Isicathulo sentambo ye-Watermelon singelinye lamathuluzi okugaya ekusebenzeni kokuchezukisa. Isetshenziselwa ukulungisa i-casing, ukulungisa kabusha kanye nokuvula iziteshi. Ngokuvamile isetshenziswa ngokushesha ngemva kokuvula amafasitela. Unqenqema lokugaya (indawo yokusebenza) yesigayo sekhabe luthinta udonga lwe-borehole, futhi ukuphela konqenqema ngalunye kuklanywe njengekhoni. Lapho iwindi livulwa, isigayo sekhabe singanweba iwindi ukusuka phezulu futhi sisuse ukukala kanye nama-burrs asele odongeni lwamapayipi ngesikhathi sokusika kokuqala.
