What's Happening at PEI
The United States oil and gas industry has reached unprecedented levels of production, setting new records and establishing the country as a preeminent energy superpower. This remarkable achievement is a result of relentless innovation, strategic policy decisions, and the industry's ability to adapt and thrive in a changing global landscape. The Pinnacle of Energy Dominance Recent data from the U.S. Energy Information Administration (EIA) illustrates a significant milestone in domestic oil production. In September 2023, the U.S. shattered previous records by producing over 13 million barrels per day. This feat was not a one-off event but part of an ongoing trend of increasing production, with subsequent months seeing even higher outputs. Technological Innovation and Efficiency A critical factor in this surge is the industry's investment in technology and efficiency. The adoption of hydraulic fracturing and horizontal drilling has unlocked vast reserves in shale formations. Meanwhile, improvements in operational efficiency have allowed for increased production even as the number of active drilling rigs has declined. This demonstrates the industry's capacity to maximize output from existing wells and continuously improve the cost-effectiveness of extraction methods. Regulatory Landscape and Policy Shifts The industry's growth has also been facilitated by a conducive regulatory environment. Key policy changes, such as the lifting of the export ban on U.S. crude oil, have opened up new markets and provided additional momentum. Moreover, the structure of land ownership and regulatory authority, particularly in states like Texas, has allowed for more nimble and responsive governance that supports industry growth. The Broader Impact The implications of America's energy dominance are profound. The U.S. is not only able to meet its own energy needs more reliably but also plays a pivotal role in global energy markets. This position enhances national security, contributes to economic stability, and provides leverage in international diplomacy. Looking Ahead As the industry looks to the future, the focus will remain on sustaining growth through innovation, strategic policy engagement, and maintaining a competitive edge in global markets. The expertise and resilience of those within the oil and gas sector are key to navigating the challenges and opportunities ahead. The United States' achievement in reaching and sustaining record levels of oil and gas production marks a significant chapter in the country's energy narrative. It reflects a collective effort across the industry—from the drillers on the ground to the executives making strategic decisions—to secure America's position as an energy leader on the world stage.

By focusing on custom, efficient, and environmentally responsible practices, they contribute significantly to the evolving landscape of renewable energy.
Many years ago spherical pigs were commonly used in natural gas pipelines to remove liquids – mostly water and condensates. The launchers were designed to only handle spherical pigs, using special valves such as the Wheatley Launch Valve and the Fitzpatrick Launch Valve. These resembled a check valve and were designed to release one spherical pig at a time by movement clapper with a lever. Then, with the implementation of Pipeline and Hazardous Materials Safety Administration (PHMSA) requiring that high pressure transmission lines be routinely inspected to prove integrity with inline inspection (ILI) tools, and with the installation of process equipment to remove these liquids, the spherical pigs slowly disappeared from the market. Today, however, with the drilling and development of the shale plays where producers found rich gas – containing large amounts of liquids such as butane, propane and ethane – the need to frequently pig to remove liquids has reappeared. The producers have learned that these rich-gas gathering systems are very profitable, but need to be pigged often – as many as four times a day – to keep production at high levels while capturing these liquids. Another factor that determines the pigging frequency is the amount of liquid being delivered with each pig run, compared to the amount of liquid that could be handled with the liquid separation equipment. If 500 barrels of liquid was delivered with each pig run, and the separation equipment could only handle 500 barrels, it would be necessary to pig the line daily. So, what pigs can be loaded several (10-12) at a time and released automatically on a timed basis or remotely, one at time, several times a day or a week, that can remove liquids? Hence, the reemergence of the spherical pig. Spherical pigs are hollow round balls, most are made from polyurethane, others from rubber products like neoprene. Most are inflatable and equipped with two 180-degree opposed molded-in inflation valves assembly. Today, there are also non-inflatable spheres appearing on the market. These require less pressure and less flow to move through a pipeline because they are not filled with liquid, have a thinner wall and vent holes to equalize pressure. The inflatable spheres must be filled and inflated with a liquid in order to hold their shape when exposed to high external pressure. With the use of an inflation pump the sphere is sized using a sizing ring at the pipe ID or slightly larger. They tend to roll and/or rotate while traversing a pipeline, which prolongs their wear life. Their wiping surface is all that touches the pipe and thus displaces most of the liquid within the pipeline. As a result, the wear life of an inflatable sphere will approach 1,000 miles.
