Shale Gas Operations: Lifting Requirements by Stage

Shale gas and natural gas extraction involves four core stages—drilling, fracturing, gathering, and liquefaction—each placing distinct demands on lifting equipment, from large-tonnage lifts to precision explosion-proof handling.

Drilling (rig assembly, horizontal drilling, casing running, cementing) follows conventional oil and gas practices but with longer horizontal sections (1,000–3,000 m) and higher wellhead pressures (35–70 MPa). Derrick heights reach 45–60 m, calling for 250 t-class petroleum special cranes (API 8C certified).

Fracturing (pump skids, blender trucks, instrument trucks, manifolds) is unique to shale gas operations. A typical fracturing spread spans 30–50 m in length and weighs 200–400 t in total, with individual pump trucks weighing 35–50 t. These require 50 t-class heavy-duty cranes or truck-mounted cranes for on-site assembly and maintenance. The fracturing site is a high-pressure zone (70–100 MPa), and crane operating areas must remain at least 10 m away from high-pressure manifolds.

Gathering (wellhead collection stations, dehydration, boosting) requires lifting capacities of 10–32 t. When hydrogen sulfide (H₂S) is present in the gas, equipment must use sulfide stress cracking (SSC)-resistant materials. Recommended solutions include explosion-proof Ex d IIB T4 electric hoists with stainless steel, sulfide-resistant hooks. Given the tight equipment spacing in gathering stations, explosion-proof KBK flexible systems are the preferred choice.

Liquefaction (purification, liquefaction, storage, loading) demands low-temperature cranes, as LNG storage tank areas operate at -162°C. This calls for Q345E low-temperature steel (impact energy ≥34 J at -40°C), low-temperature seals rated to -196°C, and low-temperature lubricating oil (pour point ≤ -50°C).

Kelude Heavy Industry supplies lifting equipment across the entire shale gas value chain—from large-tonnage petroleum special cranes for drilling to low-temperature explosion-proof hoists for liquefaction plants.
