English units calculation

Barrels gained pumping slug, bbl

= (bbl slug pumped x slug wt, ppg mud wt, ppg) - bbl slug

Example: Determine the number of barrels of mud gained due to pumping the slug and determine the feet of dry pipe.

Mud weight = 12.6ppg

Slug weight = 14.2 ppg

Barrels of slug pumped = 25 barrels Drill pipe capacity = 0.01776 bbl/ft

Barrels gained = (25bbl x 14.2ppg 12.6ppg) - 25bbl = 28.175 - 25 = 3.175 bbl

Determine the feet of dry pipe after pumping the slug.

Feet of dry pipe = 3.175bbl - 0.01776bbl/ft = 179 feet
