What happens to ITM spreads on Crude oil in MCX close to expiry

Hi,

I have an open spread of 7300 CE (buy)/7350 CE (sell) on Crude oil MCX expiring this month (17th March).

The contract value of 1 lot Crude oil futures is approximately 7500 * 100 = 750000 Rs.
Since the quantity is the same for buy and sell legs, do I need additional margin if I hold till expiry? Will there be any physical delivery obligation?

Thanks.
