With the depletion of shallow-layer oil and gas pools inLiaohe oilfield, buried hill stratigraphic reservoirs in Liaohe oil field are becoming main objectives for exploration in recent years, especially in high-risk areas of Xinglongtai deep the Hing ancient buried hill resources are particularly rich. Since 2007, Liaohe oilfield increased investment for Buried Hill reservoirs with deep horizontal drilling developt the buried hill reservoir. Liaohe has completed 36 deep horizontal, with a total footage of 183920m, the average depth of 5109m. Improving drilling speed of "buried hill deep horizontal and branch horizontal wells”, and reducing drilling costs are of great urgency. “Hing buried hill deep horizontal, horizontal wells,” with composite drilling technology, supporting the optimization of PDC bits, the high-pressure jet drilling, the MWD borehole trajectory control and optimization of drilling parameters, the new drilling fluid technology and so on. With a large number of horizontal wells put into Buried Hill stratigraphic reservoirs, oil and gas production of average deep horizontal well increase of 2-5 times. Besides, the previous recovery and production of oil and gas reservoirs significantly improved to create an objective economic and social benefits.

Carrier-bed plays are an emerging type of unconventional oil play in which reservoirs are generally of low quality because they are characterized by: 1) thinly bedded heterolithic strata; 2) significant compaction and/or diagenesis; and 3) burrowing that has mixed sandstones and mudstone lithologies (i.e., heterogeneous lithologies). In this type of play, the carrier beds are pervasively hydrocarbon saturated and can be areally extensive (>50 mi2 or 130 km2). These low-quality reservoirs generally do not meet traditional petrophysical cutoffs and because of their high clay contents can have low resistivity, low contrast pays. The reservoirs may be composed of siliciclastics or carbonates or both. Due to reservoir quality and degree of oil migration, carrier-bed plays like the Codell are being developed with horizontal drilling and multistage hydraulic fracturing. Traditional vertical drilling yields marginal to uneconomic wells that can provide a clue to the existence of a carrier-bed play. The Codell Sandstone is a low-resistivity, low-contrast pay in parts of the northern Denver Basin. The area of oil and gas production is in the deeper part of the basin between and including Silo and Wattenberg fields of Wyoming and Colorado, respectively. The thickness of the Codell in this part of the Denver Basin ranges from 15 to 25 ft (4.5 to 7.6 m). Keys to Codell production are source rock maturity, and oil entrapment in the carrier bed. Oil in the Codell carrier-bed traps was generated in various intervals including the Niobrara (mainly the “B” marl), Sharon Springs Member of the Pierre Shale, Greenhorn/Carlile, and, rarely, the Mowry Shale.

Rail Service

Burgeoning oil and gas production in Texas with the application of hydraulic fracturing (fracking) and horizontal drilling techniques has dramatically impacted the condition of rural roadway infrastructure. Many rural roadways are now inundated with trucks traveling to and from oil and gas well areas. Recent estimates indicate that each horizontal well requires over 2,000 truckloads for construction, drilling operations, maintenance, and crude oil transport over the life of the well. Rail has been an active partner in oil and gas exploration by shuttling fracking sand and drilling supplies to the oil and gas regions and transporting crude and petroleum products from the regions not served by pipelines. This partnership is restricted by limited rail service points and infrastructure close to the active wells; however, expanding existing rail services and network infrastructure could move rail operations closer to the active production areas. The cost and safety impacts of extreme reduction in pavement life may be offset substantially with increased use of rail transport closer to drilling locations. This paper examines the potential options regarding expanded use of rail transportation to address the growing costs of roadway rehabilitation in energy production areas in order to reduce roadway network impacts. Rail service expansion can be through better use of the existing freight rail network, increasing the number of and better placement of transloading facilities along the rail network, and/or through improved rail capacity from double tracking or extending new rail lines. Both the private and public sectors potentially could play a role. A number of privately developed transloading facilities have sprung up along existing rail lines, attempting to deliver fracking sand, pipe, and other supplies. Additionally, public economic development corporations have been actively pursuing development. Expansion of the railroad network could come through the use of special districts such as Rural Rail Transportation Districts (RRTDs), Regional Mobility Authorities (RMAs), or through reactivation of abandoned rail lines. These trends are also examined.

Oil And Natural Gas

<p>The development of horizontal drilling and hydraulic fracturing has led to a steep increase in the U.S. production of natural gas and crude oil from shale formations since the mid 2000s. Associated with this industrial activity are emissions of ground-level ozone precursors such as nitrogen oxides (NOx). Satellite data are important in this context, because surface measurements are limited or non-existent in rural regions, where most U.S. oil and gas production operations take place. Here we use TROPOMI NO<sub>2</sub> observations to study NOx emissions coming from oil and natural gas production sites. Applying the divergence method we quantify basin wide emissions from well pad fields and aim to push spatial and temporal resolution of this technique. The divergence was method introduced by Beirle et al. (Science Advances 2019) to quantify point source emissions. It relies on calculating the divergence of the NO<sub>2</sub> flux to derive NOx sources and estimating the NO<sub>2</sub> lifetime to quantify sinks. Our analysis will include an assessment of different methods to constrain the NO<sub>2</sub> lifetime, which becomes particularly important when applying this method to larger areas. Further we will compare our results with bottom-up derived emissions. Here we use the Fuel-based Oil & Gas (FOG) inventory that calculates NOx emissions based on fuel consumption. Initial results show good agreement for the Permian Basin (NM, TX) and we will expand our analysis to other U.S. basins.</p>
