Abstract: An evaluation method for different types of pore evolution in shale is related, which is applied to the field of unconventional oil and gas research. As the shale depth or maturity increases, different types of pores (including intergranular pores, intragranular pores, organic pores and fractures) developed in shale are constantly changing, which is important for shale oil and gas accumulation. The present invention starts from the high-resolution scanning electron micrography of shale, and respectively extracts the areal porosity of different types of pores based on the division criteria of different types of pores and pore identification in the established shale, and combines the low-temperature N2, CO2 adsorption experiments and the high-pressure mercury intrusion experiments to obtain the total pore volume and establish the evolution chart of different types of pores. The proposed method has an important application value for the exploration of unconventional shale oil and gas resources.

Abstract: Disclosed is a method performed by a communication device (120) for enhancing wireless communication with a network node (110) of a wireless communication network (100). The communication device (120) has received, from the network node, a first timing advance, TA, value at a first time point when in active state, and the communication device has thereafter switched to inactive state. The method comprises switching from inactive to active state, after obtaining an indication of data transfer, determining whether the first TA value is still valid, employing the first TA value for sending data to the network node when the first TA value is determined to be valid, and employing an updated TA value for sending data to the network node when the first TA value is determined not to be valid. By determining that the first TA value is still valid and in these cases reusing the first TA value, communication resources that would otherwise have been used for updating the TA value can be spared.

Abstract: An apparatus and a method for monitoring the relative relationship between the wafer and the chuck is provided, especially for monitoring whether the wafer is sticky on the chuck when the wafer is de-chucked. The lift pins may be extended outside the chuck to separate the wafer and the chuck when the wafer is de-chucked. By detecting the capacitance between the de-chucked wafer and the chuck, especially by comparing the detected capacitance with the capacitance that the wafer is held by the chuck, one may determine whether the wafer is sticky on the chuck, or even whether the wafer is properly supported by the lift pins. Accordingly, an early alarm may be issued if the wafer is sticky or improperly removed. Besides, by controlling a switch electrically connected to a lift pin that contacted the wafer, the charges at the wafer may be eliminated.
