Shale gas formations are “unconventional” reservoirs – i.e., reservoirs of low “permeability.” Permeability refers to the capacity of a porous, sediment, soil – or rock in this case – to transmit a fluid.
Drilling for Shale Gas - MIT Technology Review
2013年1月2日 · After drilling a well, a worker prepares the rig to be moved to another site. The drill bit above, made of tungsten carbide and synthetic diamonds, was designed for the shale.
Chevron Shale and Tight Resources
Development of natural gas and oil resources from shale and tight rock involves a number of steps. These include obtaining permission to drill from the landowner and government, constructing a temporary drilling site, and using a rig to drill the well.
Horizontal well-drilling technology for shale-gas formation
2024年1月1日 · This chapter introduces the international development status of shale-gas horizontal well-drilling technology, as well as site designs for drilling cluster horizontal wells, batch drilling technology, factory drilling rig, and 3D horizontal well …
New Drilling Technology of Shale Gas and Tight Gas
2020年7月12日 · Foreign countries are still in the monopoly position in the core shale gas drilling technologies, such as rotary steerable system, geosteering, high-performance water based drilling fluids, high efficiency PDC bits, and automatic drilling rigs.
Drilling, Completing, and Producing from Oil and Natural Gas Wells
It starts with preparing the site (clearing and leveling) and setting up a drilling rig to drill a borehole and feed steel pipe into the well. Drilling mud is used to manage downhole pressures, provide information about the rock layers being drilled through, and keep the drill bit cool.
Drilling Productivity Report - U.S. Energy Information Administration …
The Drilling Productivity Report (DPR) rig productivity metric new-well oil/natural gas production per rig can become unstable during periods of rapid decreases or increases in the number of active rigs and well completions. The metric uses a fixed ratio of estimated total production from new wells divided by the region's monthly rig count ...
Shale gas - Wikipedia
Shale gas tends to cost more to produce than gas from conventional wells, because of the expense of the massive hydraulic fracturing treatments required to produce shale gas, and of horizontal drilling.
Multiwell pad drilling technology for shale gas reservoirs: …
2024年1月1日 · Due to the advantages of easily regulated rheology, convenient for field performance maintenance, and particularly the low cost and mild environmental impacts, high-performance water-based mud (HPWBM) is gradually replacing OBM as the preferred option for shale gas drilling.
Research on slim-hole drilling technology for shale gas …
2024年9月1日 · This paper focuses on coring technology and drilling safety, summarizing a set of high-efficiency shale gas drilling equipment and technology systems based on geological drilling equipment and techniques (that can be used for solid mineral exploration).
