What changed in Colombia’s petroleum framework?
ANH says the 2003 restructuring created ANH, separated Ecopetrol’s regulatory and operating roles, and introduced a new contract model to attract private investment.
Resource policy
Colombia separated regulation from operations—and private capital entered an older petroleum asset chain.
Official ANH history describes a 2003 restructuring that created the agency, separated Ecopetrol’s regulatory and operating roles, and introduced a new contract model intended to attract private investment. The archive’s earlier 1995 records document Omimex and Sabacol in the former Texas Petroleum or Texaco asset chain.
PRIMARY RECORDSPOLICY CONTEXTCLAIM BOUNDARIES
What is documented?
SEC-filed exhibits and an ANH–Ecopetrol convention identify transactions involving Texas Petroleum Company, Omimex de Colombia and Sabacol over Cocorna, Nare and the Velasquez–Galan pipeline. Buyer-side reports later document a 2006 acquisition by the ONGC/Sinopec-backed Mansarovar structure.
What remains unresolved?
The records do not trace cellular money into Colombia, establish an ISM batchmate role, show the complete seller allocation, or convert ONGC Videsh’s reported $437.5 million acquisition investment into Naresh Vashisht’s personal proceeds.
