Greenfields Petroleum Corporation ("Greenfields" or the "Company") (TSX VENTURE:GNF), an independent exploration and production company with assets in Azerbaijan, announces financial results for the year ended December 31, 2011.

Annual and Fourth quarter 2011 operating highlights

• The Corporation's entitlement sales volumes from production for its net interest in the Bahar ERDPSA averaged 360 bbl/d and 4,276 mcf/d or 1,072 boe/d in the quarter and 397 bbl/d and 4,121 mcf/d or 1,084 boe/d for the year.

• Through its interest in Bahar Energy, the Corporation realized average oil and gas prices of $104.71 per barrel and $3.96 per mcf in the quarter and $103.53 per barrel and $3.96 per mcf for the year.

• 4 limited recompletions undertaken in 2011 of which 3 were successful and added initial 375 bbl/d of new production.

Activity highlights and plans

• Weather in the south Caspian area during the winter of 2011-2012 was, according to local reports, the worst in more than 100 years. Snow, ice and wind caused temporary production declines. Workover activity, field maintenance and seismic data acquisition programs were suspended due to the difficult weather conditions.

• During the next twelve months Bahar Energy will continue work related to construction and upgrades of facilities. Areas of focus include platform design and construction, oil and gas processing facility upgrades, pipeline replacement, water disposal, electric power line installation, support infrastructure and safety monitoring. As of this date, the topsides on Platform 2 and 196 have been removed. Pile caps have been fabricated and delivered to site. Once they are installed, these platforms will be ready for rig mobilization. A design concept for new platform construction was completed and is pending soil bore analysis for pile and jacket design. Two 14,600 bbl oil storage tanks were contracted for construction. One is nearing completion and the other is about 60% complete.

• During 2012 Bahar Energy expects to drill at least 6 wells in the Gum Deniz field and to recomplete approximately 16 wells in both Gum Deniz and Bahar fields. The drilling program will continue in 2013 and beyond, and includes a total of 83 new wells in the Gum Deniz field and 7 in the Bahar field. Total planned recompletions include 29 in the Gum Deniz field and 40 in the Bahar field.

• Workover and rehabilitation operations continued through 2011. A total of 12 maintenance jobs and 4 workovers were performed using the older Soviet-era rigs contracted from SOCAR. This program was successful in performing basic well services, including tubing and gas lift repairs. Success in workovers and recompletions was slowed due to the limitations of the Soviet-era workover rigs. The rigs are limited in their capabilities to pull tubing, clean out sand and perform wireline work and are unable to rotate pipe, perform cementing work or do jobs fishing for downhole material. Only 4 limited workovers were undertaken with 3 of 4 being successful initially adding 375 bbl/d of new production.

• Two new Western-style workover rigs arrived in Poti, Georgia on April 6, 2012 and their arrival in Baku is expected in late April and early May. These rigs are designed for the operational requirements of the Gum Deniz and Bahar fields and are under three-year contracts. After arrival, the rigs will undergo a thorough commissioning process, then be mobilized and installed on offshore platforms using a heavy-lift crane barge. The rigs will initially operate from Platform 2 in the Gum Deniz oil field and Platform 196 in the Bahar gas field. To accommodate drilling operations, significant modifications were made to these platforms. Except for pile caps, this work has been completed. Pile caps are expected to be installed prior to the rig mobilizations. Drilling operations are expected to start in June.
  
  The rig assigned to the Bahar field will work in recompleting gas wells that have, in most cases, been shut in due to operational difficulties. These wells have significant potential in untested zones behind pipe productive zones. Five recompletions are expected to be done in 2012.
  
  The modern rig assigned to the Gum Deniz field will be engaged in drilling development wells in the under-developed northern area of the Gum Deniz field. It is being upgraded for drilling by adding a topdrive, larger mud tanks and 1300 horsepower ("HP") drilling mud pumps. At least four wells are expected to be drilled in 2012. The field development plans include a total of 23 wells in north Gum Deniz field, which will be drilled from existing platforms, and a total of 60 wells which will be drilled in the south Gum Deniz field on new platforms presently in the design stage.

• Two seismic data acquisition programs, the 2D in the Gum Deniz field and the 3D in the Bahar-2 exploration area, are expected to be completed in 2012. After delays related to vessel suitability and weather, the 140-km 2D project was completed in April 2012. The data quality appears good and is being processed and interpreted.
  
  The 3D project started in June 2011 and after acquiring 45 km² of 3D data, was delayed further when the work was suspended due to bad weather. Acquisition is expected to restart in May, when an additional 43 km² of 3D will be shot. After acquisition, processing and interpretation will be conducted. If the interpretation confirms an attractive exploration prospect in the Bahar-2 exploration area, Bahar Energy will develop an appropriate drilling strategy to evaluate the prospect. Drilling could occur in late 2013 or early 2014 in the Bahar-2 area.
