No cuts are to be extracted if the volume of material in the State set is less than 10'cc. Even though the .above intervals may overlap intervals within which thin sections are currently on file in the State collection, no thin sections will be'prepared that duplicate the specific footages coverud by existing slides. CITCO will provide the State with a list of the specific sample and core footages sampled.. CITCO shall assume all costs entailed and will provide the Alaska Oil and Gas.~ Conservation Commission with a complete set of all thin sections and return all remaining sam91e and core residues. No sample or core material is to be retained by CITCO. Ail thin sections prepared from these cuts are to be received by the Commission no later than June 1, 1980. It is'mutually understood that the State's well sample library is public property'and that granting CITCO permission.to extract portions of the materials from this library for the purpose of.preparing thin sections is in the public interest.. We are pleased to work with you in this mutually beneficial endeavor and look forWard to your company's continued exercise of care and good judgement in the handling of this well material, as evidenced in the sample processing arrangements CITCOhas undertaken with the State in the past'.

Approximately 100' of 18" ID casing (cemented to surface). 2. Approximately 1500' of 13-3/8'~ OD surface casing (cemented with 500 sacks). 3. Should it become desirable to set intermediate casing, 8500' of 9-5/8" casing will be available. 4. Should production casing be required, an adequate amount of 5-1/2" is on hand for use. This is an exploratory well to an approximate depth of 8500' and there is insufficient information to predict the depths of objective pay zones; therefore~ the setting of intermediate casing is subject to depth and hole conditions.
