a foam, where the foaming composition comprises at least one hydrolyzed keratin and where the effective amounts are sufficient to decrease a fluid column weight increasing well fluids flow out of the well.
5. The method of claim 4, wherein the injecting comprises a single injection, multiple injections, periodic injections, continuation injections or mixtures or combinations thereof, depending on well requirements and desired flow rates.
6. A method comprising the steps of:
injecting into a downhole fluid an aqueous solution comprising a first effective amount of a foaming composition and an effective amount of a gas to produce a foam;
bringing the foam to a surface of the well;
adding a defoaming agent to the foam at the surface to break the foam and produce a two phase system;
separating production or organic fluids from the two phase system; and optionally adding a supplemental effective amount of the foaming composition to reform a foam, and repeating the injecting, bringing and adding steps, where the foaming composition comprises at least one at least one hydrolyzed keratin and where the effective amounts are sufficient to decrease a fluid column weight increasing well fluids flow out of the well.
injecting into a downhole fluid an aqueous solution comprising a first effective amount of a foaming composition and an effective amount of a gas to produce a foam;
bringing the foam to a surface of the well;
adding a defoaming agent to the foam at the surface to break the foam and produce a two phase system;
separating production or organic fluids from the two phase system; and optionally adding a supplemental effective amount of the foaming composition to reform a foam, and repeating the injecting, bringing and adding steps, where the foaming composition comprises at least one at least one hydrolyzed keratin and where the effective amounts are sufficient to decrease a fluid column weight increasing well fluids flow out of the well.
7. The method of claim 6, further comprising the steps of:
repeating the bringing, adding, separating and adding steps a desired number of times.
repeating the bringing, adding, separating and adding steps a desired number of times.
8. The method of any preceding claim, wherein the foaming composition further comprises at least one additive selected from the group consisting of sulfur scavengers, corrosion inhibitors, scale inhibitors, oxygen control agents, hydrocarbon accumulation agents and mixtures or combinations thereof, where the foam improves an activity the at least one additive and the additive may improve foaming characteristics of the at least one surfactant.
9. The method of any preceding claim, wherein the foaming composition further comprises a foaming additive selected from the group consisting of winterizing agents, foam boosters, anti-freeze agents, solvents, sodium salt of alpha olefin sulfonates (AOSs), acid salts, fatty acids, foam enhancers and mixtures or combinations thereof.
10. The method of claim 9, wherein the winterizing agents is selected from the group consisting of lithium formate, sodium formate, potassium formate, cesuim formate, triethyanolamine formate, and mixtures or combinations; the foam boosters comprise a cellosolve of the general formula R9OCH2CH2OH where R9 is an alkyl group having between about 2 and about 8 carbon atoms and mixtures or combinations; the anti-freeze agents selected from the group consisting of alcohols, glycols or other freezing point depressing agents and mixtures or combinations; the solvents selected from the group consisting of water, alcohols, ethers, esters or mixtures or combinations thereof; the sodium salt of alpha olefin sulfonates (AOSs) selected from the group consisting of short chain alpha olefin sulfonates having between about 2 and about 10 carbon atoms, longer chain alpha olefin sulfonates having between about 10 and about 24 carbon atoms and mixtures or combinations thereof; the acid salts selected from the group consisting of cyclamic acid salts such as sodium (cyclamate), potassium, salts of sulfonated methyl esters having between about 12 and about 22 carbon atoms, where the salt is sodium, potassium, ammonium, alkylammonium, salts of 2-aminoethane sulfonic acids, where the salt is an alkali metal, ammonium, or alkylammonium, and mixtures or combinations thereof; the fatty acids are selected from the group consisting of lauric acid, oleic acid, stearic acid and mixtures or combinations; and the foam enhancers are selected from the group consisting of a linear dodecyl benzene sulfonic acid salt, a sarcosinate salt, and mixtures or combinations thereof.
