1. A slickline is a nonelectric cable used for selective placement and retrieval of tools and flow-control equipment in a wellbore. This cable passes through pressure-control equipment mounted on the wellhead, permitting a variety of downhole operations to be conducted safely on live wellbores.
2. The bubblepoint is the temperature and pressure at which part of a liquid begins to convert to gas. Thus, if a constant volume of liquid is held at a constant temperature while pressure is decreased, the point at which gas begins to form is the bubblepoint.
3. The dewpoint is the temperature and pressure at which a gas begins to condense. If a constant pressure is held on a given volume of gas while the temperature is gradually reduced, the point at which droplets of liquid begin to form is the dewpoint of the gas at that pressure.

8. Oilphase-DBR is the fluid-sampling and analysis division of Schlumberger. Oilphase was founded in Aberdeen in 1989 with the launch of the industry's first single-phase, cased-hole, bottomhole sampling tool. Oilphase was acquired by Schlumberger in 1996. DBR was founded in 1980 in Edmonton, Alberta, Canada, by Donald Baker Robinson, the coauthor of the Peng-Robinson equation of state. DBR designed and manufactured mercury-free PVT and flow assurance laboratory equipment, equation-of-state software, and heavy-oil fluid analysis services. In 2002, DBR was acquired by Schlumberger and merged with Oilphase.
9. As a pressure transient diffuses into a formation, it is no longer affected by wellbore and near-wellbore effects, and becomes more indicative of formation properties. This period is often called the infinite-acting radial-flow regime because the transient is unaffected by external boundaries and thus acts as if it is infinite in areal extent.
10. The rate at which a fluid passes through a component is a function of its retention time.
