Houston Researcher Begins Phase 2 of Corrosion and Cathodic Protection Scale Study

Brine Chemistry Solutions is beginning phase two of a project researching corrosion and scale prediction. The corrosion and cathodic protection study will examine prevention in extreme pressure and temperature environments that could make drilling operations in the Gulf of Mexico safer and more productive.

Brine Chemistry Solutions, a Houston-based researcher of water chemistry issues in the energy industry, announced it has begun phase two of a research project that will evaluate corrosion and scale prediction and prevention at extreme pressure and temperature (xHP/HT).

Phase one of the research involved conducting experiments with instrumentation capable of studying corrosion and scale formation at up to 24,000 psi and 250°C (482°F). Phase one produced methodology and data that will be used in phase two to further develop the company’s models.

Phase two will include additional xHP/HT testing of corrosion and scale in additional alloy types and complex brine systems and will screen multiple inhibitors for thermal stability and effectiveness.

Brine Chemistry Solutions will use an autoclave reactor, proprietary flow-through apparatus, and vertical scanning interferometry to focus on kinetics and behavior at xHP/HT while simultaneously studying the thermal stability of inhibitors.

Modeling during phase two will also focus on solvent behavior in electrolytes that have specified chemical properties and will expand to include the quantification of kinetic factors during water-ion and ion-ion interactions. Modeling will incorporate the equation of state based on statistical associating fluids theory.

 “The corrosion and scale research being performed by Brine Chemistry Solutions is good for the Gulf of Mexico,” said Glenn Shreffler, executive vice president, engineering at MATCOR, a  cathodic protection company that specializes in providing customized corrosion engineering and cathodic protection systems to oil and gas and other industries.

“There are a literally hundreds of oil and gas production wells in the gulf but there’s not a lot of data about corrosion and scale in deepwater, extreme pressure and temperature environments,” Shreffler said. “That means this research has the potential to provide a great deal of information, including  predictive models, that will help us help our customers enhance production and improve safety and reliability.”

The corrosion and scale research is part of a larger, $4.5 million project that was awarded to Brine Chemistry Solutions by the Research Partnership to Secure Energy for America.


MATCOR’s Durammo™ Deep Anode System Provides Enhanced Performance

As we reach the home stretch of 2013, well drilling continues to advance at a strong pace, thanks to improvements of drilling technology. Advanced horizontal and directional drilling has opened a range of possibilities for energy companies and local economies. Along with the improved drilling technology, MATCOR has helped advanced the cathodic protection technology for wells.

Properly configured deep well anode systems are an integral portion of reliable cathodic protection wells. For deep well anode systems, which output less than approximately 75 amps, MATCOR has designed the Durammo™ continuous mixed metal oxide (MMO) wire anode systems to provide second-to-none value for those in need of high-quality cathodic protection systems.

Essentially, there are two basic types of anode configurations:

Discreet Anodes
Here, several individual anodes are placed a minimum of ten feet apart throughout the system in order to avoid mutual anode interface effects. In this configuration, it is not abnormal to have 10 or 15 discreet anodes throughout the system (old technology).

Continuous Anode Assembly
In MATCOR’s deep anode assembly system, Durammo™, a continuous wire that is fed from a cable at each is used in lieu of many individual anodes. In order to create electrical redundancy, factory connected jumper cables are installed to the wire anode every ten feet. This arrangement effectively eliminates risk of mutual anode interference.

Additionally, MATCOR’s Durammo™ Anode System is made with MMO as opposed to graphite or high silicon cast iron to create a light, stable anode that has the capability of operating at higher current densities. They also use MATCOR’s Super-Vent™ pipe assembly to enhance overall venting capability and cabling with a chlorine-resistant PVDF layer for protection.

Overall, for deep well systems with outputs under 75 amps, MATCOR’s Durammo™ technology provides superior value through several performance enhancements and greater longevity.

Utica Shale – Plans For A New 38 Mile Natural Gas Pipeline

Utica Shale News: A Columbia Gas sister company released plans  to build a 38-mile pipeline that will transport natural gas liquids from Ohio’s Utica shale.

