Dragon's offshore LAM 22-102 well comes onstream

Feb 20, 2002 01:00 AM

Ireland's Dragon Oil announced that its LAM 22-102 well in Turkmenistan's offshore zone had started production. Dragon said on February 11 the well was drilled to a depth of 4,152 meters using sliding-sleeve technology that allowed testing and production from four different oil-bearing intervals. It also said that a 10-inch flow pipeline had been recently commissioned and would be used to move the well's output.
It said all four oil-bearing intervals had been tested and that three were currently producing crude simultaneously at an aggregate rate of approximately 3,200 bpd, with flowing well-head pressure at 1,300 psi, while gas had been measured at 2 mm cfpd.

Dragon said it had collected a significant amount of data from the LAM 22-102 well, and as a result the drilling rig has been skidded back to the LAM 22-101 well in order to carry out a re-completion program. LAM 22-101 was the first well to be drilled in the Cheleken block since the late 1980s and the first in the block to make use ofWestern drilling technology. Drilling was financed through a $ 60 mm loan from the European Bank for Reconstruction and Development (EBRD) and a $ 30 mm credit facility from ANZ Grindlays Bank of Dubai.
LAM 22-101 was also the first new well drilled by Dragon in the Cheleken field. It began operating from one interval yielding 2,000 bpd of condensate and also produced large volumes of gas at high pressures. The company said that output from LAM 22-101 was going into a 4-inch inter-field pipeline and that the high pressure meant the well had to be constrained to comply with the safe operating pressure of the 4-inch line.

It also said that further constraints were caused by the formation of gas hydrates in conjunction with natural production decline. This, it said, resulted in production from LAM 22-101 falling to around 1,200 bpd of condensate before it was shut in during the testing of the LAM 22-102 well.
LAM 22-101 is to be re-completed in order to isolate the gas condensate zones behind sliding sleeves, providing future access, it said. The well would be completed over a shallower zone and run into the 10-inch pipeline connected with LAM 22-102, data from which is to be used to improve the performance of LAM 22-101, it said.

Dragon Oil Turkmenistan Ltd (DOTL), a wholly-owned subsidiary of Dragon Oil, is the operator and 100 % equity shareholder in the Cheleken contract area production-sharing agreement (PSA), which covers the offshore LAM and Zhdanov fields in the Caspian Sea. Dragon signed a 25-year PSA for the Cheleken joint venture Block-2 (Cheleken) in November of 1999.
The PSA contains the LAM and Zhadanov fields and calls for new exploration and refurbishment of the fields as well as for Dragon to increase the capacity of both onshore and offshore facilities. Turkmenistani authorities issued a drilling license in May of 2000.

Dubai-based Emirates National Oil Company (ENOC) owns 69.4 % of Dragon Oil. Dragon's rate of production at Cheleken is around 7,000 bpd, coming from 18 pre-existing wells at the block; it expects production from the field to increase 10-fold in coming years through the drilling of new wells.
Dragon estimates that the LAM and Zhdanov fields' reserves amount to approximately 600 mm barrels of crude oil and 2.3 tcf of natural gas. Meanwhile, Malaysia's state-owned oil company Petronas has announced plans to drill two exploration wells in Turkmenistan's offshore Block 1 during 2002 with the intension of starting production in 2006.
