Claren Energy Provides Additional Operations Update



Toronto – January 24, 2017 – Claren Energy Corp. (“Claren” or the “Company”) (TSX-V: CEN) is pleased to provide a further wellsite operations update. In order to prepare the Bobocu 310 side-track (“B310-ST1”) for well-testing operations, B310-ST1 has been cased, cemented, and all surface facilities installed at the well-head in preparation for testing.

The MR-8000 drilling rig has been released. A more agile service rig has been mobilized to the site, to facilitate both the logging and additional testing of the well.

The Company plans to not only complete drill stem tests (“DST’s”) on the Lobe G and Corcova sandstone reservoirs, but also test the additional gas sands above Lobe G (Lobes K, J and H) more cost effectively. For risk mitigation purposes Claren will perform cased-holed versus open-hole wireline logging. Cased-hole wireline logging will also provide further insight into selecting the prospective reservoir units to be tested. Well testing operations will commence shortly after the cased-hole logging program has been completed.

“We are pleased that this well has validated our geological model within the Bobocu Gas Field. The incoming service rig is planned to evaluate all selected reservoir units, and will do so in a more cost effective manner. We look forward to completing our testing program and subsequent disclosure of results”, stated Henry Aldorf, Claren’s Chairman and CEO.

Open-hole logging refers to logging operations that are performed on a well before the wellbore has been cased and cemented. In other words, the logging is done through the bare rock sides of the formation. This is the most common type of logging method because the measurements are not obstructed and it's done during or after the well has been drilled.

On the other hand, cased-hole logging involves retrieving logging measurements through the well casing, or the metal piping that is inserted into the well during completion operations. Cased-hole logging is performed more rarely but still provides valuable information about the well.

Cased-hole logging is used to help operators obtain additional information from a well or reservoir that has already been completed. For example, the well may have already started production and a cased-hole log could help determine what has hampered flow. In some cases, the decision must be made to plug and abandon the well or recomplete it, and the cased-hole log will help identify what lies beyond the casing of the well.

Cased-hole logging can be used to evaluate the formation and completion of the well, as well as determine the state of the cement, corrosion and perforation. Both gamma ray and neutron porosity logs can be run through the casing of a well, and better ideas of thermal decay and interval transit time can be achieved through porosity, hydrocarbon saturation and producibility measurements.
