Acoustic Fluid Level Surveys
Utilizing the Echometer Well Analyzer, Hamdon’s experienced field technician will conduct Acoustic Fluid Level surveys to determine the depth to the fluid in the annulus. By frequently testing fluid levels, the current production of the wells can be evaluated while calculating the bottom hole pressures. Accurate fluid data provided by this test can be used to further evaluate pump performance and determine increased production potential.
Hamdon Energy Solutions conducts Dynamometer Surveys (diagnostic tests) to determine the loads and performance of the artificial lift rod pump system. The survey is designed to interpret the load and displacement at the polished rod of a pumping cycle and identify production potentials and/or mechanical inefficiencies within a pumping unit. The analyzed data is used by operators to optimize the operation of the pumping system, including: increased well pumping efficiency, increased production, longer rod and pump life, less frequent gearbox failures and improved pumping equipment design.
Fluid Depression Test
Also known as the Foam Depression Test. A fluid depression test is conducted to determine the True Fluid Level when free gas is known to be producing up the annulus. To conduct the test, the fluid level is changed by closing the casing valve to the flowline resulting in an increase in casing pressure. This increase in pressure causes the fluid level to be “depressed”. A series of fluid levels with corresponding pressures are used to determine the gradient by measuring the change in the fluid level resulting from the change in the casing pressure.
In typical pumping installations it is desirable to have the pump intake landed below the perforated (or producing) interval, to assist with downhole gas separation and minimize the amount of gas produced through the pump. Determination of the gradient(s) and resulting producing pressure can assist with more accurate determination of the Inflow Performance Relationship (IPR).
Plunger Lift Optimization
The purpose of the plunger lift system is to remove liquids that accumulate in the wellbore to allow the well to produce at the lowest bottom hole pressures. The Echometer TWM system is able to optimize the performance the of the plunger lift system by simultaneously measuring the casing pressure, tubing pressure and acoustic signal during one complete plunger cycle. This software can analyzes the data to determine plunger fall velocity, identify holes in the tubing, stuck plungers, tight spots or restrictions, gas analysis, optimization run times and much more.
Static Bottom Hole Pressure Calculations
Static Bottom-Hole Pressure Surveys determine the bottom hole pressure of a well that has been shut-in or suspended for a prolonged period of time. A fluid level is taken to determine the amount of fluid above the mid-point perforations or datum depth and applying pertinent well information such as recent production history, producing fluid level (if known), fluid and gas gravities, temperatures, the static bottom hole pressure can be calculated.
