NEW MODEL ADDS PRECISION TO GAS-LIFT DESIGN

R.A. Kendrick Hampton Resources Inc. Houston A.H. Woodyard, J.W. Hall Conoco Inc. Houston Conoco Inc.'s new analytical technique for lift gas allocation identifies, in one-pass, injection rates and the achievable mandrel location for injection. The injection depth is first fixed at each mandrel location and a nodal analysis is used to establish a range of possible injection and production rates. The mandrel-specific response curves are combined to create the well's total response curve.
