Mnazi Bay well 'a gas booster'
Strong results from the latest development well drilled at the Mnazi Bay concession onshore Tanzania have boosted the production potential of the gas field that is due online later this year, according to partner Wentworth Resources.
The MB-4 well struck total net pay of 65 metres in the Upper and Lower Mnazi Bay reservoir sections that tested at respective flow rates of up to 18.8 million and 22.2 million cubic feet per day in the concession, operated by French player Maurel & Prom (M&P).
Wentworth said in a statement the results confirm the field’s “ability to produce over and above the initial 80 million cubic feet per day” after scheduled start-up in the third quarter, adding it could achieve output of up to 130 MMcfd.
The pay zones are “ranked among the best of five wells” drilled at the field to date and the well will now be hooked up to production facilities that are currently being installed at the concession.
Wentworth’s managing director Geoff Bury said the well result “confirms our reservoir model” for the field and “also provides additional flexibility for meeting gas delivery obligations” under a sales agreement with the Tanzania government.
First gas from the field has been delayed by a few months from the earlier scheduled date of July as commissioning of an associated export pipeline from Mtwara to Dar es Salaam pipeline has been stalled.
M&P holds a 42% operating interest in the concession, with Wentworth on 32% and state-owned Tanzania Petroleum Development Corporation on the remaining 20%.
