Oil Production Well Gas Separator System Using Progressive Perforations

A downhole gas-oil separator system for oil production wells, comprising:

• 1) a tubular cover having a specific length to diameter configuration, the tubular cover including:
• a) a first section comprising:
• i) a first group of 4 perforations equally spaced around the tubular cover, ii) a second group of 4 perforations equally spaced around the tubular cover, wherein the second group is located below the first group, and iii) a third group of 4 perforations equally spaced around the tubular cover, wherein the third group is located below the second group, and wherein each perforation of the first, second and third group measures 1 inch by 3 inches;
• b) a second section comprising:
• i) a first group of 4 perforations equally spaced around the tubular cover, wherein the first group of the second section is located below the third group of the first section, ii) a second group of 4 perforations equally spaced around the tubular cover, wherein the second group is located below the first group of the second section, and iii) a third group of 4 perforations equally spaced around the tubular cover, wherein the third group of the second section is located below the second group of the second section, and wherein each perforation of the first, second and third group of the second section measures 1 inch by 2 inches;
• and
• c) a third section comprising:
• i) a first group of 4 perforations equally spaced around the tubular cover, wherein the first group of the third section is located below the third group of the second section, ii) a second group of 4 perforations equally spaced around the tubular cover, wherein the second group of the third section is located below the first group of the third section, iii) a third group of 4 perforations equally spaced around the tubular cover, wherein the third group of the third section is located below the second group of the third section, and iv) a fourth group of 4 perforations equally spaced around the tubular cover, wherein the fourth group of the third section is located below the third group of the third section, and wherein each perforation of the first, second, third and fourth group of the third section measures 1 inch by 1 inch;
• and
• 2) a suction rod having a specific length to diameter configuration based on the tubular cover length to diameter configuration, the suction rod located within the tubular cover, wherein the tubular cover and suction rod are configured for coupling to a suction of a positive displacement pumping device located within production tubing.
