'gas preservation' is a correct and usable phrase in written English.
You could use it when discussing methods for preserving natural gas, such as storing it for future use or preventing losses of gas to the atmosphere. For example, "The company has implemented several strategies for gas preservation, including better leak detection and improved insulation of pipes."
Shale brittleness and ductility are key parameters for estimation of shale gas preservation and hydraulic fracturing.
The development of high-quality evaporite cap rock is highly favorable for oil and gas preservation.
The purpose is to roughly estimate shale gas preservation and hydraulic fracturing based on burial depth so as to lower geologic and engineering risks in exploration and production.
How to predict brittleness and ductility of shale is one of the key issues in the study of shale gas preservation and hydraulic fracturing treatments.
Brittle/ductile characteristics of shale are closely related to natural fractures, thus controlling the gas preservation and affecting the reservoir properties and compressibility (hydraulic response).
This timing is similar to gas expulsion and gas preservation of the Mount Goodwin source rock, which was the last event that has been established within the study area (Fig. 6).
For unconventional hydrocarbon, subsurface temperature pressure fields control the gas content, preservation conditions affect the critical time for hydrocarbon accumulation, and water potential and pressure result in accumulation in synclines.
The present paper reports a comprehensive investigation of maturity, reservoir properties, fluid pressure, gas content, preservation conditions, and other relevant aspects of the Lower Paleozoic shale from the Sichuan Basin and its surrounding areas.
The same restaurants that install expensive refrigerators and gas-injection preservation devices to care for their other bottles leave the sherries — if they even have any — in some warm, dusty corner of the bar.
It is favorable for shale gas accumulation and preservation.
After the completion of the surgery, bronchoscopy and arterial blood gases confirmed the preservation of bronchial blood flow and pulmonary function, and maintenance anesthetics and phenylephrine were discontinued.
