Greene’s Energy Group receives patent for closed gas buster separation system and method

Greene’s Closed Loop Separator.

Greene’s Energy Group, LLC (GEG), a diversified oil service company and leading provider of integrated testing, rentals and specialty services, has been awarded a United States patent for its Closed Loop Separator, a step change in safety and solids handling for the oil and gas industry.

This third generation system increases safety by preventing the release of gas on location during well completion and intervention operations. Gas separation is optimized significantly with the addition of a 10-inch diameter internal gas buster tube (more surface area for gas breakout) and an 8-inch diameter vertical vent (minimizes velocity spillover and reduces mist carryover).

With the gas buster enclosed in the tank, the system can be completely sealed, is self-pressurized, safely contains all gas, and is able to securely transmit gas to the vent or flare. Further safety features of the system include level safety low/high shutdown controllers on the primary separator and a secondary level safety high shutdown controller on the gas buster (both are key safety differentiators on flowback operations).

Greene’s Closed Loop Separator is specifically designed for high solids applications through reduced fluids velocity. This is accomplished by large diameter chambers for phase separation and quiet zone baffling.

As a new standard for safe and efficient fluid handling, the Closed Loop Separator provides a four-phase hydraulic or atmospheric separation for gas, oil, water and solids and can be used in many onshore and offshore applications, including well stimulation and flowback operations; well intervention projects – including coiled tubing, wireline and pumping – including subsea wellhead to surface operations including flowlines, risers and umbilicals; and commissioning and decommissioning operations – including pipeline flushing, cleaning and testing. The separator can also be used to replace in-line platform production equipment for routine maintenance or equipment replacement periods.

With an 85 barrel tank and a 40 psi operating pressure, the Closed Loop Separator features include:

  • H2S Certified
  • BSSE Compliant
  • Site glass level indicators conveniently placed for monitoring all phases (bbls in/out)
  • Oil Bucket with 3 adjustable weirs
  • High flow rate capacity, 6-8 bbls/min with 24 bbls/minute surge capacity
  • Internal gun lines
  • High solids capacity w/ real time evacuation of solids under pressure
  • Can be integrated with production flow process to control produced water flow (self-throttling)

“This new technology is a game changer in production and completion fluid separation – for operations and the environment,” said co-inventor Elwin Faulk, Vice President / General Manager Water Treatment Services. “The internal gas buster not only optimizes separation by slowing velocity and breaking down the fluids and solids faster, but when followed by additional filtration, ensures clean water is safely deposited back into the offshore environment.”

  • The Closed Loop Separator provides a four-phase hydraulic or atmospheric separation for gas, oil, water and solids and can be used in many onshore and offshore applications.

Proposed pipeline protection eases environmental concerns

Pipeline-related oil spills are costly and cause public outcry. A new construction and operation method using double-wall pipes may help ease those concerns.

Pipelines move millions of barrels of petroleum products around North America in any given year. Most of the time, the process is entirely uneventful – oil goes in one end of the line and comes out the other at its destination.

Trelleborg identifies sealing materials to extend seal life in high fire risk oil & gas hydraulic applications

Alternative sealing materials, such as Zurcon Z80 and in particular Zurcon Z13 could offer better wear resistance and extended life in HFC fluids.

Due to the different chemical makeup of HFC and HLP fluids, sealing materials proven and traditionally used with HLP fluids, though effective in HFC applications, do not necessarily provide effective performance or length of life in HFCmedia. In tests, Trelleborg Sealing Solutions has identified sealing materials that offer extended life in HFC applications.

Predictive models stop spills before they happen

The use of specialized software is expanding, with more and more kilometres of pipe being looked at before problems arise.

According to the Canadian Energy Pipeline Association’s 2015 Pipeline Industry Performance Report, there are more than 110,000 kilometres of transmission pipeline in Canada that move more than 1.2 billion barrels of liquid petroleum products and 5.3 trillion cubic feet of gas each year. On those pipelines last year, there were 122 spills or releases reported, four of which were classed as significant by industry standards – and that’s just main transmission lines. There are many more kilometres of smaller pipes criss-crossing oil and gas fields across the country.
