Lapindo Embankment Security Monitoring System Based on IoT

Since 2006 Lapindo mudflow caused by natural gas drilling in Sidoarjo. Nowdays the mudflow still can't be stopped, and to prevent it from resident's houses, embankments were built. Eventough the embankments and guardrails has been built but sometimes the mud flowing into resident's houses while its raining or the embankments were subsidence or reep. Severity, the distance between the embankment and the residents' houses is about 500 m. So far, the handling action while embankments ware subsidence is residents report the accidents to related parties, namely PPLS. But the response is too late and take a long time to occur the accident, so the mud has been flow in to resident's houses. because so far it is still completely manual and there is no monitoring system can detect the accident in the embankments. Therefore with monitoring the embankments with vibration and overflow of the lapindo puddle using wirelless sensor network spread over a number of dike-prone points, then its send to smartphone via Blynk. When the accident happend system monitoring aplication will be warning and send message easly via smartphone. So the existence of this monitoring tool can provide a sense of security to the citizens.

Temperature and Pressure Insensitive Spectroscopic Method for Measuring 13CH4 during Oil and Natural Gas Drilling Operations

A novel rugged two-section driving NIR TDLAS scheme was implemented to reduce temperature and pressure sensitivity of methane carbon isotope measurement during oil and natural gas drilling operations. Isotope spectra line groups with same lower energy levels were selected to derive the concentration of 13CH4 and 12CH4. Dynamic pressure linewidth broadening was introduced in the absorbance curve fitting. Various uncontrollable factors such as spectra shift, stretching, and baseline trending were incorporated in the comprehensive multi-peak fitting. The results showed that the sensitivity of isotope ratios to temperature and pressure variation was greatly suppressed. The δ13CH4 uncertainty in the temperature test was 2.8‰ with fitted δ13CH4-T slope of 0.021‰/°C in 25 ± 5°C range. The δ13CH4 uncertainty in the pressure test was 1.4‰ with fitted δ13CH4-P slope of <0.001‰/mbar from 400 to 1000 mbar. The limit standard deviation of long-term test was 0.15‰ (@135 s). The results indicate that our scheme is a promising solution for δ13CH4 measurement during drilling operations due to the enhanced robustness.

Marcellus Shale Gas Development and Farming

We study changes in farming in the Marcellus region associated with unconventional natural gas drilling activity. Due to concerns raised by the popular press, we consider 18 different county-level agricultural variables. While we find no significant changes in the number of farms or land in farms in drilling counties relative to non-drilling counties, there is an increase in median farm sizes, indicating potential consolidation in drilling counties. Despite anecdotal evidence suggesting a transition away from dairy farming to either beef or hay production, we find no support for this at the county level.
