An easy to use application that will estimate time remaining until achieving total depth and calculate pump volumes for duplex and triplex mud pumps. Time until total depth is estimated by inputing total depth, current depth, stand length, connection time, survey time, rate of penetration and trip time.Pump volumes for duplex pumps are calculated by inputing pump efficiency, rod diameter, liner diameter, stroke length and strokes per minute. Triplex volume calculations uses the same information except for the rod diameter. Output is in gallons and barrels per stroke and output per minute in gallons and barrels.
