D -- NOTICE OF INTENDED SOLE SOURCE AWARD SOL 3989 POC Sandra McLaughlin 703-787-1361 E-MAIL: Use this link to contact the Contracting Officer, Sandra.McLaughlin@MMS.gov. [See Numbered Note 22.] This is NOT a request for competitive proposals. This constitutes notice that the Minerals Management Service (MMS) intends to non-competitively award a contract to Daniel H. Wagner Associates, to correct source code errors and errors in the implementation of statistical and mathematical approaches, in a proprietary computer model known as GRASP/PETRIMES. The errors were identified by Wagner in a previous, competitively procured study of the model. The model is to be used by the MMS to support its requirement to develop resource estimates for geological plays for oil and gas hydrocarbon components. In the performance of the previous contract, Wagner & Associates demonstrated both superior fluency in FORTRAN (the language the model is written in) and the ability to comprehend the model's statistical and mathematical complexity and express it in simpler terminology. Because of Wagner's prior experience with this model, no other contractor would have the same ability to performthis project in an efficient manner, without substantial increases in cost and schedule due to learning curve and other factors.
