TECH REPORT COLOMBIA CARACARA SUR GOR, ft3/bbl [m3/m3] 200 [35,615] Electric Cost Optimization for ESP Saves Estimated Bubblepoint 150 pressure, psi [MPa] [1.03] USD 480,000 for Cepsa Bottomhole 1,200–2,300 pressure, psi [MPa] [8.3–15.9] Lift IQ service obtains real-time data to enable 16% reduction Pump setting 4,000–6,000 in electric costs during field test depth, ft [m] [1,219–1,829] 6,000–8,000 Well depth, ft [m] 18,000 [1,829–2,438] kW.h per month, before optimization kW.h per month, after optimization Using Lift IQ service, Schlumberger 16,000 monitored the ESP operational data for the 14,000 Caracara Sur field, evaluated the statistical Background 12,000 information, and also reviewed production With the current economic climate, the Schlumberger 10,000 trends, surface and downhole variables, well ASLC encouraged Compañía Española de Petróleos 8,000 intervention history, failure cause, and total (Cepsa) to evaluate system operations to increase 6,000 electric cost and consumption. efficiency. The installed ESPs were designed based 4,000 Based on this evaluation, Schlumberger on predicted reservoir and production conditions. 2,000 used DesignPro software and PIPESIM 0 However, at the current stage of production, the ESPs Well 1 Well 2 Well 3 simulator to optimize electric cost for the were encountering 90% water cut with motor load ESPs, reducing electric costs by 16% per of less than 45%, which made them inefficient and month across three wells—an approximate USD 6,951 savings of USD 79,000 per year.
