The following five definitions relating to primary care should be taken together.

Where The U.S. Gets Its Oil. America is one of the world's largest oil producers, and close to 40 percent of U.S. oil needs are met at home. Most of the imports currently come from five countries: Canada, Saudi Arabia, Mexico, Venezuela and Nigeria.
Texas. Texas is the U.S. top producer of crude oil and natural gas, according to the U.S. Energy Information Administration. The stateâs oil production increased by more than 500,000 barrels a day in the year to September. The increase was mostly thanks to production in two formations, Eagle Ford in South Texas and the Permian Basin in West Texas. In September, Texas crude-oil production hit 2 million barrels per day.
