Enterprise Products Partners' first-quarter crude oil pipeline volumes edged slightly higher, the pipeline and storage company said on May 2, helped by production growth in the top U.S. shale basin.

Enterprise has remained bullish on oil production from the Permian Basin, spread across Texas and New Mexico, and is looking to build a crude oil export terminal on the Gulf Coast to help push some of those barrels into the foreign market.

"Across our integrated system we continue to see crude oil, natural gas and NGL production growth from the Permian Basin," said Jim Teague, the company's co-chief executive officer, adding that domestic and international demand for U.S. energy and energy products remains resilient.

Total crude oil pipeline transportation volumes rose to 2.3 million barrels per day (MMbbl/d) in the three months to March 31, up from 2.2 MMbbl/d a year earlier, the company said.

Crude oil marine terminal volumes rose 5.7% to 841,000 bbl/d.

However, gross operating margin from its crude oil pipelines and services segment eased 4.3% to $397 million in the first quarter, partly due to expiration of minimum volume commitments on a key pipeline as well as lower average transportation fees and higher operating costs on others.

Overall net income rose 6.8% to $1.4 billion, or 63 cents per share.

The quarterly results represent "a healthy start to 2023 earnings," wrote Tudor Pickering Holt & Co analyst Colton Bean, and "bodes well for EPD's unofficial target of $9.3 billion" in full-year earnings before interest, taxes, depreciation and amortization.

Natural gas transportation volumes increased to a record 18.0 trillion British thermal units per day (Btu/d) in the first quarter compared with 16.4 trillion Btu/d for the same quarter last year.

Enterprise, however, warned that lower natural gas prices were beginning to temper activity and growth in dry natural gas plays such as the Haynesville and Eagle Ford.
