Pressure control is a primary concern in the safety of wireline worksites, including oil and gas wells. To maintain stable, safe pressure, you'll need an equalizing assembly, along with locking mandrels. Working in tandem, these two devices help to control pressure and optimize subsurface flow to keep your site operating as safely and smoothly as possible.
In addition to controlling pressure and flow, an equalizing assembly can have other benefits as well. Most notably, it can eliminate sand bridges and natural gas hydrates within your well. In scenarios involving low temperatures and high pressure, natural gas can combine with water to create these hydrates, which act somewhat like ice. Natural gas hydrates and sand bridges can create hazards within the well, potentially damaging your downline equipment, so it is in your best interest to prevent them from forming.
