Wednesday Afternoon Reading – Microhole CT Niobrara Tests – WOW
Posted by zmann on January 3, 2007
From the EIA 2 weeks ago in their weekly gas comments:
Microhole Drilling Technology: A specially designed new hybrid microhole coiled tubing rig recently completed the drilling of 25 test wells targeted towards the Niobrara formation in Kansas and Colorado, utilizing technology that could have a significant impact on natural gas and oil drilling. The coiled tubing rig passed a series of field tests and delivered cost savings of 25 to 35 percent per well drilled compared with conventional drilling equipment. Furthermore, as a result of these tests, up to 1 Tcf of shallow natural gas that had previously been bypassed by conventional drilling has now been made economically recoverable. Coiled tubing rigs are generally used to service or stimulate production in existing oil and natural gas wells where necessary. However, operators have recently started using these rigs to drill exploratory and development wells, a practice previously limited mostly to Alaska and Canada. The commercial Niobrara drilling program in which 3,000-foot wells were drilled in as little as 19 hours, from the time the rig moved in until the target depth was reached, followed a Department of Energy-funded (DOE) research project to adapt a conventional coiled tubing rig for drilling exploratory and development wells with ultra-small diameters (1.75 to 4.50 inches). Microhole coiled tubing drilling technology could be applied to bypassed resources in oil and natural gas reservoirs, particularly for shallow reservoirs in mature or depleted fields. According to DOE estimates, more than 218 billion barrels of bypassed crude oil remains in U.S. oilfields at less than 5,000 feet. Recovering 10 percent of this untapped resource equates to an amount equal to 10 years of OPEC oil imports at current rates.
What I’ve dug up so far:
* Unamed operator in those DOE tests is Rosewood Resources – private – Cheyenne county, Kansas, Niobrara formation.
* PETD has many leases in and around this area. Hmm could they be planning microhole ct tests? Growth estimates are huge alreadybut their reserves are relatively small…for now.
* This kind of thing must drive gas bulls nuts. Thankfully for them, the press doesn’t concern itself with reading items off the EIA website too often.
