Natural gas developer and producer Sacgasco is set to begin testing at the Dempsey 1-15 well in the Sacramento Basin in California, US, within the next two to three weeks.
The development follows the company's completion of the drilling phase and a 5.5in liner has been cemented to protect all potential reservoirs underneath the existing nine 5in/8in casing.

Data from Wireline log indicated the presence of gas saturated sands within multiple zones.
The testing programme will be stopped upon establishment of sufficient flow for production at commercial rates.
Sacgasco managing director Gary Jeffery said: “The drilling of the Dempsey well supports our views on the exciting gas potential of the under-explored strata underlying the prolific Sacramento Gas Basin.
“The wireline logs have confirmed the zones of potential future production and we have now safely cemented those zones behind a steel liner.”

By GlobalDataAccording to the company, the strata have not been significantly explored in the Sacramento Basin, and as a result, there are no nearby analogue producing reservoirs.
The company therefore intends to carry out flow testing to ascertain whether the gas sands have a combination of porosity, permeability and access to volumes of reservoir rocks of sufficient quality to flow gas.
Once the flow testing is ceased, the well is expected to be placed into production.
Furthermore, the company noted that some months of flow testing and production, along with integration of data from the Dempsey 1-15 well with the 3D seismic data, is required to have a more complete understanding of the potential gas available for future production.
