... and they are, therefore, routinely ignored by operators. This paper presents a simple way to predict condensate production from the gas production by means of readily available early years’ production data. This simple methodology includes a new specialized plot to find related parameters for condensate production...

... are uniquely high among shale gas reservoirs, and require special treatment. We show that the methods developed by Patzek, et al., PNAS, 110, 19731-19736, can scale all individual wells' gas productions to fit upon a single, universal curve. Haynesville wells can take months or years for flowing tubing...

... We propose the following analysis procedure: Obtain water and gas flowback data (production rates/pressures and cumulative production data) corresponding to early gas production. Plot GWR vs. time to indentify flowback regions; Early Gas Production (EGP) and Late Gas Production Evaluate...

... Abstract Shale gas production has been gaining worldwide attention over the past several years. This is due to the economic gas reserves using two current advanced technologies that are horizontal drilling and multistage hydraulic fracturing. Shale has a high total organic content (TOC...

... Determining the petrophysical characteristics of a reservoir (e.g. permeability) and predicting production of gas-bearing shales is essential for economical assessments prior to field development. However, there is no standard model available to predict gas production from shale strata. Existing...
