General Assembly in Klaipeda, 2.-5. April 2017
 

DESTRESS will held the next General Assembly with support from our Lithuanian partner GTL in Klaipeda. This event will include DESTRESS-internal meetings and a joint workshop with the partner project SURE.
We will start with the opening dinner on the 2nd of April and follow with different sessions and excursions to the GEOTERMA plant within the next days.
As there might be some additional offers at the plant with regard to our Site Access Programme between 6th and 7th of April, please refrain from planning your journey until we provide you with travelling instructions, meeting locations and the agenda in the next weeks.

First Efforts to Address Challenges in Klaipeda Geothermal Site (WP4)

      

"How about a quick swim in our pool?" This question could come up when visiting the only running geothermal site in Lithuania. At the western coast of the Baltic state warm salty water is pumped from rocks 1000 m beneath the city of Klaipeda. Sigitas Petrauskas, Robertas Valickas and Antanas Petraitis from Geoterma, the local operator, are especially proud of the recently received certificate, which approves that the water is also clean and eligible for spa purposes. Therefore, guests at Geoterma are invited to enjoy the water of the in-house pool.
Although the team is happy about the strong discharge from the reservoir, at the same time they worry about low recharge into the underground: Running geothermal fluids in a subsurface loop is a main requirement for sustainable use of geothermal energy. Therefore, produced fluid has to be injected back into the reservoir formation. However, geothermal fields often face problems during injection, as the Klaipeda geothermal demonstration site does. Several treatments on site did not bring expected increase of injection rates. Reasons can be manifold and will be investigated with interdisciplinary methods within DESTRESS.
In March and July 2016 geochemists, reservoir engineers and rock mechanic experts from GFZ Potsdam visited the site to sample fluids, filter residual and core pieces for analysis in the laboratory. Discussions between local and visiting experts revealed interesting details, which will presumably help to solve the challenges at Klaipeda Geothermal Power Plant.
Spare time was spent together in the city, which has a nicely renovated old town with cobbled streets and restaurants along the Danes river. Klaipeda is located vis-à-vis the Curonian Spit with long white beaches facing the Baltic Sea to the west. The predominant sunny weather and the kindness of local people are understood as happy omen of work package 4!
