GWD vs AL (artificial lift) q The term GWD is broader & more inclusive; Ø Includes methods not normally considered AL; Ø Venting Ø VS ►Intermitting ►Swabbing Ø ESI (velocity strings) (extended shut-ins) Ø WHC (wellhead compression)? Ø While I believe the following are not solutions to LL, some may erroneously include them as GWD ü Water shut-off Jim Hacksma ►Choking 3

Suitability? q The following are very suitable in low rate gas wells for GWD; Ø PL ►Foam (sticks or liquid) Ø VS ►WHC Ø GL ►Swabbing Ø ESI ►Venting Ø SRP ü ►CGC (sucker rod pumping) Suitable only on wells making higher volumes of liquid q They Jim Hacksma can be used individually or in combination 4

Suitability? q The following are not usually suitable in low rate gas wells for GWD; Ø Hydraulic pumps (jet pumps & piston pumps) Ø ESP (electric submersible pumps) Ø PCP (progressing cavity pumps) q They Ø In ü general, they are designed for high liquid rates And loaded gas wells produce only modest liquid Ø In ü are used less commonly because; general, they have difficulty with gas Making them less than ideal for use in gas wells Jim Hacksma 5
