Leak Off Test Data

Interactive Well Site > Available Daily Operations Data

The Leak Off Test form is used to record leak off tests and formation integrity tests. Each Leak Off Test is associated to a specified hole section.  

Leak Off Test data is recorded from the surface and subsurface Daily Operations link.

The Leak Off Test form allows the user to add, review, modify and delete Leak Off Tests data on a daily basis.

For information on how to enter Leak Off Test data, see the Record Leak Off Tests topic.

Special Fields and Functions

Hole Section

The Hole Section field identifies the Hole Section the test was performed on.

BHP

The BHP is calculated as follows:

BHP = (AMW * TVD Test * 0.052) + Surface Pressure


EMW

The EMW is calculated as follows:

EMW =   BHP / (0.052 * TVD Test)

BH Pressure

The BH Pressure is calculated as follows:

BH Pressure = (0.051948051948100 *  AMW * TVD Test) + Pressure

Units Picklist units_pic.gif

The Unit Management System in the EDM™ database controls display units in EDT™ applications. Every numerical element in the EDM database has a storage measure (some known quantity in the physical world) associated with it such as feet, ft/sec, or °F.

In OpenWells® software, Active Viewing Units (or Display Units as they are sometimes referred to) are for presentation purposes only. Display units can changed at any time and do not affect the quality of the data.

Active Viewing Units for the OpenWells application are selected from the Unit picklist located at the top of each page.

Datum Selector datum_pic.gif

The reference point for depths changes over the life cycle of a Well, with changes in rigs and viewing data requirements.

The Datum Selector, located at the top of each page, allows users to change displayed the depth reference point (datum) on the fly.

Changing the depth reference point displays depths relative to the datum selected. This DOES NOT change the values in the database itself.

Data MUST be entered correctly in context to the selected datum reference point.

The following example shows how the viewing datum affects the data you see.
