Positive Pulse MWD

Geowell’s positive pulse MWD system was developed with two particular goals in mind: Reliability and Sustainability. Our MWD systems are resistant to high concentrations of lost circulation materials in the harshest drilling environments. Our client base will receive a robust, downlink-capable system that is simply superior to most MWD systems available.

The robust NVADER pulser is perfect for any lost circulation issues. Geowell’s rotary connections decrease tool length resulting in closer gamma and directional sensors to the bit.

Conventional MWD systems suffer from performance, reliability and maintainability issues and are prone to failure in high-percentage LCM, high wash, and harsh environments. Geowells aims to offer the most power-efficient and reliable positive pulse motors in the market to our clients. This improves durability, efficiency, flexibility, performance, and sustainability.

Smart Collars

Our smart collar tool was designed to eliminate the expense of an on-site MWD operator and/or directional driller. It is easy to operate from the rig floor through the Pason Directional program while acquiring only inclination and azimuth.

If tool faces or gamma is required, an additional high-resolution monitor is installed in the cockpit that allows for remote support in steering the wellbore and/or remotely logging gamma. We set up the VMS/RVMS system in our shop and then it is delivered to your site and left with rig personnel. The personnel simply put it in the bottom hole assembly and start drilling.

Mud Motors

We have some of the most robust power sections and motors in the market. Proven in challenging and hot-hole drilling conditions, our motors consistently give out some good output. Our motors provide some of the highest flow and torque values in the market thus increasing the rate of penetration significantly.

Our motors are made of high-quality steel and minimal components making for robust equipment which offers great performance even in extreme temperature and pressure environments. We offer 3 3/4″ to 9 5/8″ motors in every available power/torque ratio.

Motors are available in fixed and adjustable bends and feature a 50″ bit to bend with a 34″ spacing available upon request. We also avail specific power sections for job-specific purposes thus ensuring fast drilling times on every job we take.

Borrox AP Reamer: Get enhanced and fully customizable hole-gauge-maintenance and torque-reduction characteristics for a variety of formations and applications.

Measuring While Drilling (MWD)

We deliver accurate directional azimuth, inclination, and tool face data in all drilling environments from routine to extreme. Our measurement-while-drilling (MWD) systems leverage several telemetry methods to reliably transmit data to the surface, even in wells subject to heavy vibration, high-lost-circulation-material content, high flow rates, and high doglegs.

In MWD, there are three main sets of data that we look for and transmit.

– Directional Information which mainly comprises measures of inclination and azimuth at a location. Measurements of inclination, azimuth, and tool face are also measured at specific intervals to ensure the well does not venture outside restricted drilling space.
– Drilling Mechanics Information which comprises information about the drill bit. This information includes the rotational speed of the drill string, smoothness of that rotation, type and severity of any vibration downhole, downhole temperature, torque and weight on bit, measured near the drill bit and mudflow volume. This information is important in operating the tool more effectively thus avoiding tool failure
– Formation Properties are measured to make it possible to perform geosteering, or directional drilling based on measured formation properties, rather than simply drilling into a preset target.

Logging While Drilling (LWD)

Our logging-while-drilling (LWD) systems deliver high-quality reservoir description data. Our LWD technology transmits real-time petrophysical, geosteering, imaging, geophysical, and geomechanical data that enhances reservoir understanding and enables real-time adjustments regardless of the environmental conditions one is working within.

This is crucial to ensuring the integrity of the well. The following loggings are made:

– Natural gamma ray
– Sonic loggings
– Resistivity loggings
– Neutron porosity loggings
– Density and photoelectric index
– Borehole calliper
– Borehole images
– Formation tester and sampler
– Nuclear Magnetic Resonance (NMR)
– Seismic while drilling
– Pressure testing

Shock Tools

Our shock tools are designed to provide an improved rate of penetration and to minimize axial vibrations produced by the drill bit during drilling operations. The tool will absorb the shock load on the drill string and drill bit. The robust nature of our shock subs means that they can drill in any type of rock formation whether soft, medium or hard. The Shock tools also reduce vibrations utilizing a series of springs and they can be equipped with light, medium or heavy-weight springs to accommodate various drilling conditions.

Our shock tools are designed to absorb shock and vibration and vertical bit displacement in drilling applications. This gives the driller ability to calibrate weight on bit and rotary speed, resulting in a faster penetration rate. Absorption of shock helps in maintaining and lengthening the lifespan of the drilling equipment as well as maintaining the integrity of the bottom hole assembly in general.


Whip Stocks

Geowells International Ltd offers high-quality, international standard whipstocks which are used to cut a window into existing wellbores. We provide whipstocks that can be used in a variety of wellbore configurations. They can be used in a vertical high-angle hole for sidetracking the original well or in preparation for directional or horizontal drilling.

Not only can our high-quality whipstocks be used to exit casing for horizontal entry into alternative productive well zones, but also to sidetrack wellbore damage, junk in the hole, or other negative well conditions. They can also be used to re-enter zones with economic reserves still in place.

We supply the following whip stock equipment:
