46% PROPEL SSP® TAIL-IN VS. SLICKWATER FRAC

ESCONDIDO FORMATION, RICH GAS PLAY

INTRODUCTION

An operator working in the Escondido formation in Webb County, Texas, recorded a 60-day initial production increase of more than 55% using Propel SSP compared with the slickwater offset well. The operator also eliminated fluid sweeps, decreased fluid additives, and reduced pumping time, all of which enhanced production success. These results were achieved in a low-permeability sandstone well with Propel SSP tail-in as 46% of the total proppant volume.

Propel SSP technology was coated on 30/50 Northern White sand compared with uncoated 20/40 Northern White sand used in the offset well. The operator also used 100-mesh and 40/70 Northern White sand in both wells. The smaller-mesh, lower-conductivity frac sand coated with Propel SSP outperformed the larger-mesh, higher-conductivity frac sand, based on the production results, by maximizing the fracture surface area.

THE RESULTS

After 60 days, cumulative gas production increased more than 55%. Gas production for the offset well was 85,207 Mcf compared with 132,678 Mcf for the Propel SSP technology well even with the lower-conductivity sand.

Besides this greater production value with Propel SSP technology, the operator reduced stage pumping time by 25%. The operator used 15% less fluid additives, including friction reducer, biocide, clay stabilizer, and surfactant. With the eliminated fluid sweeps and higher sand concentration, water consumption decreased 10%.
