BP engineers have begun to slowly close theButterfly Valves last open valve on the cap installed above the company's leaking Gulf of Mexico well, which means that a critical integrity test is underway to determine if the well is in good enough shape to be sealed in at the top. At about 11:30 a.m., live feeds from the BP website showed that oil was still gushing out of the last open oil line, called a choke line. Officials plan to slowly close thisSafety valves last line over the next few hours, taking pressure readings as they go. Once the cap is sealed, the test could last 48 hours or longer. BP and government officials have agreed to analyze data and compare notes every six hours. Key information about the condition of the well could be available byGlobe Valves the end of the day and may offer hints about whether the oil may finally stop flowing. Experts will closely monitor pressure measurements. Low pressure may indicate that the well is leaking oil from other locations. If that is the case, the cap could exacerbate the flow from cracks in the well. In the worst-case scenario, oil could rise to the sea floor, creating new surface leaks. BP officials said that if they detect low pressure, they will unsealFilters the cap and revert to their oil collection plan, using a series of pipes leading to containment ships on the surface. But if the pressure readings are consistently high for 48 hoursAPI Cast Steel Valves -- indicating that they well may be strong and intact -- BP may keep the cap completely sealed. That decision will not be made immediately, however.

英国石油公司的工程师已经开始慢慢关闭最后对超出公司的泄漏墨西哥深井泵湾安装好帽子，这意味着，一个关键的完整性测试正在进行，以确定是否对身体好，好，是被密封在顶部开阀。在上午11:30左右，居住在英国石油公司网站供稿表明，石油仍然是喷涌而出的隔膜泵最后开放油线，称为阻塞线。官员计划慢慢关闭此在未来几个小时磁力泵的最后一行，回吐压力读数，因为他们去。一旦瓶盖是密封的，测试将持续48小时或更长时间。 BP和政府官员已同意对数据进行离心泵分析和比较注意到每6小时。关键信息的好可以由最终适用的条件和可能提供的石油是否可能最终停止流动的提示。专家们将密切注视的压力测量。低压可能表明该井从其他地方的石油泄漏。如果是的话，上限管道泵可能加剧从裂缝中的井流。在最坏的情况下，油价将上升到海底，形成新的表面泄漏。英国石油公司官员说，如果他们发现低压，他们将启封瓶盖和恢复他们的石油收集计划，利用一系列领先的管道表面上遏制船舶。但是，如果压力读数始终为48小时高 - 这表明他们也可能会较为强劲，完整 - 英国石油公司螺杆泵可能会保持完全密封的上限。这一决定不会立即作出，但是。
