Drilling of three wells in the Gulf of Thailand to go ahead

Tap Oil Limited has provided updated information in relation to the Manora 2020 development drilling campaign now scheduled to commence on or around 15 May 2020.

After comprehensive technical and commercial assessment of a number of portfolio opportunities the Operator, Mubadala Petroleum LLC, and Tap have agreed to drill, complete and put on production three wells in the Manora 2020 development drilling campaign.

These drilling operations represent cost-effective opportunities for Tap to develop undeveloped reserves with a total estimated cost of US$3.4 million (net to Tap) for the entire three well program, based on the Operator’s AFE estimates.

In addition, while the rig is on location at Manora in the Gulf of Thailand, the Joint Venture parties have decided to cost-effectively workover the MN-15 well to replace an electric submersible pump and workover the MNA-7 well to add water disposal capacity.

Total cost of the two workovers, net to Tap is US$0.64 million, which will bring the expected total cost of the development drilling and workover program to US$4.04 million net to Tap.

 

The three well development drilling program comprises:

 

The MNA-25 Development Well

The primary objective of the MNA-25 deviated development well is to produce oil in the 600 series reservoirs of the Manora Central Fault block.

The well is expected to be drilled close to the existing MNA-01 well, targeting 610, 620 and 650 sands in an updip location.

Tap outlines that MNA-01 is still producing at 680 barrels of oil per day (bopd) gross with 84 per cent water cut from the 650 sand.

The well is expected to be drilled to a maximum measured depth of 2,400 metres and completed with a multi-zone completion. Gross estimated drilled and completed cost is US$4.12 million US$1.24 million net to Tap).

The Operator’s estimated initial production rate is 1,100 bopd.

 

The MNA-26 Development Well

The primary objective of the MNA-26 horizontal development well, also located in the Manora Eastern Fault Block, is to produce potentially undrained oil in the 370-10 reservoir that was first developed by the 2019 MNA-24 horizontal well.

The sand lobe being targeted is interpreted to be separate from the productive sand in the MNA-24 well, which is still producing at approximately 900 bopd with an 18 per cent water cut; having produced 230 MSTB gross of oil since being put into production in July 2019.

It is expected that the well will include an approximate 400m horizontal section in the upper 370-10 reservoir completed with a sand screen.

MNA-26 is also slated to be drilled to a maximum measured depth of 2,225 metres at a gross estimated drilled and completed cost of US$3.64 million (US$1.09 million net to Tap).

The Operator’s estimated initial production rate is 1,100 bopd.

 

The MNA-27 Development Well

This new deviated well from a new platform slot effectively twins the MNA-22 well drilled in 2019 that was unable to be put into production at the time due to poor cement bond behind the production casing.

Tap states that petrophysical interpretation of MNA-22 well logs outlined a total oil net pay of 56.5m in the 490 and 500 series sands.

The MNA-27 well will target these well-developed sands and provide an additional reservoir drainage point in the highly productive Eastern Fault Block of the Manora Oil Field.

It is forecast that the well will be drilled to a maximum measured depth of 2,011 metres and completed with a multi-zone completion.

Currently, gross estimated drilled and completed cost is US$3.61 million (US$1.08 million net to Tap).

The Operator’s estimated initial production rate is 1,400 bopd.

 

MNA-15 Workover

The electric submersible pump (ESP) on the MNA-15 well failed in February 2019 when the well was producing at 487 bopd gross from the 650 reservoir in the Eastern Fault Block.

According to Tap, the workover is planned to replace the ESP and bring the well back into production.

The Operator expects the well to produce at an initial rate of 300 bopd.

Gross estimated workover cost is estimated at US$0.9 million (US$0.27 million net to Tap).

 

MNA-07 Workover

The MNA-07 well was shut-in in November 2019, while producing uneconomically at a very high water cut.

The well began production in January 2015 and has produced a total of 0.34 million barrels of oil gross, from multiple 600 and 400 series sand zones in Manora’s Eastern Fault Block.

It is anticipated that the well will be completed as a water disposal well in shallow reservoirs and will provide additional water disposal capacity to help optimise Manora production and ultimate oil recovery.

Gross estimated workover cost is estimated at US$1.2 million (US$0.36 million net to Tap).
