A system and method of detecting gas leakage along an underground pipeline system accurately determines the presence of a gas leak while minimizing cost and preserving energy. The system includes at least one underground pipeline with a plurality of stack vents, a plurality of sensor units, and at least one remote server. Each sensor unit is mounted within a stack vent. The method begins by tracking a current time with each sensor unit. A gas-concentration reading with at least one specific unit is captured and then communicated along with a sensor location and a sensor identification to the remote server and recorded with the remote server. The tracking, capturing, and communicating of the gas-concentration reading is repeated so that actual gas-concentration data is compiled and compared to a baseline gas-concentration data or a defined gas-concentration threshold. A leak notification for a gas leak is then sent with the remote server.

A device including a housing having an access opening, a swing arm mounted to the housing and configured to be selectively pivoted toward and away from the access opening, and a closure captured by the swing arm. The closure can be configured to be selectively moved in a substantially vertical motion relative to the swing arm between a retracted position and an inserted position at least partially in the access opening and can have locking features for cooperating with engagement features in the device to move the closure into a closed and sealed configuration.

Embodiments of the disclosure can include systems, methods, and devices for determining saturation pressure of an uncontaminated fluid. A technique facilitates fluid analysis in situ at a downhole location. Downhole saturation pressure measurements and downhole OBM filtrate contamination of a contaminated fluid may be obtained and a relationship may be determined between the saturation pressure measurements and OBM filtrate contamination. The relationship may be extrapolated to zero OBM filtrate contamination to determine the saturation pressure of the uncontaminated fluid. According to an embodiment, a sample of oil is obtained at the downhole location from oil in a reservoir. A downhole sampling system is used to determine whether a sample has contamination and other selected characteristics of the sample. The data obtained may be processed to provide a formation volume factor of the oil.
