New to petroleum Welltesting? Production Testing services clean up and flow test wells. Production testing teams operate a range of equipment from simple one-man flow provers to complicated four-stage separation and multi-phase metering manned 24/7 by tandem crews.
PTA is an Evaluation tool when we forecast hypothetical cases to probe and ascertain project viability. Theoretical, what-if, scenarios can be generated to evaluate economics and feasibility of proposed projects. For example, completing a PTA once, management wondered what-if
PTA is a Marketing tool when we generate theoretical test designs for financial sales presentations. Externally for attracting capital investment, or internally for budget proposals. Hypothetical, what-if, scenarios can easily be generated, complete with productivity forecasts into the future.
New to the term Wireline? Wireline services run welltest pressure instruments. Slickline operators, equipment, tools, and instruments are intrinsic to petroleum welltesting. Welltest 101: Wireline focuses on topics related to wireline (slickline) deployment of subsurface pressure
PTA is a Geological tool when we test CBM desorption properties. Coalbed Methane (CBM) is a Biogenic gas, very high C1 content, clean burning, plentiful here in Alberta, Canada, perfect for heating homes, stores, barns, workshops, and greenhouses from
PTA is a Reserves tool when we analyze gas material balance. Of course, MBA requires at least two satisfactory test results and quality production accounting. Maybe two tests are okay for a single well, but in a pool with
Did you know that Mini-Frac’ or Diagnostic Fracture Injection Tests (DFIT) can “Double For Initial Tests” in Alberta if subsurface pressure recorders are installed long enough. Formation leak-off data can be extrapolated to a p* acceptable for AER Initial
PTA is a Reserves tool when we model reservoir boundaries. Analysts often assume a single drilling spacing unit (DSU) for external boundaries and, thus, volumetric reserves. This is an acceptable standard for initial tests, which are usually (hopefully) infinite
PTA is a Geological tool when we ascertain rock mechanics. Diagnostic Fracture Injection Tests (DFIT), Mini-Frac’ tests, and Step-Rate tests all evaluate hydraulic rock-stress properties. G-Function analysis quantifies break-over pressure, frac’ closure pressure, closure dynamics, and frac’ gradient. Known
Did you know that Alberta gas wells with deliverability over 300 e3m3/d require multi-rate or isochronal flow tests? Moreover, but little known, is that: if you didn’t do a multi-rate test, but did do a pressure build-up test, and
