经常问的问题

What is API’s Weekly Statistical Bulletin (WSB)?

API的力是一个每周调研报告石油data (crude and products). It is a survey of U.S. refiners, bulk storage and blending terminals, pipelines, and importers. This includes data related to refinery operations, along with production; imports; and inventories of the five major petroleum products:crude, motor gasoline, kerosene jet fuel, distillate fuel oil,残余燃料油。

When is WSB published?

API’s WSB is published every Tuesday afternoon at around 4.30pm (or on Wednesday at 4.30pm if Monday is a Federal Holiday). Additionally, WSB may be published on a different day during special holidays (e.g., Christmas or New Year). For the most up-to-date WSB schedule, please go toapi.org.

DO API和能源信息管理局(EIA)发布估计数或人口普查数据?

API和EIA都不会收集100%的每周调查数据。API和EIA都在记录中指出,他们报告的每周数据涵盖了该行业的90%,并发布只估计every week.

API在哪里获得其WSB数据(数据收集)?

API收集美国跨美国石油和天然气公司的数据。WSB的调查参与者都是API成员和非成员。API收集提交给EIA的数据的确切副本。为了减少对受访者的报告负担,API使用相同的EIA每周调查表格,并提供与EIA相同的报告方法。因此,API遵循EIA的收集时间表和截止日期。

How does API identify its survey respondents (sample design)?

API’s WSB – similar to the EIA’s Weekly Petroleum Status Report (WPSR) – is an estimate calculated from survey responses. The sampling procedure used for the weekly surveys is the cut-off method; which is the same procedure used by EIA. API targets the largest to the smallest companies on the basis of their refinery and storage capacity. API maintains a high response rate of about 90% depending on the product and location.

Given that API’s survey is voluntary, are API estimates reliable and accurate?

虽然公司自愿发送API将其发送到EIA的数据副本,但该事实不会影响所收到的信息的可靠性或准确性。API和EIA都在记录中指出,他们报告的每周数据占该行业的90%。API和EIA只需要估计其余10%。

为什么API的数据有时与EIA的数据不同?

API和EIA样本和调查约90%的行业,估计其余10%。它们的样本覆盖范围和估算过程可能不同,这有助于其每周发布数据的差异。但是,由于API和EIA只需要估计10%,因此每周估计的差异可以很大程度上归因于统计噪声。

How does API calculate the remaining 10% of the industry (non-sample estimation)?

Once the data quality is assured, the remaining task for API is to use the 90% response rate data to estimate the data for the remaining 10% of the industry. API uses a combination of trend, seasonal, cyclical, and imputation methods to reach an estimate for the industry.

API的WSB估计是否准确?

Yes, in 2020, when looking at recent data for Crude, Gasoline, and Distillate stocks, API and EIA have been within 1% of each other about 75% of the time. API urges analysts and reporters to verify the WSB data accuracy by comparing it to the EIA definitive numbers in their Petroleum Supply Monthly.

谁使用WSB报告?

WSB报告被能源交易员和石油公司广泛使用。

我在哪里可以购买WSB?
