was required because they were all members of the unit sharing in all production from the unit. Because the Ohrt-Heinold No. 1 Well was the only well in the unit, if appellants had prevailed on their claims seeking cancellation of the unit, appellants would have received all royalties from that well, and other unit lessors, including the McAdams and Chilcoats, would be entitled to no royalties on the Unit’s production from the well. Appellees further assert that the evidence showed that the Ohrt-Heinold Well was draining gas from under the McAdams’ and Chilcoats’ lands, entitling them to a share of the production from the well. We conclude that the trial court did not abuse its discretion in allowing joinder of the third-party defendants. See Royal Petroleum Corp., 332 S.W.2d at 316-17 (<HOLDING>); Veal v. Thomason, 138 Tex. 341, 159 S.W.2d