Pennant Midstream said the pipeline will connect the Hickory Bend processing plant in Mahoning County to the Utica East Ohio Kensington plant in Columbiana County. It will cost about $60 million and have the capacity to deliver 90,000 barrels per day.

This is one of several projects in northeastern Ohio that will provide ways to get natural gas liquids such as ethane and propane to market. The liquids have a wide array of uses; among them, ethane is a key ingredient in chemical manufacturing, and propane is a fuel for home heating.

The liquids often need a dedicated pipeline, the construction of which is an important part of developing the Utica, said Ben Ebenhack, associate professor of petroleum engineering at Marietta College.

“You don’t want to move vast quantities of liquids in a gas pipeline,” he said. “They will tend to accumulate in the pipeline and block the flow of the gas.”

The Utica is rich in liquids, which is helping to drive much of the investment there.

While the market price of natural gas has been low for several years, the liquids sell for a much higher price.

Pennant Midstream is operated and co-owned by a subsidiary of NiSource, which is the Indiana-based parent company of Columbia Gas of Ohio.

“The construction of new infrastructure is critical to unlocking the potential of the Utica shale play in Ohio,” Jimmy Staton, Columbia Pipeline Group and NiSource Midstream Services CEO, said in a statement.

“This partnership will not only provide a key link in that infrastructure, it will provide economic-related benefits for companies and residents of Ohio and the Appalachian basin.”

Harvest Pipeline Co., a subsidiary of Houston-based Hilcorp Energy Co., also co-owns Pipeline Midstream. Steve Jacobs, president of Harvest Pipeline, said the project is “an important milestone in advancing the development of the Utica shale.”

Construction has already begun on the project, with plans to finish by July.


Pipeline Cathodic Protection News: New Spectra Natural Gas Pipeline Construction

Pipeline cathodic protection industry received a boost this week: proposed high-volume natural gas pipeline construction across 3 Southeastern states. Spectra, the company behind this jolt of economic opportunity, has dubbed it the “Renaissance Project”. The natural gas pipeline proposes several lines branching off the main pipeline to potential customers along the route.

The pipeline is a complex project and will require a number of business services such as pipeline cathodic protection. MATCOR’s pipeline protection program uses a number ISO 9001:2008-certified solutions to protect such a project. For example, MATCOR’s SPL™-FBR linear Anode and Durammo™ Deep Anode System would help lower total cost of ownership on the pipeline.

The proposed pipeline is almost 300 miles with three different pipeline diameters. The natural gas pipeline will feature two compressor stations to maintain line pressures, according to officials. It was stated the line will have a capacity of 1 billion cubic feet per day, and can be expanded to over 1.5 billion cubic feet per day.

Spectra plans for the pipeline to run from the Chattanooga, Tennessee area, through Alabama and towards the Atlanta, Georgia area. “We are continuing to work with multiple potential customers to design a project to fit their supply demand needs,” Grover said in a statement on the project.

Furthermore, Spectra executed letter of intent with the AGL, the parent company of Chattanooga Gas Co., and Atlanta Gas Light explore a joint arrangement for local distribution. Sources close to the matter state the “Renaissance Project” could be up and running by mid-2017.

“From a project kickoff standpoint, we continue to reach out to federal, state and local public officials informing them of the project,” she said. “We’ll send letters and start contacting landowners along our proposed study corridor pending further market feedback.” Grover stated Spectra the Renaissance Project study corridor map is in the final stages. Currently, the map highlights 15 counties across Tennessee, Alabama and Georgia.

Economic groups across these states laud the move as one that will stimulate the economy and bring jobs to the region. “It’s going to be a good project and the infrastructure for natural gas is such that, industry-wide, there’s a great demand for it,” one source familiar with the matter said. Experts familiar with the project say it is a crucial move to support industrial expansion and business growth in the region.


MATCOR’s Insight That Works

The Renaissance pipeline is indeed poetically named. The Southeastern region has recently seen improvements to its economic state and industrial competitiveness. However, key investments such as the natural gas pipeline and other infrastructure must be put in place to attract jobs, manufacturers and families into these committees. That said, the pipeline is a key cog to the continued rebirth of this region. MATCOR and other service providers will be stewards of this bright future, protecting valuable assets that power communities.

