fracking

For more than 30 years, Henry Hub in Louisiana has anchored natural gas pricing in the Lower 48. But in the past 10 years, its role has shifted in profound ways. It has gone from a domestic benchmark pricing location for a vibrant Gulf Coast producing region to a demand-driven market and an index for U.S. LNG exports. In today’s RBN blog, we look at how Henry Hub became so integral to the workings of the emerging LNG market, both in the U.S. and globally. 

Ten years ago, U.S. exports of natural gas in the form of LNG were a footnote in the market. But that all changed in 2016. In February of that year, the first shipment of LNG from the Lower 48 states set sail when the vessel Asia Vision departed from Cheniere Energy's Sabine Pass export terminal in Louisiana. This was the culmination of a remarkable turnaround, not only at Sabine Pass, but for the U.S. natural gas market as a whole. Eight years earlier, Sabine Pass had been completed as an import terminal, as it was projected that the U.S. would face significant shortages of natural gas supplies. Shale turned that business model on its head. 

Drilling techniques originally developed to unlock oil and gas from shale formations are increasingly being adapted to access and extract heat from deep underground rock formations, enabling the generation of electricity from geothermal sources. And while geothermal’s share of total U.S. electricity generation remains quite small, it may be poised to accelerate, opening up new opportunities for companies in the oil and gas sector. In today’s RBN blog, we explain the basics of geothermal energy, its main advantages and drawbacks, and how U.S. expertise in oil and gas comes into play. 

Since its beginning in western Pennsylvania 166 years ago, the oil and gas industry has been on a relentless quest to unlock more hydrocarbons. And for years, the focus has been on drilling more productively, not just drilling more wells. The techniques that have evolved since the start of the Shale Revolution have led to rapid increases in the length of horizontal laterals, boosting initial production (IP) rates — a critical development but posing new challenges for drillers. In today’s RBN blog, we discuss why longer laterals in horizontal wells aren’t the answer in every shale play, the advantages of the two types of tubing used in those wells, and how they can help boost productivity. 

Oil and gas production in the Shale Era is a refined, controlled process — and a far cry from the early days of wildcatting a century ago. Modern drilling typically involves multiple wells on a single well pad, with each well going through a four-stage process to produce hydrocarbons that are then separated into distinct components. In today’s RBN blog, we look at how drilling-and-completion techniques have evolved over the years, from old-school vertical wells to the highly complex strategies targeting shale areas today, and how they set the stage for hydrocarbon production and recovery.

Over the past six years surging U.S. hydrocarbon production from shale has exceeded domestic demand in many cases – leading to the development of export infrastructure. Large volumes of natural gas liquids (NGLs) such as propane are already being exported. Natural gas exports in the form of liquefied natural gas (LNG) are about to start and the recent end to federal restrictions offers the possibility to increase crude exports if they become competitive. A critical assumption behind all these export opportunities is that the U.S. continues to be the only country (except Canada to a lesser degree) to successfully “crack the code” in shale exploitation to produce commercially significant volumes competitively. This assumption would be turned on its head if competing countries like Mexico, China, Poland, Argentina and the U.K. are able to unlock their own shale potential. Today we review RBN Energy’s first Drill Down report of 2016, which considers the many “below-ground” and “above-ground” factors that will determine whether and how quickly, shale development becomes a worldwide phenomenon.

A question we get asked all the time these days is whether or not U.S. crude output has begun to decline yet and if so by how much? We don’t actually think the answer makes a lot of difference to the market - especially when you consider changing imports and inventory. But ever since the OPEC meeting last November (2014) failed to take action to reduce  output to support oil prices - market watchers have placed a lot of emphasis on when U.S. shale producers would respond by cutting production. So regardless of the merits of the question we are all living in a marketplace where knowing the “real” state of U.S. production – and whether it is up or down – has become a big deal. To that end today we look at crude production data from the Energy Information Administration (EIA).

A few years ago, water-based or “hydraulic” fracturing emerged as a viable, cost-effective technique for coaxing large volumes of natural gas and crude oil out of U.S. shale formations. Calling it a game-changer is not an overstatement. In the shadows, another approach to fracturing was being developed, one that uses a liquefied petroleum gas (LPG) or propane gel and appears to offer some noteworthy benefits over tried-and-true hydraulic fracking. Today, we consider the potential for niche applications (and maybe much more) for fracturing that’s based on a hydrocarbon-based gel—not water.

The shift from diesel to LNG (and sometimes CNG or field gas) as a fuel for drilling rigs and hydrofracturing pump engines is underway, and there is interest in having ships, locomotives and long-haul trucks run on natural gas from LNG too. But before investing in new or converted engines that can run on natural gas or on a diesel-natural gas blend, diesel and shipping fuel users need answers to three questions: What will it cost? How much will we save? And—this is important, too--is the LNG infrastructure sufficiently robust to support the switch?Today we explore the economic ins and outs of converting from diesel to gas, and describe the current state of domestic LNG supply infrastructure.
