* Standalone Q2 profit 82.65 bln rupees; forecast 88.05 bln
* Jio Q2 revenues 61.47 bln rupees, loss of 2.71 bln
* To continue pumping about $1 bln per quarter into Jio (Adds analyst comment, exec comment on debt)
MUMBAI, Oct 13 (Reuters) - Reliance Industries Ltd's telecoms arm Jio will turn profitable "shortly," the Indian conglomerate said on Friday, while adding it would continue to pump around $1 billion into the venture for each of the next few quarters.
Jio launched late last year with free voice and cut-price data, sparking a price war in India's cut-throat telecoms sector which has driven down margins and forced consolidation.
Oil-to-retail giant Reliance, controlled by India's richest man Mukesh Ambani, suggested there were signs its costly gamble was paying off. Jio racked up 61.47 billion rupees ($947 million) of revenues in the three months to Sept. 30, though made a loss of 2.71 billion rupees.
"I can only see it (net income) turning positive very shortly," joint Reliance finance chief V Srikanth said, as the group disclosed Jio's bottom line for the first time.
Jio's net debt stood at 490 billion rupees, Srikanth said, adding that parent Reliance's debt will peak in the quarter to December or the next quarter, after which it will begin sliding, suggesting robust growth for the conglomerate.
Reliance will continue to spend around 70 billion rupees a quarter on Jio for the next few quarters, Anshuman Thakur, Reliance Jio's head of strategy said. Reliance has poured more than $30 billion into Jio so far.
To woo customers to Jio's network, Reliance in July launched a $23 phone that blurs the lines between a smartphone and a basic feature phone.
Earlier this month, it also launched a guaranteed buyback offer for Jio customers buying Apple Inc's latest iPhones.
The wireless carrier reported an average revenue per user (ARPU) of 156.4 rupees. The country's top wireless carrier Bharti Airtel's ARPU was 154 rupees, while smaller rival Idea Cellular's APRU stood at 141 rupees in the April-June quarter. Jio's subscriber base swelled to nearly 139 million at the end of September.
"It will not be a surprise if they break-even or turn a profit in the last quarter of this financial year," said Jagannadham Thunuguntla, head of fundamental research at domestic brokerage Karvy.
"Now what investors are thinking is how they will scale up their ARPU from 156 rupees to, say, 180 rupees."
On a standalone basis, including just its refining, petrochemicals and oil and gas exploration businesses, Reliance posted a 7.3 percent rise in its second-quarter profit, helped by higher margins from its refining and petrochemicals.
Net profit was 82.65 billion rupees in the quarter to Sept. 30, its highest ever. But that was below analysts' average estimate of 88.05 billion rupees, Thomson Reuters data showed.
The refining and petrochemicals businesses delivered an 11.5 percent rise in quarterly revenue from operations to 717.61 billion rupees.
Gross refining margin (GRM), the profit earned on each barrel of crude processed, was $12.0 for the quarter, a nine-year high, but shrunk to $3.7 per barrel against the benchmark Singapore complex margins due to a falling price difference between light and heavy crude oil grades, Srikanth said.
Last quarter, the company outperformed Singapore's benchmark GRM by around $5 per barrel.
On a consolidated basis, which also includes Reliance Industries' U.S. shale gas, retail and other operations, profit came in at 81.09 billion rupees, the company said.
Ahead of the results, shares in Reliance hit a record high of 890.7 rupees, rising as much as 2.1 percent.
