birch 3 flow rates, page-7

From ann. 28th Aug

"The Company has successfully drilled its third well at its Texas Birch project to a total measured depth (MD) of
13,213 ft including a 4000 foot horizontal leg into the Austin Chalk formation. This makes Birch #3 the Company’s deepest ever well. "

For my money it sounds horizontal, but what does it mean for flow?
