When coiled tubing is run inside of conventional tubing it is often referred to as a velocity string and the space between the outside of the coiled tubing and the inside of the conventional tubing is referred to as themicro annulus. In some cases gas is produced up into the micro annulus.
Here's The First Instagram Photo Ever. Four years ago today on July 16, 2010, Instagram CEO and co-founder Kevin Systrom uploaded the first photo to the app, which was called Codename at the time. This picture of a golden retriever was taken at a taco stand called Tacos Chilakos, and the foot belongs to Systrom's girlfriend, according to a spokesperson for Instagram.
Instagram turns six today. Six years of people taking photos of their fancy cafe French toast, six years of #Fitspo, and six years of hating your friend that's over in Europe and won't stop gramming. To celebrate the six wonderful years it's been, we're gonna show you the first ever post that was done on the site. We warn you, it's nothing to write home about. Instagram founder Kevin Systrom was the first, and he posted the picture below of his dog and his foot. This very, very average image has 56.7K likes.
