How do I get the WinSURV2 daily/BHA reporting program?

WinSERVE and WinSURV2 no longer sold

NOTICE: Due to Windows updates and the antiquity of WinSERVE/2's underlying database structures, data security and program reliability became a major concern. We have decided to devote all of our efforts in refining HawkEye instead. All versions of HawkEye now have integrated BHA/Daily report functionality, and we are committed to improving the HawkEye platform for the years to come.

Upgrades from WinSERVE Discontinued

NOTICE: As of January 1, 2019, PDT is no longer offering a license upgrade from WinSERVE to HawkEye. No version of WinSERVE will be upgradable to any version of HawkEye. In order for existing WinSERVE license owners to obtain a HawkEye license, they will need to purchase a HawkEye license separately and fully, independent of any WinSERVE licenses they own.

Why can't I run the ".NET Framework 4.7.1"?

HawkEye uses .NET Framework 4.5. Most versions of Windows can run this framework.
**BUT** the integrated Dailies/BHA module (which replaced WinSurv2 in June 2019), uses .NET Framework 4.7.1.
The following operating systems CANNOT run this newer .NET framework:

System Requirements and Windows Version

What computer runs HawkEye?

Search for a laptop with 1920x1080 resolution and 8GB+ of RAM and 64-bit Windows.  We recommend websites like and because of their user reviews on the products. Also get a Logitech mouse with Hyperscroll wheel.

Which version of Windows is compatible with which programs?

Compatibility v3

Note: HawkEye is not compatible with Windows XP.

Difference Between WinSERVE and HawkEye


Why pay maintenance?

Maintenance is an optional yearly fee for licensees of the program. It gives the license owner a guarantee of updates, as well as replacement of lost HawkEye™ HASP keys and other technical support.

Without access to updates, a user is missing out on critical new features and innovations that are continuously being added to the software.

The concept stems from the fact that HawkEye, as well as all Performance Drilling Technology programs and all sophisticated software for that matter is a constantly evolving thing.

Programs like HawkEye™ are required to evolve because their native environment, Microsoft Windows, is always evolving as well. Furthermore, the developers of HawkEye™ are working every day to make the program better for its users.

Another thing to consider when it comes to maintenance is how much a program like HawkEye™ is worth to the company at which it's being utilized. If a small directional drilling firm is making on average, say, $1500 per day, HawkEye™ needs to be worth at least a tiny fraction of one percent of that company's yearly income in order to justify the yearly maintenance. From a strict business economics perspective, maintenance is an equitable, prudent and relatively small expense.
