Title: Channel estimation in mud pulse telemetry
Inventor: WENBING DANG
IPC: G01V11/00
Filed: 2015-07-24
Abstract: Systems, methods, and computer-readable media for channel estimation in mud pulse telemetry based on a preamble waveform. A system located at a first location of a wellbore can receive, from a second device located at a second location of the wellbore, a signal including a Golay preamble waveform and data symbols. The Golay preamble waveform can be based on Golay complementary codes. Based on a measurement associated with the signal, the system can then detect the Golay preamble waveform in the signal. Next, the system can estimate a characteristic of a communication channel between the first location and the second location based on the detected Golay preamble waveform.

Title: Improved pipe liner and associated methods
Inventor: STEPHEN BARNES
IPC: F16L58/02
Filed: 2019-10-30
Abstract: A pipe liner, a method of manufacturing the pipe liner and a method of lining a host pipe with such a pipe liner. The pipe liner comprises a barrier layer 311, which prevents permeation through the liner, surrounding an inner polymer pipe and optionally covered by an outer polymer pipe. The inner polymer pipe is porous which permits free movement of gas 307 between the internal bore 302 of a lined pipe 301 and the barrier layer, so as to prevent accumulation of gases anywhere in the lined pipe, while ensuring that gases do not permeate to, and damage, the host pipe. The liner can be inserted using roll down, or any other suitable close-fit lining techniques. without compromising the effectiveness of the barrier layer. The invention relates to the problem of gas permeation through a polymer liner in hydrocarbon service which can result in corrosion of the host. It also relates to the problem of gases accumulating in an annulus between or within the liner and the host pipe and expanding during operational de-pressurisation of the pipeline, causing collapse of the liner.
