Presentation Overview:
Poor perforation efficiency and excessively high bottomhole treating pressures are subsurface problems that lead to increased pumping costs and cluster over-capitalization in the range of $400,000/well upfront. This is before taking into account the lost reserves which in current designs can be worth in the range of $100,000/cluster throughout the life of a well's production.
Historically, most technologies that offer a way to evaluate these issues have been either highly invasive, expensive, or unreliable which is why in 2022, Seismos, in conjunction with a major operator, went about field testing a new acoustic based alternative that only requires high rate sensors located at the wellhead. Through numerous wells, including those with bottomhole gauges and permanently cemented fiber, the acoustic friction analysis of rapid planned and unplanned rate drops (5 bpm+) was validated in its ability to deliver accurate real-time measurements of pipe friction and perforation friction - a crucial step towards the proper calculation of perforation efficiency and its time dependent counterpart, uniformity.
The presentation will walk through these validations and specific use cases from the Permian Basin.
