how valuable Is MSc online in petroleum Engineering at herriot watt to multinationals

Please I need your candid advice. What's your view about studying online for an Msc degree especially in petroleum Engineering from herriot watt. I have a friend that is working as a banker for close to 3 years, but has a bsc in chemical engineering, who is interested in doing this Msc online. But I discouraged him on the ground that he will not be able to devote quality time in his study epecially for the fact that he is working in a bank, which can be very tedious and also, it will be very difficult for him to assimilate, since he doesn't have a Bsc in petroleum engineering.
I also, told him that most companiess don't recognise Msc online, although he said the msc of herriot watt online is the same as that of full time and that the certificate will not bear online.
Please I want u to advice my friend for me. Thank you.
