... Abstract Even though the downhole gauges and wellhead meter (wet gas meter) have been invented decades ago, having them installed in every wells are still considered as a luxury for many companies. However, does this view still reasonable for a tight gas reservoir let alone located in a remote...

... Technical work description, finding and recommendations Abstract A robust estimation of the Expected Ultimate Recovery (EUR) for fracture stimulated multi-layered tight gas wells, early in the production life of the wells, is the cornerstone for a meaningful project economic analysis, reserves...

... Abstract Keshen gas field, located on the northern margin of the Tarim basin, Western China, is an unconventional sandstone tight gas reservoir with extreme reservoir conditions: ultra-deep, low porosity, low matrix permeability, high temperature and high pore pressure. In order to gain...

... a well is approaching abandonment rate. The WHC can remain on the well for the remaining life and, once production ceases, be moved to another well. This paper provides a case study for the successful application of WHC in a mature gas field, comprising a combination of conventional and tight gas...

... Abstract Tight gas plays an important role in the increasing production of natural gas. Staged hydraulic fracturing has been a key technology to make recovery of tight gas economically viable. The JP formation of Western-Sichuan Gas Field is a typically tight gas reservoir with horizontal wells...

... Abstract This reservoir is a tight gas field and the target sand stone zones are generally staged fracturing treated at depths of roughly 1500 to 2800 meter. Knowing the direction or azimuth of the fracture orientation is important in development of this low permeability reservoir...

... Abstract In order to evaluate development plan of unconventional tight gas reservoir in production stage, Rate Transient Analysis techniques can be utilized to get estimates of OGIP, EUR, SRV, and relevant information, which are based on boundary-dominant flow analysis. In this study, various...

... Abstract Sulige gas field is a typical tight gas reservoir with the features of low-pressure, low-permeability and low-abundance. Its gas-bearing condition is bad so that the economic benefit is not good. To improve the well performance and economic benefit, an applicable well-plant operation...

... reserves have shown annual growth. This highlights the understated potential in the area and the under-lying difficulty in quantifying the true value of a tight gas well early in its life. This difficulty generally arises from the challenge of forecasting multi- layered reservoirs with variable surface...

... Abstract Initial period of production from a fracture stimulated tight gas sands can alter stress distribution around the hydraulic fracture. This allows a new fracture to reorient along a different azimuth, even up to 90 degrees, thereby providing access to less depleted zones and retrieving...

...-permeability reservoirs, the pseudo-steady state (PSS) flow condition dominates the production life of a well, and therefore modeling of production profile considering this flow condition only is found adequate. In tight-gas reservoirs, however, the early production period is dominated by the transient flow...

... Abstract Conventional, cross-linked gel, hydraulic fracture treatments face several challenges in naturally fractured, tight gas, hard rock environments. These challenges include the potential for fracture complexity, pre-mature screen-out caused by pressure dependent leak-off...
