Randy C. Tolman was project coordinator for ExxonMobil's Piceance Development Project located in western Colorado. As a native of the Rocky Mountains, he joined Exxon's Oklahoma City District in 1982 with primary responsibilities for on site supervision of completion operations in the Rockies. In 1985, he joined the start up team for Exxon's LaBarge  Project as first line supervisor. Tolman spent 1988-94 in West Texas working secondary and CO2 flood oil recovery operations. He subsequently returned to Exxon's LaBarge project in 1994 as Sr. Field Supt., and in 1999 began working with Exxon's Upstream Research Company, assisting in development  of the technology he will be presenting. He is listed as the Lead Inventor for 7 of the patents covering Multi Zone Stimulation Technology. In 2001, he transferred to Houston, Texas to work full time on tight gas sand development in ExxonMobil's Production Dept. He retired June 2010 from ExxonMobil and now runs a private consulting service.


Full Description
ExxonMobil has developed novel reservoir stimulation technologies involving dynamic perforating and annular coiled tubing fracturing that enable the rapid delivery of numerous high-quality stimulation treatments within a single cased wellbore. These technologies were developed for the purpose of improving, or enabling, economic hydrocarbon recovery from formations that contain multiple stacked reservoir intervals or require the stimulation of long productive intervals. These technologies do the following:
  • Enable the stimulation of multiple target zones via a single deployment of downhole equipment
  • Enable selective placement of each stimulation treatment so that they may be designed specifically for each individual zone to maximize well productivity
  • Provide positive isolation between zones to ensure each zone is treated per design and previously treated zones are not inadvertently damaged
  • Allow for treatments to be pumped at high flow rates to facilitate efficient and effective stimulation
  • Perform these operations simultaneously on wells to achieve maximum equipment utilization.   This presentation will describe the background leading to the conception and development of these technologies, reveal lessons learned and refinements in their deployment, and disclose information on field implementation and economic impact.

Key Idea: Performing numerous stimulation treatments selectively, rapidly and in a cost-efficient way is essential to the economic viability of exploiting thick and multi-layer low permeability reservoirs.
