Nicollet, who has come through qualifying schools last two years but failed to keep her card, is coming back from a series of injuries this year.
Another Indian in the qualifiers, Smriti Mehra shot 74 after a first round 76 to be tied 75th.
England's Georgia Hall has extended her lead to four strokes after the second. The 18-year-old from Bournemouth fired a flawless four under par 68 at Al Maaden Golf Course on day two here.
Hall made the most of the calm and sunny weather conditions with 11 straight pars before picking up four birdies on the back nine. She recorded her first birdie on the 12th and then added three in a row from the 15th.
Play continues over both the Al Maaden and Samanah courses for the next two rounds before a cut to the leading 60 players and ties. The top 30 players and those tied will earn LET Membership in Category 8a for 2015 after the final round at Samanah on Sunday.
