In Tripura only high-tech AC-VFD rigs can work

Vol 20, PW 8 (12 Jan 17) Exploration & Production

More than a year has passed but ONGC's Tripura workers union has not given up its demand to chairman DK Sarraf that it absolutely needs two US-made heavy duty 1300-hp drilling rigs to meet its targets.

Tusar Majumdar, general secretary of the workers union, confirms to this report he will raise the matter at a meeting with ONGC's Board in the third week of January. Majumdar wrote again to Sarraf on November 17, 2016, more than a year after he sent a similar letter on September 26, 2015, stressing the asset desperately needs two heavy duty rigs.

Majumdar writes that even if Tripura buys just one AC-VFD rig in addition to its current fleet of three ONGC-owned rigs it can drill 15-18 wells a year exceeding its target to drill 14-15 wells. He cannot understand why top management has instead ignored the workers union and chosen to hire three rigs from Deep Industries, John Energy and Quippo, with a tender out to hire yet another, taking the total number of hired rigs at the asset to four.

"Based on previous results of hired rigs in Tripura asset," writes Majumdar, "we are dismayed that our performance would be degraded (sic)." As a hilly state, Majumdar believes two hi-tech AC-VFD rigs that can drill in HP/HT conditions would be far more useful. He also repeats a demand for two 200-tonne workover rigs for well testing.
