  • UBL Y well K cluster at PT. Pertamina Geothermal Energy Ulubelu Area is chosen as research object. It is a two-phase well with liquid dominated system which produces steam and brine. In this research, it is a well that cannot secrete fluida automatically (non artesian). To find out production capability of well – that is the magnitude of its production rate and enthalpy fluida of various pressure in head well, production test analysis is chosen for this research. Flat lip method is chosen because it is applicable to new well for exploration drilling phase where not only to find out description of potential wells, but also to determine total enthalpy score (H) with inadequate well facilities. To get total enthalpy score (H) and production capability score or deliverability of UBL Y well K cluster, thus calculation is done using Russel James equation based on what is parameter needed when using flat lip test. There are eight parameters, head well pressure, lip pressure, brine height on wear box, height of wear box from its base to V-notch lip, wear box width, lip pipe diameter, pipe lip diameter, pipe area size and maximum discharge press. With mentioned parameter data well deliverability score can be known using Russel James equation.
