The UK Department for Transport (DfT) had observed that some petroleum road tankers contained defects in their circumferential welds, and these defects could increase the risk of failure during accidents. HSE SD were asked by the DfT to carry out…
The sequential excavation method (SEM) is extremely useful for excavating caverns with high sidewalls and large spans. A new SEM for excavating large-scale underground water-sealing oil storage caverns and protecting groundwater level is proposed.…
The prospects for CO2 sequestration in depleted shale gas formations are widely studied. Reported studies offer quantitative predictions of ultimate storage capacity as well as CO2 injection rate for a typical injection site or on an areal basis.…
During accidental crude oil spills and permitted discharges of produced water into the marine environment, a large fraction of naturally occurring oil components will be contained in micron-sized oil droplets. Toxicity is assumed to be associated…
As one of the important storage facilities for petroleum and petrochemical products, storage tanks are widely used by enterprises. With the increase of tank service time, tank deformation becomes one of the safety hazards of tank. The traditional…
In the process of heavy oil development, steam stimulation is usually used. In steam stimulation, the oil field is produced by depleted development after the end of shut in well. The magnitude of reservoir compressive coefficient is significant for…
This paper presents a detailed study of the SAGD dilation start-up technology, including the fundamental mechanism, numerical model, field operations, and well performance in PetroChina's Karamay "super" heavy-oil reservoir. Rock dilation refers to a…
Oil production at the field takes several decades. The timing of oil production is influenced by the properties of rocks and fluids and the technological parameters established by the design documentation. In general, it can be noted that as the rock…
The study aims to evaluate ground deformations in a vast area characterized by the coexistence of intense anthropic activities and offshore natural gas production. Onshore subsidence can be studied by GNSS, InSAR, high precision leveling and…
Sustained Casing Pressure (SCP) and production casing deformation in shale gas wells have been of growing interest in the industry, which should be attributed to the failure of cement sheath and casing respectively during the hydraulic fracturing…
Natural gas hydrate has become a hotspot for researchers because of its considerable economic benefits and potential strategic significance. In the hydrate exploitation process, the hydrate-bearing sediments get damaged, and the coupling effect of…
A major carbonate-cemented strata and carbonate concretions intercalated in the Early Miocene Kokozura Formation are common in the Izura area along the Pacific coast, in north Ibaraki, Japan. Chemotrophic mollusk fossils occur frequently with the…
In order to produce natural gas hydrate safely and efficiently, it is quite crucial to research the stability of hydrate reservoir in the process of its exploitation. The coupled thermal-hydrodynamic-mechanical (THM) numerical simulation can clearly…
The potential use of bio-binders as full or partial substitutes of petroleum-based binders have gained interest from the paving researches in recent years. Although there are many studies about rheological characterization of alternative binders,…
Based on the latest geological, seismic, drilling and outcrop data, we studied the geological structure, tectonic evolution history and deformation process of the southwestern Sichuan fold-thrust belt to find out the potential hydrocarbon exploration…
The safe transportation of waxy crude oil is a key in the field of pipeline gathering and transportation. The motion characteristics of an oil droplet in water for safe transportation are numerically analyzed in this paper. The mathematical model of…
Water-in-crude oil emulsions are formed as a result of high shear stresses at the flow restrictions such as choke valves and the wellhead during crude oil transport with produced water. Consequently, the produced water disperses in the crude oil…
