Many processes are used to produce an oil and gas reservoir. These processes can break down or create debris inside the wellbore creating blockages. Blockages are expensive and to avoid them, regular maintenance is necessary. A new tool developed by Blue Spark is the Wireline Applied Stimulation Pulse or WASP. This high-power acoustic wave device is used for post-fracking wellbore applications when the flow of oil is degraded by debris and scale build-up around wellbore perforations The WASP works by generating a high power electro-hydraulic discharge (EHD) within a transmission medium of water and salt (brine). The mechanical waves produced have a magnitude that pulverizes the built-up scale in the perforations of the well casing. It improves flow by re-opening adjacent well rock glazed and compacted by perforation charges, extending the wellbore lifecycle. WASP is a technology that ensures that existing wells function efficiently until all the available reserves are extracted. Blue Spark is the WASP developer and they have successfully deployed the system in many international settings and won two awards for the best technology development for oil and gas in 2015. Blue Spark is seeking a second collaborative applied research project with the Southern Alberta Institute of Technology (SAIT) to develop improvements to specific components of the WASP. The method that WASP employs is very effective at destroying debris around the well casing but the process is extremely hard on the WASP components. The electrodes and an isolating liner (that prevents contaminants from reaching the electrodes) are adversely impacted by the arc generation and degrade during the process. The degradation of these components is attributed to the extreme conditions in the downhole environment, the destructive mechanics of the EHD wave process and the requirement for electrodes to remain relatively clean and mechanically coupled to the environment around the tool.

许多过程用于生产油气储层。这些过程可在井筒内分解或产生碎片，从而产生堵塞。堵塞是昂贵的，为了避免它们，定期维护是必要的。Blue Spark开发的一种新工具是有线应用刺激脉冲或WASP。这种高功率声波设备用于压裂后的井筒应用，当油流被井筒穿孔周围的碎片和水垢堆积所降解时。WASP通过在水和盐（盐水）的传输介质内产生高功率电液放电（EHD）来工作。所产生的机械波具有粉碎井套管的穿孔中的累积水垢的幅度。它通过重新打开邻近井的岩石来改善流动，并通过射孔弹进行压实，从而延长井筒的生命周期。WASP是一种确保现有威尔斯井有效运行直到所有可用储量被开采的技术。Blue Spark是WASP的开发者，他们已经在许多国际环境中成功部署了该系统，并在2015年获得了两项最佳石油和天然气技术开发奖。 Blue Spark正在寻求与南阿尔伯塔理工学院（SAIT）进行第二个合作应用研究项目，以开发对WASP特定组件的改进。WASP采用的方法在破坏井套管周围的碎片方面非常有效，但该过程对WASP组件非常困难。电极和隔离衬垫（其防止污染物到达电极）受到电弧产生的不利影响并且在工艺期间退化。这些部件的劣化归因于井下环境中的极端条件、EHD波过程的破坏性力学以及对电极保持相对清洁并机械耦合到工具周围环境的要求。
