32 | bhge 2018 form 10-k baker hughes rig count the baker hughes rig counts are an important business barometer for the drilling industry and its suppliers .
when drilling rigs are active they consume products and services produced by the oil service industry .
rig count trends are driven by the exploration and development spending by oil and natural gas companies , which in turn is influenced by current and future price expectations for oil and natural gas .
the counts may reflect the relative strength and stability of energy prices and overall market activity , however , these counts should not be solely relied on as other specific and pervasive conditions may exist that affect overall energy prices and market activity .
we have been providing rig counts to the public since 1944 .
we gather all relevant data through our field service personnel , who obtain the necessary data from routine visits to the various rigs , customers , contractors and other outside sources as necessary .
we base the classification of a well as either oil or natural gas primarily upon filings made by operators in the relevant jurisdiction .
this data is then compiled and distributed to various wire services and trade associations and is published on our website .
we believe the counting process and resulting data is reliable , however , it is subject to our ability to obtain accurate and timely information .
rig counts are compiled weekly for the u.s .
and canada and monthly for all international rigs .
published international rig counts do not include rigs drilling in certain locations , such as russia , the caspian region and onshore china because this information is not readily available .
rigs in the u.s .
and canada are counted as active if , on the day the count is taken , the well being drilled has been started but drilling has not been completed and the well is anticipated to be of sufficient depth to be a potential consumer of our drill bits .
in international areas , rigs are counted on a weekly basis and deemed active if drilling activities occurred during the majority of the week .
the weekly results are then averaged for the month and published accordingly .
the rig count does not include rigs that are in transit from one location to another , rigging up , being used in non-drilling activities including production testing , completion and workover , and are not expected to be significant consumers of drill bits .
the rig counts are summarized in the table below as averages for each of the periods indicated. .
