Defining a Horizontal vs. a Vertical Well Bore Blue = Vertical Red = Horizontal Black ~ depends Feb. 17-20, 2013 2013 Gas Well Deliquification Workshop Denver, Colorado 20
When is the Black Profile a Vertical or Horizontal Well Bore? Tubing Diameter = small Gas Volume Rates = high Liquid Rates = moderate Black profile is considered to be a vertical for the purpose of launching soapsticks, i.e., 1 soapstick and minimum shut-in time. Blue = Vertical Red = Horizontal Black ~ depends Tubing Diameter = large Production Rates = low Liquid Rates = high Black profile is considered to be a horizontal when treating the well with soapsticks, i.e., multiple sticks, longer shut-in for volume build. 21
Conclusions and horizontals that -- Vertical Completions -- are re-classified as vertical Launch one soapstick at a time As often as the liquid loading requires Minimal shut-in period -- Horizontal Completions -- Shut-in the well Launch one or more soapsticks Build volume ~100 psi over line and verticals that are beginning to decline Feb. 17-20, 2011 2013 Gas Well Deliquification Workshop Denver, Colorado 22
