• ## Bleed & Lubricate

\$2.25

Bleed and Lubricate is a small app that calculates the psi to bleed off for a given amount of mud. An excerpt from a well control manual: Pump mud into the annulus and allow the mud time to fall through the gas, then bleed off pressure at the choke equal to the hydrostatic pressure of the mud...

• ## Hydrostatic Pressure Lost

\$2.25

This little app calculates the hydrostatic pressure lost when so many feet of pipe is pulled without filling the hole. The app has been tested on several different android devices.

• ## Fall to Equalize OverBalance

\$2.12

This little calculation lets one see the distance a weighted fluid column would have to fall before losing the overbalance. An example would be if the BHP exceeded formation pressure by 100 psi using an 11ppg mud what is the distance the fluid would have to fall before losing the overbalance....

• ## Formation Pressure Estimated

\$2.12

Formation Pressure Estimated is a small calculator that takes the SIDPP, Depth and Mud Weight and gives you the calculated formation pressure. This app has been tested on several different android devices.

• ## Pressure Surface for EMW

\$2.12

This calculation gives you the required surface pressure for a given depth and fluid weight. For example - the drilling program called for the formation at the casing shoe to be tested to an equivalent mud weight of 15 ppg with an existing 10 ppg mud. This program has been tested on several...

• ## Surface to Bit Stroke Count

\$2.12

This little app takes the drill string volume and calculates the surface to bit strokes. The app has been tested on several different android devices.

• ## Bit to Surface Stks Bottoms Up

\$2.12

This little app uses annular volume to calculate Bit to Surface Strokes (bottoms up). The app has been tested on several different android devices.

• ## Annulus Volume bbl/ft

\$2.12

This little app calculates the annulus volume between hole and pipe sizes. It also works with the Bit to Surface app for calculation of strokes. The app has been tested on several different android devices.

• ## Cement Mud Differential Calc

\$2.12

This little app calculates the differential pressure of drilling fluid in the casing to cement in the annulus. The app has been tested on several different android devices.

• ## Surface to Surface strokes

\$2.12

This little app calculates the surface to surface strokes. It takes into consideration the drill string volume and the annulus volume. The app has been tested on several different android devices.

• ## Drill String Volume Calc bbls

\$2.12

This little app calculates the drill string volume in barrels. The app has been tested on several different android devices.

• ## Drill Collar wt. per foot

\$2.12

Ever needed to know the wt per foot of a drill collar. This little app calculates that for you based on ID and OD. The app has been tested on several different android devices.

• ## Bollard Pull in metric tons

\$2.12

Calculates the Bollard Pull in metric tons based on the boat's Horse Power. This app has been tested on several different android devices.

• ## Level Drop Pulling Stands

\$2.12

This app gives you the drop of fluid level in feet as you pull stands of drill pipe. The app has been tested on several Android devices.

• ## TVD2 - Find a New MDepth

\$2.12

This little app is the second part to the initial TVD app put up in the Play Store. This takes input to find the new Measured Depth value whereas the initial TVD calculator gives the New TVD. The app has been run on several different android devices.
