Control stations, pumps, telemetry and inline measurement — selection to the well regime and supply to order.
HTD has legal entities in all five countries where it has offices, with the head office in Kazakhstan. Equipment has been supplied to Kazakhstan, Uzbekistan, Kyrgyzstan, Azerbaijan, the United Kingdom, Egypt, Iraq, Saudi Arabia, the UAE and Oman, and the rotary steerable service base is in Aktobe.

Artificial lift, pumping systems, downhole equipment protection, surface control, telemetry, simultaneous separate production, modular process packages and inline water-cut measurement.
Sucker-rod-less plunger system with a linear motor
A high-efficiency pump for low-rate well stock. It works where a rod string runs into wellbore curvature — with no risk of rod breaks or tubing wear.
* Marked figures come from internal technical materials and are refined in the assessment for each asset.
LinearLift
A linear motor moves the plunger directly: the copper-wound stator stays still while a magnet slider travels inside it. No rod string, no pumpjack, no rotating parts. Shown without the housing.

ScaleResist
A resonance-wave system that reduces scale on ESP downhole equipment without continuous inhibitor dosing.
Not datasheet ranges — what the equipment has already run in the field.

* Internal HTD field statistics, not independently verified. The outcome for a specific asset is established in the assessment and does not transfer automatically to another well stock.

VIKS
Continuous water-cut measurement directly in the pipeline — without preliminary free-gas separation.
Equipment we have supplied operates for international oilfield service and national oil companies.

Company names are listed as supply recipients. Logos remain the property of their owners and imply no partnership, endorsement or approval.

Control stations
Surface control stations for the downhole motor: bringing the well onto regime, controlling flow and protecting the unit from abnormal operating modes.

HTD supplies D-Tech rotary steerable systems into the ownership of an operator or a service company and takes on everything else: repair and maintenance at the Aktobe base, spare part supply, training for your directional drillers and MWD engineers, and drilling support. The range covers hole sizes from 5 7/8" to 18 1/8", working temperature up to 150 °C and pressure up to 137.9 MPa.
Authorised distributor of D-Tech rotary steerable systems in the Caspian region since 2022
The usual first step is drilling a section with our tool and our engineers. A quote needs only the well profile, the mud type and density, and the flow rate range.
What the direction covers
D-Tech RST rotary steerable systems and MWD telemetry, with spares supplied to the scope of your drilling programme. The tool stays with you: your schedule no longer waits on a service contractor queue.
A service base in Aktobe. After every run: full teardown and inspection with photographic records of each part, memory download, and a written report analysing the drilling parameters.
Preparing the operator’s directional drillers and MWD engineers to run their own tool. A service centre on your own site and partial local assembly are worked out separately.
Remote monitoring of active rigs, parameter review, BHA and hydraulics optimisation. Downlink by flow rate through the mud logging unit, real-time exchange with MWD: inclination, azimuth, collar rotation, shock levels.
One platform covers the whole diameter range, from a sidetrack to a conductor section.

D-Tech figures
In development since 2005, in serial supply since 2015; manufacturing and R&D in Bristol, United Kingdom.
Technical parameters follow the D-Tech specification. The package, the crew and the scope of work are set by the profile of the specific well and fixed in the drilling programme. Data on wells drilled is published once the operator has agreed to it.
The core of the business is supplying oilfield production equipment: selection against the client specification, project packaging, sourcing against the specific order, delivery to site, supervision and commissioning within an agreed scope. Both oil-producing and oilfield service companies work this way with us — wherever supply, start-up and service are easier to close in one contour than to assemble piece by piece.

What the supply covers
The scope is assembled from the specification and the well regime, not from a catalogue line.
Sourced against the specific order and shipped to site on agreed dates, with passports and documentation.
Supervision and commissioning on site — a separate line of the project, within an agreed scope.
Support during operation and analysis of abnormal events on the well stock. Warranty obligations come with the supply; well-stock analytics is a separate service.
A Kazakhstan legal entity. Supply scope, schedule and site work are fixed in the specification for each project.
Call, write, or leave a request in three steps — an engineer will follow up to confirm the field inputs.
HTD AI
Launching
HTD AI is a direction now being launched: artificial intelligence as a tool inside products for oil production rather than a separate service. Specific functions, dates and effects will be stated once there is a working product behind the words.
