Method and apparatus for enhancing production from an oil and/or gas well

A method of producing oil and/or gas firm a well having a wellhead near the earth's surface, a wellbore, and an oil bearing formation within the earth that surrounds the wellbore, comprising the steps of;

• a) providing a wellbore that is lined with casing having a flow bore and a lower end portion that is positioned to receive oil and/or gas flow from the oil bearing formation within the earth;
• b) placing a production pipe inside the casing to provide an annulus between the casing and the production pipe, the production pipe having a bottom portion that extends to an elevation that is positioned next to the oil hearing formation and an upper end that is positioned next to the wellhead;
• c) enhancing the production of oil and gas via the production pipe by reducing pressure at the top of the production pipe and throughout the production pipe;
• d) wherein in step “c” the pressure at the bottom portion of the production pipe is atmospheric or above;
• e) assisting in the lift of fluids from the wellbore in the production pipe and/or annulus with a means that is secondary to step “c”;
• and
• f) wherein the bottom portion of the production pipe is fully submerged during steps “c”, “d”, and “e” and pressure at the lower end portion is atmospheric or above.

A method or producing oil and/or gas from a well, comprising the steps of;

• a) providing a well bore that is drilled into tho earth for communicating with an oil bearing formation and lined with a hollow, fluid transmitting casing that extends into the earth, wherein said casing has an a flow bore, top and bottom portions, and wherein the bottom portion is positioned close enough to the oil bearing formation to enable fluids to flow into said casing from said oil bearing formation;
• b) placing a production pipe inside the casing to provide an annulus between the casing and the pipe;
• c) enhancing the production of oil and/or gas via the production pipe with a production enhancement that reduces pressure at the top of the production pipe and throughout at least another part of the production pipe;
• d) wherein in step “c” the pressure at the bottom of the production pipe is atmospheric or above;
• e) assisting in the lift of fluids from the well bore with a second production enhancement that is not the production enhancement of step “c”;
• and
• f) wherein the bottom of the production pipe is fully submerged during steps “c”, “d”, and “c” and pressure at the bottom of the production pipe is atmospheric or above.

A method of producing oil and/or gas from a well, comprising the steps of;

• a) providing a well bore that is drilled into the earth for communicating with an oil bearing formation and lined with casing that extends into the earth, wherein said casing has upper and lower end portions, and wherein the lower end portion of the casing receives flow of oil and/gas from the oil bearing formation;
• b) placing a production pipe inside the casing to provide an annulus between the casing and the production pipe the production pipe having top and bottom portions;
• c) enhancing the production of oil and/or gas from the well bore via the production pipe with a plurality of production enhancements, including at least one that reduces pressure at the top portion of the production pipe and throughout the production pipe;
• d) wherein in step “c” the pressure at the bottom portion of the production pipe is atmospheric or above;
• e) assisting in the lift of fluids from the well bore with a second production enhancement that is not the production enhancement of step “c”;
• and
• f) wherein said bottom portion is fully submerged during steps “c”, “d”, and “e” and pressure at the bottom portion is atmospheric or above.
