“…However, these additives add little benefit when used in completion fluids in most UGTO shale plays when permeability is low and swellable clay content is <30%. Temporary clay protection can be accomplished in certain UGTO completions by simply using a brine or treated produced water, where the TDS is >10 000 mg/L and either Ca 2+ or K + ions are present. , Furthermore, cationic polyacrylamides (i.e., C-PAM) can play a dual role by imparting clay stability while also acting as FRs during HF activities. , A technical discussion between production chemist/engineer, reservoir engineering, and petrophysics experts is important in deciding the best strategy for specific assets based on safety implications and economic goals.…”

Improving production of shale gas and tight oil from low-permeability formations has dominated the energy landscape over the past two decades. Successful applications of horizontal drilling combined with hydraulic fracturing (HF) techniques, first demonstrated in the Texas Barnett shales in the 1990s, are the impetus for the current shale boom in the Americas. Chemicals are at the heart of the fracturing (or "fracking") process, which includes pumping a water-based fluid and proppant into a shale formation to create fissures that access the buried hydrocarbons. The fracturing fluid composition is critical to the completion design and should reduce wellbore friction while enabling proppant placement into the fractures. However, adding too many chemicals without properly evaluating the fracturing fluid formulation can lead to increased cost, poor fluid performance, or even damage to the reservoir. This review discusses the purpose of each chemical used in HF fluids, the techniques applied by the production chemist to assess fluid performance, and suggested best practices in optimizing formulations to reduce costs, enhance performance, and improve footprint.

Thermally-activated, single-component resin formulations in which the catalyst is included in the resin composition can be challenging to place over intervals longer than 30 feet (9.1 meters). Despite the proven consolidation performance observed with epoxy-based systems, initial viscosity and rapid reactivity leading to short placement times have resulted in the industry seeking alternative chemistries to enhance formation integrity. Herein we report the development of a 2-stage formation consolidation system entailing a hetero-aromatic-based resin composition that, once placed downhole, will only begin curing with subsequent introduction of an activation fluid. The latent property of the updated resin formulation allows for extended lateral applications, and incorporating a new surface modifying agent allows for the treatment of formations with an excess of 20% wt—clay mineralogy.
