Control Green House Gas (GHG) Emissions with Multiphase Pumping
GHG emissions from oilfield production are getting a lot of attention in media and in industry discussions. It is taking a hard look at the conventional production site or pad with tank batteries, separators, flares, compressors, pumps and other process equipment. One focus is on CO2 produced from combustion in engine driven generators and pumps, heater treaters and trucks necessary for service and transport of water and hydrocarbons.
The second focus is on methane, which is much more potent as GHG compared to CO2. Methane has a tendency to escape from a number of seepage points in stock tanks, separators, valves, seals and stuffing boxes.
One obvious way to reduce GHG from oil & gas production is to limit the size and the amount of equipment at the production site or pad and find ways to transfer the entire production to a centralized processing facility. With as few processing centers as possible, which are gathering production from multiple sites, the exposure and chances to GHG releases are minimized and can be easily monitored and controlled.
Here is where multiphase pumping comes in. Besides its ability to lower wellhead pressures for added totally recovery it is able to gather and pressure boost the multiphase flow (oil, water and gas) in a single flow line downstream to a distant processing and treatment facility.
In essence, it could reduce the equipment needed at the production site to just well testing and pressure boosting.
The multiphase pump can be direct driven from a natural gas engine using produced gas as fuel. Compared to other boosting and AL methods such as ESP or gas lift, the energy efficiency of a direct drive multiphase pump is superior as no generators; VFD’s or line losses have to be taken into account.
In summary, multiphase pumping can contribute to overall reduction of GHG reduction in addition to its other many benefits.
