The Path to a Fit & Forget

SOLUTION

The FULL SOLUTION requires minimal

data inputs and the In-Situ calibration is

performed:

NO PVT information needed.

The DEAD OIL asset in its pure form

is measured directly, without

assumptions made, without offline

calculations to convert live oil volumes

to dead oil volumes.

MEDENG’s Higher Science

To describe motion of flow caused by pressure gradient:

Local Inertia – caused by unsteady flow

Convective Inertia – the change in acceleration caused by velocity changes,

such as the sudden change in stream lines of flow around an orifice plate.

Oil is non-Newtonian and flow viscosity decreases with

the increase of shear rate

Shear rate is affected by:

well depth (flow history)

flow rate

At certain well depth, a given

shear rate corresponds to a

given viscosity

Viscosity varies with geological conditions of well

Shear Rate

MEDENG’s Simpler Technology

Through fundamental fluid dynamics principles the multiphase unknowns are solved one by one and measured directly in actual conditions:

𝑄𝐿𝑖𝑞𝑢𝑖𝑑𝑠+𝐺𝑎𝑠 = 𝑓1(𝐷𝑃1, 𝐷𝑃2, 𝑃1, 𝑃2, 𝑇, 𝑈𝑙𝑡𝑟𝑎𝑠𝑜𝑢𝑛𝑑)

𝜌𝐿𝑖𝑞𝑢𝑖𝑑𝑠+𝐺𝑎𝑠 = 𝑓2(𝐷𝑃1, 𝐷𝑃2, 𝑃1, 𝑃2, 𝑇, 𝑈𝑙𝑡𝑟𝑎𝑠𝑜𝑢𝑛𝑑)

𝜌𝐿𝑖𝑞𝑢𝑖𝑑𝑠 = 𝑓3(𝐷𝑃1, 𝐷𝑃2, 𝑃1, 𝑃2, 𝑇, 𝑈𝑙𝑡𝑟𝑎𝑠𝑜𝑢𝑛𝑑)

With the pure phase densities in actual conditions 𝜌𝐺𝑎𝑠, 𝜌𝑂𝑖𝑙, 𝜌𝑊𝑎𝑡𝑒𝑟, the

phase ratios can be determined at actual conditions:

𝑊𝑎𝑡𝑒𝑟𝑐𝑢𝑡 =𝜌𝐿𝑖𝑞𝑢𝑖𝑑𝑠 − 𝜌𝑂𝑖𝑙

𝜌𝑊𝑎𝑡𝑒𝑟 − 𝜌𝑂𝑖𝑙

𝐺𝑉𝐹 =𝜌𝐿𝑖𝑞𝑢𝑖𝑑𝑠+𝐺𝑎𝑠 − 𝜌𝐿𝑖𝑞𝑢𝑖𝑑𝑠

𝜌𝐺𝑎𝑠 − 𝜌𝐿𝑖𝑞𝑢𝑖𝑑𝑠

Single phase volumetric flowrates can then be derived at actual conditions:

𝑄𝑂𝑖𝑙 = 𝑄𝐿𝑖𝑞𝑢𝑖𝑑𝑠+𝐺𝑎𝑠 × (1 − 𝐺𝑉𝐹) × (1 − 𝑊𝑎𝑡𝑒𝑟𝑐𝑢𝑡)

𝑄𝑊𝑎𝑡𝑒𝑟 = 𝑄𝐿𝑖𝑞𝑢𝑖𝑑𝑠+𝐺𝑎𝑠 × (1 − 𝐺𝑉𝐹) × 𝑊𝑎𝑡𝑒𝑟𝑐𝑢𝑡

𝑄𝐺𝑎𝑠 = 𝑄𝐿𝑖𝑞𝑢𝑖𝑑𝑠+𝐺𝑎𝑠 × 𝐺𝑉𝐹

The standard gas flowrates can then be converted from its actual conditions using the Equation of State. As a result of this breakthrough method, your valuable asset, the dead oil, is measured directly without the structural inaccuracies associated with the use of PVT.
