Are you doing all you can to keep your production from depleting?

Purposeful proppant selection is important in effective stimulation design and especially in maintaining proppant pack integrity over time. It is a technical and economic decision that will affect the production of the well over its producing life and is essential for the economics of a project.  Optimizing proppant design maintains stimulated reservoir volume while maintaining efficient connectivity to the wellbore.

What is the proppant pack?

Proppant grain size, proppant loading, and proppant strength are all factors that affect the integrity of the proppant pack. It is the integrity of the proppant pack that resists fracture closure stress, proppant embedment and proppant degradation.

Are you doing all you can to keep your production from depleting? 

Depletion of the pore pressure over time increases the stress at the fracture face and hence increases the degradation of the proppant pack over time.  Resin coated proppant is the best cost option to combat the growing effective stress due to depletion.  After the resin coated sand is pumped, it forms a grain to grain bond under temperature and pressure.  That grain to grain bond strengthens a proppant pack that resists the stress at the fracture face.  The proppant pack permeability for a given fracture width, created by proppant loading, proppant size, and proppant strength thus leads to enhanced conductivity near the well bore.  Improving the near wellbore propped fracture conductivity is the single most important factor for maintaining reliable and long lasting well productivity.
