PTA is a Reservoir Engineering tool when we infer drive mechanics. Gas caps reveal themselves in the pressure buildup because of a dramatic change in reservoir fluid viscosity (µ) — the gas/water interface manifests as a deviation in derivative
So are we… Re-branding with a fresh new website to publicize our Technical Coaching employee training and development material. Well testing is about measuring and recording flow rate and pressure data. Talented and experienced wellsite equipment operators are always
PTA is a Reservoir Engineering tool when we qualify induced fracture (frac’) effectiveness. Successful fracture stimulation treatments generate an Infinite Conductivity pattern, identified by a long Linear half (½) slope dominating the pressure build-up. Less effective treatments generate a
PTA is a Reservoir Engineering tool when we differentiate dual porosity or, more particularly, natural fracture vs. matrix deliverability. Natural fractures derive from tectonic events: folding and faulting. Permeability in natural fractures is orders-of-magnitude higher than in porous rock
So are we… Re-branding with a fresh new website to publicize our Technical Coaching employee training and development material. Corporate directors, managers, and stakeholders depend on realistic, practical, advice from testing wells. Petroleum Reservoir and Production Engineering teams initiate
PTA is a Reservoir Engineering tool when we derive insitu permeability to oil, gas, or water. Remember, PTA analytical equations solve not for permeability (k), but transmissivity (kh/µ); net pay (h) and viscosity (µ) are assumed to be constant
PTA is a Reservoir Engineering tool when we identify reservoir flow regimes. Flow regime development, or lack thereof (obscured, absent, transient), is crucial to analytical confidence levels. Vertical Radial flow was the norm fifty years ago: easy discovery, conventional,
So are we… Re-branding with a fresh new website to publicize our Technical Coaching employee training and development material. Technical Coaching is for anybody new to a welltest workspace: wellsite data acquisition, field-office data processing, or engineering data analysis.
Welltesting & Pressure Transient Analysis (PTA) are Vital Tools for Upstream Oil & Gas Strategy. Welltesting and PTA are disciplines of Reservoir and Production Engineering. Reservoir engineering because: we identify insitu flow regimes, interpret matrix and fracture flow characteristics,
