Reservoir drill-in system have the properties of a good drilling fluid and a completion fluid. Its primary attribute is the development of a filter cake which effectively prevents formation damage and is easily removed, with fil-trate and filter cake being compatible with the completion process. They are usually composed of biopolymers and bridging materials and are designed to match specific reservoir criteria.

Reservoir engineering is a branch of petroleum engineering, typically concerned with maximizing the economic recovery of hydrocarbons from the subsurface. It is defined as the application of scientific principles to drainage issues arising during the development and production of oil and gas reservoirs. It is designed to incorporate high-resolution 3D geologic models into simulation for reservoir performance prediction.

Reservoir Filler Guns are used for refilling automatic lubrication reservoirs. These can dispense 14-ounces in less than 60 seconds and provides up to 1,000 PSI and will not pump air into a centralized lubrication system. These discharge grease cartridge in under one minute at 1 -100 psi. These are compatible with most electric drills.

Reservoir Performance Monitor is an advanced slim hole multi-function pulsed neutron tool. This reservoir performance monitor instrument combines multiple nuclear measurements in one system with industry-leading accuracy and precision.

Reservoir Testing/ Analysis provides operators with the information they need to properly characterize reservoirs and determine the net present value of assets.
