Heat oil in a large nonstick skillet over medium-high heat. Sprinkle sea scallops with salt and pepper. Add scallops to pan, and sauté 2 minutes on each side. Remove scallops from pan, and keep warm.
Melt butter in pan. Add shallots and garlic; sauté 30 seconds. Add wine and juice; cook 1 minute. Return scallops to pan; toss to coat. Remove from heat; sprinkle with parsley. Serve with lemon wedges, if desired.