Natural Gas Transmission Pipelines & Safety: Major Washington Expansion

The Washington State natural gas transmission pipelines and safety landscape received a big announcement this week. Multiple sections of pipeline in Washington will be expanded, according to federal filings by Northwest Williams Pipeline.

The current gas transmission pipelines are 30 inches. The proposed expansion will place 36 inch pipeline next to the old 30 inch pipeline. The construction, expected in early 2017, will also create continuity between existing 36 inch pipeline. The pipeline expansion is a perquisite for a new liquefied natural gas (LNG) export station in Astoria. The project will encompass a wide range of work, including natural gas pipeline safety and protection.

In total, the pipeline project will span 140 miles from the Oregon state and Canadian national borders. The Oregon Pipeline Company will connect the southern expansion into Oregon through an installation underground the Columbia River. The finished product is LNG that will be shipped to Asia from the Astoria natural gas terminal.

Northwest Williams Pipeline estimates the project cost at $870 million. Upon completion, the pipeline will be made available to other customers in the Northwest, including Washington and Oregon. The company also stated it expects the pipeline to generate over $10 million in property taxes, per year across Washington.

The Federal Energy Regulatory Commission (FERC) received the application request in June. FERC officials have announced the plan will be reviewed in tandem with the Oregon LNG pipeline plans.


MATCOR’s Insight That Works

The proposed pipeline expansion holds a great deal of promise for all involved. The Astoria LNG terminal is poised to service rapidly expanding markets in Asia.  Northwest Williams Pipeline will help bring a great deal of economic benefit to Washington. At the same time, the project is highly complex by joining multiple existing pipeline sections. Natural gas pipeline safety and pipe protection are large concerns. The company is making a large investment that will require expert cathodic protection to secure continued profit. Technology such as linear SPL anodes could make a huge impact for Northwest Williams Pipeline.

New 234 Mile Natural Gas Pipeline Coming to New Mexico

The federal government gave the green light to a proposal to build 234 miles of gas pipeline to transport natural gas liquids from one corner of New Mexico to the other and ultimately to markets in South Texas.

News of the pipeline’s approval encouraged oil and gas developers in New Mexico, which is home to portions of both the Permian and San Juan basins.

“These projects aren’t just built for the conditions at the moment. They’re long-term investments,” said Wally Drangmeister, a spokesman for the New Mexico Oil and Gas Association. “I think it’s a good sign that some investment is going in that will support the state.”

The project will transport natural gas liquid products from northwestern New Mexico to a hub in Hobbs in the southeastern corner of the state and ultimately to Texas.

With production increasing in the San Juan Basin and in the Rocky Mountains, Mid-America Pipeline Co.’s existing system is nearing capacity. Currently, the system can transport about 275,000 barrels per day, but more wells are going into production in New Mexico, Wyoming, Utah and Colorado


Another New Pipeline for Texas will require Cathodic Protection

Texas continues its frenzied activity of chemicals, energy and cathodic protection of pipelines. Dow Chemical Company announced this week a full service chemical pipeline from the Houston area to East Texas. Wood Group Mustang will provide construction and support services for this project.

The pipeline runs from Freeport and Mt. Belvieu, Texas. Asset management and maintenance of the pipeline will be a requirement. Some of those regulations include pipeline cathodic protection for almost 140 miles between the Dow Texas facilities.

The pipelines and station upgrades are part of Dow Chemical’s expansion of its ethylene unit. Dow’s recently announced a detailed plan to capitalize on booming supplies of shale gas in North America.

This contract includes a wide spectrum of field services, construction management and engineering (including Cathodic Protection).  Wood Group Mustang has provided similar services for Dow Chemical on previous projects. The project will be overseen through its Houston and Angleton, Texas offices. The project is estimated to reach completion in 2016.


Matcor’s Insight That Works

Dow Chemical has recently started a turnaround in its Texas operations. This is exciting for both Dow and the related service industries. As Dow ramps up its chemical and ethylene operations, services such as cathodic protection for pipelines will also see a lift. In short, this investment will build more than a pipeline. The communities and local economies around this pipeline are sure to see a boost from Dow, Wood Group Mustang and their contractors.
