The paper presents the technology used for extracting the energy of geothermal water that comes from a closed reservoir without decreasing the pressure of the reservoir. In order to do this, the reinjection of heat depleted geothermal water is obligatory. Therefore, beside the production well, an injection well is mandatory. Also, because of the high concentration of dissolved solids and to avoid...
Titian gas field has about 100m3/d gas condensate that is require to be transported to Pinghu integrated platform, then transported to Daishan terminal through Pinghu-daishan 16" oil sea tube. The platform is without storage means, Pinghu-daishan 16" oil sea tube has been in operation for 15 years, once Pinghu-daishan 16" oil sea tube or Daishan terminal has problem, the gas condensate...
The development of shale gas reserves is the current hotspot of oil and gas exploration and development at home and abroad. Correctly estimated reserves of gas reservoir has become increasingly urgent. The estimated of shale gas reservoir dynamic reserves in the past did not consider the influence of adsorbed phase occupies volume. In order to estimate the shale gas reservoir dynamic reserves exactly,...
New and advanced exploration, well drilling and completion technologies, like hydraulic fracturing and horizontal drilling, are allowing increasingly better access to non - conventional gas resources at competitive prices, and may have a big impact in global gas markets. This paper presents a review of the state of art and recent developments of unconventional gas production (tight gas, shale gas...
It is more profitable for the natural gas hydrate exploitation by use of the depressurization in conjunction with hot brine stimulation. In the work, at the initial stage of the exploitation, the depressurization is used to induce the hydrate dissociation. When the temperature drops and causes the decrease of the hydrate dissociation rate, hot brine is injected to prompt the hydrate dissociation,...
Hydrate self-preservation property has been reported by some researchers in recent years. So as to test the dissociation rate of hydrates in different temperatures and pressure conditions. The authors conducted laboratory experiments of methane hydrate dissociation in order to examine its potential for application to product natural gas from hydrate. The gas methane's used in this work were artificially...
The hydrocarbon deposits have stimulated worldwide efforts to understand gas production from hydrate dissociation in hydrate reservoirs well. This paper deals with the potential of gas hydrates as a source of energy which is widely available in permafrost and oceanic sediments. It discusses methods for gas production from natural gas hydrates. Authors provide a detailed methodology used to model gas...
