Taribani Field Unit – Dino #2 Well Operations Gallery, August – May 2006

August 2005: Frontera announces the award of a drilling contract to Turkish Petroleum International Company LTD (TPIC), a subsidiary of Turkish Petroleum Corporation. Under the terms of the contract, TPIC will provide the F-200 rig and certain associated services in support of Frontera’s plans to drill lateral or horizontal wells at the Taribani Field Unit. Under the agreement, Frontera is committed to utilizing the TPIC rig to drill three wells, with an option to drill up to six additional wells. The F-200 rig is pictured below in TPIC’s staging yard in Turkey as it awaits mobilization to Georgia.

November 2005: Operations commenced at the Dino #2 well on November 2nd , the first well designated for horizontal drilling operations at the Taribani Field. The TuHa ZJ-30 rig, below right, is conducting the first phase of operations that included reentering the well with drill pipe to clean and wash it free of debris; logging and pressure testing of the existing well bore to confirm casing integrity; and the setting of a bottom-hole cement plug to ensure a sound well-bore from which sidetrack drilling operations would next commence.

November 2005: On November 15th, the first phase of operations was successfully concluded and the TuHa ZJ-30 was demobilized to another well location at Taribani Field to continue preparation operations for subsequent wells that have been designated for horizontal drilling operations.

December 2005/January 2006: TIPIC F-200 rig is mobilized to its location in the Taribani field from southeastern Turkey via truck convoy. Due to harsh winter conditions along portions of the mobilization route (below, upper left) delays were experienced in moving the convoy of approximately 100 trucks.

Drilling operations at the Taribani Field

February 2006:  As drilling continues at the Dino#2 location (black box photo, below),  the drilling crew executes drilling operations from the rig floor on the F-200 rig (red box photo, below).  Another portion of the rig-site crew manages and maintains the shale-shaker units that serve to separate rock cuttings that are brought up from the bottom of the hole as mud is circulated in and out of the well bore to keep it clean (green box photo, below).  Rock cutting samples are then taken to the mud logging unit where they are analyzed by a well site geologist as drilling progress is mapped in real time against drilling plans (blue box photo, below).

March-April 2006: Coring operations underway. Pictured below is the ‘core barrel’ being raised from the hole after successfully capturing formation rock samples. Blue box inset photo: On the rig floor Baker Hughes engineers inspect the bit that is situated on the end of the core-barrel that drilled and captured rock samples from Zone 9. Approximately ninety meters of core samples were taken from Zones 9 and 15. The rock samples taken will provide calibration for existing field mapping, assist in the study of fracture systems and provide new insights to reservoir characterization.

March-April 2006: After core samples are taken, Baker Hughes logging crews move in and conduct further well-bore imaging and analysis over key reservoir sections with specialized tools. Reggie Spiller, Frontera’s Executive Vice President, Exploration-Production, with Baker Hughes’ logging team (red box) and with logging engineer on the rig floor as a logging tool is lowered into the drilled hole (blue box). Data is transmitted from this and other similar tools to the computers in the logging unit (green box) where engineers review and record reservoir data (black box).

March-April 2006:  In tandem with coring and logging runs, Frontera’s integrated geoscience and engineering team visits Zone 14 and 15 outcrops once again in order to better calibrate and interpret the new cores and logs.  Below, far left, Ismail Abalioglu, Frontera’s Chief Wellsite Geologist for the Dino#2 drilling operation, with colleagues conducting outcrop studies of objective zones that can be seen in the background.  Below, right, Reggie and Ismail work with our technical team to further field fracture analysis.

April-May 2006: Once coring and logging operations are complete, drilling resumes in order to finish the drilling of the Dino #2 well and complete it in Zones 14 and 15. In the photo below, rig-floor crews assemble joints of drill-pipe as the well is drilled to a total measured depth of 3,040 meters.
Drilling operations underway

April-May 2006: As drilling operations progress through the target zones, high pressure oil and gas reservoirs are encountered while drilling through Zones 14 and 15. This resulted in the need to flow oil and gas while drilling from time to time. (Click on the red box and green box to view short videos of oil flow and flaring operations.) Pictured in the blue box below, Paolo Pratelli, Frontera’s General Manager-Operations, leads the drilling effort through challenging high-pressure formations. Mike Pilson, Frontera’s General Manager-Exploration, together with Chief Wellsite Geologist, Ismail Abalioglu, provide on-site integrated geoscience direction to the drilling operation (below, yellow box). Click here to watch videos.

May 2006: With drilling operations complete, a Xmas tree is installed on the completed Dino #2 well, below left. Throughout June and July, the well will be tested and flowed into existing production facilities at the Taribani Field that are situated in close proximity to the well, below right. From this testing program, optimal production rates will be determined. In the meantime, the drilling rig will be moved to Taribani Field well #23 where it begin drilling during the second half of May.
