Sum of oil surface flowrate and water surface flowrate :

Symbol	Metric unit	Oilfield unit
	cmd	bpd

It is related to Total sandface flowrate as:

q_L = q_O + q_W = \frac{q_t}{B_w Y_w +[ (B_o - R_s B_g] + B_g (GOR-R_s)] (1-Y_w)}

Starting with definition of Total sandface flowrate and substituting the expression of Oil surface flowrate, Gas surface flowrate, Water surface flowrate through Liquid production rate one arrives to .
