In a CHOPS (Cold Heavy Oil Production with Sand) application near Elk Point, Alberta our Client was experiencing short run times on a well that was recompleted in May of 2017. The well was making 5-6m3 of oil daily for the first 6 months after recompletion. The well steadily declined over the next few years and has settled into a marginal rate below 1m3 of daily oil. Overall water cut was relatively low over this time with little to no water being produced. On the normalized production plots below, the LS Pivotal pump was installed in the 6th month.
The previous PCP installed in this application ran for 4.5 months. The Client was looking for options to increase run time and decrease workover frequency in order to improve the economics on this well.
The patent pending Lifting Solutions PivotAL PC Pump was evaluated as a viable option to reduce the frequency of tubing pulls effectively decreasing workover costs. A model 10-1200x2 PCP was deployed on October 27, 2017 and began producing around 6m3/day of total fluid with 87% oil, 6% water and 7% sand. Monthly updates over the course of the next 8 months are summarized in the table below.
The installation of the PivotAL pump was considered a technical success as the pump efficiency was restored by the rod lift operation. There was a positive run time performance increase from 4.5 months up to 8 months. This equates to a reduction in servicing frequency from 2.7 times/year or $40,000/year down to 1.5 times/year or $22,500/year based on an average workover cost of $15,000. This is a potential savings of $17,500/year.
