CARBOAIR high-transport, ultra low-density ceramic proppant technology increases production and EUR from slickwater fracs

New Mexico

The challenge
The effective stimulation of a “wildcat” well with a thin gross pay (100 ft. section gross interval) in the 2nd Bone Springs formation. The operator drilled this well based upon vertical open hole log data from a nearby well. There were no wells within six square miles when this well was drilled. Typical high pump rate slickwater fracs with 100 mesh and 40/70 mesh sand are common in the area. The design goal was to achieve a greater propped frac half-length in the formation to optimize the thin gross pay, with the intent to flatten production decline in this marginal area.

The solution
CARBOAIR, an ultra low-density (2.0 specific gravity) ceramic proppant, was pumped as a tail-in to promote greater propped frac half-length. CARBOAIR technology has exceptional transport characteristics and significantly more volume per pound. Pre-frac analysis using a 3-D Fracture Earth Model showed significant increases in propped length and height when comparing a lower density proppant like CARBOAIR to conventional sand. Twenty-six frac stages were pumped, using a much smaller amount (by weight) of CARBOAIR to achieve the equivalent volume as 40/70 conventional sand (ASG 2.65).

The results
Average daily oil production has remained stable; the post-fracture decline rate was shallower than other wells in the area, attributed to the increased contact area due to the improved effectiveness and transportability of the CARBOAIR, as well as higher fracture conductivity. The well was put on artificial lift approximately 9 months into production. Over the nine month period, oil production averaged more than 300 BOPD with cumulative production of 130,000 BOE to date. This work has been documented in SPE-187498.
