1 Jingbian Gasfield is a large gas field of low permeability and low abundance, encountering difficulty in its development due to special geological features.

2 Jingbian Gasfield is a low-permeability gas reservoir with strong heterogeneity and it is difficult to verify its productivity.

3 The Jingbian Gasfield is located in the central of the Ordos Basin.

4 The Salah gasfield project in Algeria, run by BP, strips CO2 from local natural gas and injects it back into the ground.

5 In recent years, South Sichuan Gasfield has made a great success of secondary exploration in the Lower Triassic Jialingjiang Formation in the old zones.

6 In addition, the activities of firms moving into the area in response to gasfield opportunities are also being monitored.

7 The weathering crust of Majiagou Formation in Ordovician of Changqing Gasfield in Ordos Basin is the major pay zone with the evaporated marginal sea facies.

8 If using the node system analysis method to draw up the program of production and gathering system in each gasfield, it is favorable to optimize production and predict performance of gasfield.

9 A comprehensive control system imported, combining SCADA system and DCS system, has operated very well during the development of gasfield in surface auxiliary facility of Changqing gasfield.

10 Later in 2005 aChinese naval squadron appeared near the Chunxiao gasfield ( known in Japaneseas Shirakaba ).

11 As one of the main gas reservoirs in oil and gasfield of southwest Sichuan Basin, Shaximiao reservoir of Xinchang gasfield is now in the production decline stage.

12 XX production zone is the key production block in Jingbian Gasfield, which dominates the production of the whole gas field to certain extent.

13 Taking a successful experience in a drilled well as an example, this study finally concluded that the refined acid system and acid fracturing technology adapt well to the Puguang Gasfield.

14 The research work in the field of acidizing and fracturing have been done for about 30 years by RINGT, PetroChina Southwest Oil and Gasfield Company.
