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.

油气藏的开采采用了多种工艺。这些过程会破坏或在井筒内产生碎屑，造成堵塞。堵塞是昂贵的，为了避免堵塞，定期维护是必要的。Blue Spark开发的一种新工具是电缆应用刺激脉冲（WASP）。WASP的工作原理是在水和盐（盐水）的传输介质中产生高功率电液放电（EHD），这种高功率声波装置可用于压裂后井筒中，当油流被井筒射孔周围的碎屑和结垢破坏时。产生的机械波具有粉碎套管射孔中堆积垢的量级。它通过重新打开相邻井，通过射孔药对岩石进行抛光和压实，从而提高了流动性，延长了井筒生命周期。WASP是一种确保现有油井有效运行直到所有可用储量被开采的技术。Blue Spark是WASP的开发商，他们已经成功地在许多国际环境中部署了该系统，并在2015年获得了两项最佳油气技术开发奖。
