The largest part of Mr. Borrego’s practice consists of drafting and negotiating exploration and development agreements, as used in the onshore domestic oil and gas exploration industry, the offshore industry, and the international oil and gas industry. Because of the nature of the industry, it is difficult to characterize all types of agreements, a partial list would include: joint venture agreements, farmouts, farmins, participation agreements, bottom-hole, dry-hole and acreage contribution letters, joint operating agreements, oil and gas leases, production sharing contracts, concession agreements, drilling contracts, platform use contracts, group shoot agreements and bidding agreements, as well as licensing agreements for the use of seismic or other data. Frequently, these agreements require the drafting and negotiation of ancillary agreements to allow the parties to conduct the operations which are contemplated by the original agreements. By necessity, Mr. Borrego is involved in the drafting and negotiating of accounting procedures, easements, assignments, royalty and mineral deeds, bills of sale, compressor site agreements, master service agreements, construction contracts, time charter agreements, bareboat and helicopter charter agreements.

Because so much of the legal framework of the oil and gas industry was created in the onshore regions of Texas, Oklahoma and Louisiana, many of those instruments, and certainly the concepts, have been used as templates or models in the offshore and international oil and gas industry as well. A careful student of the antecedents of the joint operating agreement as used in the United States onshore industry will see that many of its aspects are to be found in the operating agreements which are used by international companies doing business throughout the world, as well as national oil companies seeking to do business with multi-nationals.
