Natural gas has two faces. On one side, it is an important part of the energy-transformation toolkit. On the other side, it is a potent greenhouse gas. Technology can bring the two sides together.

The three papers selected for this Tech Focus feature describe technologies that can make natural gas safer to move and store.

The first paper, OTC 30655, describes an effort to eliminate flaring during offloading from a floating liquefied natural gas facility (FLNG) and an LNG carrier. Managing the balance of fuel gas and boiled-off gas between the FLNG and the carrier is vital to maintaining equilibrium and eliminating flaring. The paper looks at carriers with spherical tanks and presents a process study to identify potential causes of flaring during offtake and corrections that could eliminate it without capital modifications.

The second paper, OTC 30871, considers the benefits of barges over ship-type LNG carriers. Ship-type LNG carriers are designed to operate offshore over fields, which does not necessarily provide optimal opportunity for monetization. The paper argues that near-shore barges holding liquefaction facilities linked to the rest of the system elsewhere could be a more-viable gas-monetization concept.

The third paper, SPE 204787, describes a characterization and monitoring approach for underground gas storage. The approach involves close integration of subsurface understanding with the optimization of surface facilities. It also addresses sustainable operations through an asset-integrity-management plan.
