INDUSTRIAL GAS SUPPLY AND SERVICES FOR THE OIL & GAS INDUSTRY
Growing your reserves
From enhanced oil recovery projects in southern Mexico to gas well fracturing (fracing) in Canada, our commitment to reserve growth spans the globe. Continued development of natural gas and oil reservoirs is critical to meeting your company’s business plan objectives — and Praxair’s industrial gases and field services help you do just that. We have over 30 years of experience providing services in enhanced oil recovery, energized fluid fracing, and well injection services. Additionally, as a leading supplier of nitrogen and carbon dioxide, Praxair is your one-stop partner for optimizing your oil and gas production.
INDUSTRIAL GASES FOR THE OIL & GAS INDUSTRY
Nitrogen
The oil industry has five main enhanced oil recovery applications that utilize nitrogen, including pressure maintenance, miscible displacement, immiscible displacement, gas assisted gravity drainage (GAGD), and mixed gas, which increases reservoir reserves. Nitrogen is also used as an energized fluid to fracture shale or other unconventional formations to produce tight gas and oil reservoirs.
Carbon Dioxide
It is well-known in the oil industry that carbon dioxide can be applied to your reservoir as a tertiary oil recovery method. At Praxair, we can provide CO2 injectivity testing, pilot applications and full-field projects. We also provide CO2 services for energized fluid fracturing (fracing) in conventional reservoirs for both long reach horizontal and vertical wells.
NDUSTRIAL APPLICATIONS FOR THE OIL & GAS INDUSTRY
Well Fracturing
We’re helping you produce conventional and unconventional hydrocarbons through fracturing. We supply liquid nitrogen and carbon dioxide, as well as industrial services such as product transport, storage vessels, and booster pressure pumping.
Enhanced Oil Recovery
Our industrial gas injection systems are proven, cost-effective and smart ways to get more oil and gas out of your reservoirs. We have the expertise to understand your enhanced oil needs and the ability to develop low cost, reliable gas supply systems to meet your particular needs. We have supplied gases to over 20 EOR projects. And we’ll work with you to design, build, own and operate a complete gas system for nitrogen or CO2.
Inerting Thermal Events
We supply CO2 for inerting thermal events in large contained areas such as coalmines, coal silos and grain elevators. Our experienced team has twenty years of experience and offers CO2 sourcing, portable pumping equipment, and quick mobilization and response.
Nitrogen Applications
We provide high-pressure nitrogen at the wellhead, which is used for the following applications:
-
Annulus Insulator
-
Coiled Tubing
-
Completion
-
Drill Stem Testing
-
Foam Acid
-
Foam Cement
-
Hydra-Jetting
-
Lost Circulation Control
-
Mud Lightening
-
Pressure Testing
-
Stuck Drill Pipe
INDUSTRIAL SERVICES FOR THE OIL & GAS INDUSTRY
CO2 Well Stimulation Services
At Praxair, we offer well pad storage and CO2 pumping with our dedicated fleet of up to 60-ton storage vessels, manifolds and boost pumps with remote operation. We are a leader in gas supply logistics and liquid sourcing. And our highly skilled industry technicians, engineers and field supervisors work closely with service providers and owners to ensure each frac job is executed flawlessly. We can also provide technical assistance in energized fluid frac design with E-Frac simulation.
Pilot CO2/N2 EOR Services
Reservoirs in a mature primary or secondary stage of production are candidates for gas displacement recovery applying CO2 or N2 injection. To determine if your reservoirs are amenable to this service, we use geological analysis and computer modeling to understand which strategies will work best. But before investing in the infrastructure necessary to enhance recovery on your full field, we offer smaller scale pilot testing services. We’ll provide short to medium term — typically one to 36 months — supply, delivery and pumping of CO2 or N2 to your fields to enable pilot testing.
We are a leading U.S. provider of oil field services for both CO2 and N2. And we have the experienced field engineering and technician crews required to safely and reliably deliver and operate our well site equipment. We work with customers to determine the best mode of operation and will provide the equipment and expert crews to execute the pilot tests.
Huff n’ Puff Services
Our cyclical Huff n’ Puff services stimulate aging oil wells with CO2 to recover tertiary oil. In this process, CO2 is injected into a single well. The well is shut-in for a designated soaking period and the CO2 dissolves into the oil to cause swelling, increased saturation and permeability, and reduced viscosity. Oil is then produced back from the stimulated well typically at a higher rate than before treatment.
Nitrogen Supply & Pressure Pumping
Praxair has the supply infrastructure, storage and pumping equipment, and expert crews to meet your high-pressure nitrogen needs for any oil or gas well application. We deliver liquid nitrogen to the well site in truck mounted storage vessels and have high-pressure pumps which deliver liquid at high-pressures needed for your unique applications. We also have direct fired and heat recovery vaporizers to convert liquid N2 to gas at the desired discharge temperature.
As the largest industrial gas company in North America, Praxair has an extensive liquid N2 production and delivery network to meet our customers’ needs in all geographies. Our experienced crews provide on-site set-up and operations of our storage and pumping equipment.
NiCool® Accelerated Reactor Cooling System
NiCool® cools most reactors to less than 40 degrees Celsius in under 20 hours and consumes substantially lower quantity of nitrogen when compared to traditional once-through cooling methods. Praxair also brings decades of operating experience and trained personnel who can help you run the system safely, efficiently and with reduced operational costs. The NiCool® service employs a computer program to model your reactor system and predict liquid nitrogen injection rate, volume, and time required for cool down.
NiCool® service equipment is designed for automatic control of the cool down process given a specified cool down rate, by maintaining an appropriate injection rate and liquid nitrogen velocity. The system is also equipped with automatic fail safe features for shut down in case of temperature variation or system malfunction, thereby ensuring low temperature protection of your reactor system.
We do more than provide industrial gases, applications and services specific to the oil & gas industry. We will help you to optimize every step of your process. From consultation to implementation and use, we offer a range of industrial services that help you deliver your project on time and on budget so you can be as productive and efficient as possible.
