Measuring pressure, temperature, flow and level in the pipeline is critical for midstream and upstream producers. When the pipeline is miles long, as many in the Texas Eagle Ford Shale, Bakken Shale and the Texas Permian Basin are, the quality of your process tubing, compression fittings and instrumentation is as critical as the pipeline itself to the profitability of the producer.

Instrumentation and process systems regulate interface levels in tanks to separate oil and water, so oil can be trucked to refineries for processing or to the nearest port for shipment. Faulty instrumentation or process systems can cause lower pricing for your product, as the oil is “contaminated” by excess water.

“Producers spend many millions of dollars to install the pipeline, X-ray the wells, and hydrotest the pipe. Correct, meticulous installation of process systems, tubing and compression fittings in the pipeline prevents lines from blowing or leaking – ensuring safe operations for staff, the community and the environment.” said Rolando Perez, Project Manager of Rabalais I & E Constructors’ Instrumentation & Systems Integration Division. “When oilfields become prolific, such as the Eagle Ford Shale has, many mechanical and roustabout companies enter the market to provide instrumentation and process tubing services. Unfortunately, many of these companies are unaware of the critical nature of correct insertion of the tubing and fittings. We’ve been called to remedy faulty installations time and time again,” said Darrell Harned, Vice President of Instrumentation & Systems Integration.

EOG On Track With 2015 Spending Plan

Talisman Cuts Jobs
EOG will resume fracking

EOG Resources released its first quarter earnings and operations report this week with hints about when they will return to fracking wells.

Citing low commodity prices, EOG announced a first quarter net loss of $169.7 million. They remain on track with their plans for a 40% capex decrease and are making substantial progress in reducing costs through operational efficiencies and service cost reductions.

85% of EOG’s spending for 2015 is allocated for the Eagle Ford, Delaware Basin, and Bakken. Their strategy is to continue drilling, but defer completions on a significant number of wells until oil prices improve. As oil prices recover, EOG predicts it will begin to begin fracking wells later this year when prices stabilize at around $65.

In an earnings conference call on Tuesday, Chairman and CEO, Bill Thomas announced that the first quarter results were “right on track” and that they are “quickly transforming the company to be successful in this low price environment.” Thomas went on to lay out the four basic objectives to EOG’s 2015 plan:

  1. Maximize 2015 returns on capital invested and position the company to resume strong growth when oil prices recover
  2. Focus on improving well productivity and operational efficiencies
  3. Protect the balance sheet by meeting our cash flow and CapEx expectations for the year
  4. Take advantage of opportunities during the down cycle to add acreage
We are using our exploration skills to define high quality acreage and are having good success capturing leasehold interest in emerging plays. Competition is down, acreage is available, and leasing costs are low compared to previous years, and we are optimistic more opportunities will materialize as the year progresses.
— Bill Thomas

EOG will reduce rigs in the Eagle Ford this year to 15 from 23 at year-end 2014 and will complete about 345 net wells. The company has  reduced completed well costs by 10% from an industry-leading $6.1 million average well cost in 2014 to a current well cost of $5.5 million.

 

Federal Fracking Regulations Challenged

Fracking Regulations Challenged

In March,the Bureau of Land Management (BLM) finalized new rules to regulate hydraulic oil and gas fracturing on public lands and challenges to that law began immediately. Last month, the Federal District Court of Wyoming cleared the way for states to challenge the sweeping federal authority to impose these regulations.

Texas has been facing the same issue on a more local level. The Texas ouse and senate recently approved legislation that favors state control that would would limit a city’s ability to impose regulations on oil and gas industry activities.

Colorado is joining Wyoming and North Dakota to challenge the new US federal government’s fracking rules and argue in their lawsuit that the new rules supersede the state’s authority and “invade” the jurisdiction of the state regulatory bodies. They also claim these additional rules aren’t necessary because the EPA has already granted authority to the states to monitor and protect underground water sources.

Colorado has robust regulations on oil and gas development, including hydraulic fracturing, and our agency regulators are doing a good job implementing them. I believe it is important to test BLM’s novel assertion of regulatory authority in an area that has been traditionally—and in this case expressly—reserved for the states.

Four Texas Quakes within 24 Hours

Four Earthquakes Rattle Irving

Another round of earthquakes hit north Texas this week, bringing the total number to 60 in the past year. The latest quakes were reported only two weeks after new evidence links fracking with increased seismic activity.

The United States Geological Survey is reporting a string of small earthquakes in Irving, a small community just northwest of Dallas. On May 3rd, two quakes measuring 3.2 and 2.5 magnitudes were registered about an hour apart and on May 4th, there were two more in the same area measuring 2.7 and 2.0 on the richter scale.

The USGS says that Irving and Northwest Dallas have experienced 60 quakes since April, 2014, but Brian Stump, a seismologist from SMU said that a more accurate picture reveals 388 seismic “events” so far this year in the area. The vast majority of these quakes are too small for people to feel, so they aren't making headlines. The quakes that have recently north Texas are small and cause minimal damage, but many wonder if all for this minor activity is a precursor to something more serious.

Before 2008, Texas earthquakes were rare, but have become much more commonplace.

The sad thing is that this is happening so often I’ve started to recognize it immediately. The first time I felt a quake back in January, I walked around for a good fifteen minutes trying to figure out what had happened.

Binational Energy Task Force in the Works

Binational Task Force
Binational Task Force

Since the Mexican government enacted historic energy reforms in 2014, there have been a flood of  initiatives to encourage dialogue and collaboration from both sides of the border. One if these is a new task force proposed by Texas Secretary of State, Carlos Casco.

Casco announced the formation of a new task force last week that will reach out to Mexican and U.S. agencies and entrepreneurs. His hope is that this binational effort will promote public/private partnerships to tackle critical issues that are key to economic development including infrastructure projects such as water and roads.

We have to invest in our infrastructure in order to continue being able to be a trading partner. At the end of the day, it’s about job creation and business on both sides of the river.
— Secretary of State, Carlos Casco

Mexico's new legislation opens up the country's energy market to foreign investment and has sparked the state power company (CFE) to initiate an aggressive construction campaign that includes $3.3 billion to be spent on 12 natural gas and electricity projects.
