Mart Resources Takes Stake in Nigeria’s OML 18 Field

Mart Resources will be leading a consortium to take 45% stake in OML 18.  The remaining 55% will remain with NNPC. The 45% was sold by Shell together with its partners Total and Eni. OML 18 produces between 20, 000 to 30, 000 barrels per day from about 30 wells. OML 18 is onshore.

Remember that Mart Resources is already into agreements with Midwestern and Suntrust to provide technical and financial services, and to participate in the development of Umusadege field.

PRODUCTION LOGGING: OVERVIEW, BENEFITS & APPLICATIONS

As world oil reserves dwindle and energy consumption increases, there is an ever increasing need to optimally drain hydrocarbon reservoirs, such that every drop of recoverable hydrocarbon is extracted. Discovery of new oil fields is becoming rarer and there is a general move by operators to go back to the old wells that are declining in production to see how they can be worked over in order to increase hydrocarbon production.

Reservoir monitoring via pulsed neutron and production logging are two key tools that are used to diagnose the well production problems, discover bypassed hydrocarbon and monitor the production pattern with a view to efficiently drain the reservoir and avoid reservoir damage or water/gas conning. Traditional production logging data is acquired in order to quantify the different phase contributions, identify producing perforations and delineate water entry points amongst other uses.

Production log (PL) data can be used to address the problems highlighted above. In subsequent articles, we would take a look at the different sensors that make up a PL tool string and how the data acquired from these sensors are used to optimize production. We will also look at the slightly more complex array production log tools which are used for deviated to horizontal wells. We would go further to explore how taking a new perspective on PL data can give insights to molecular fluid behavior and help us better characterize the reservoir.

MAIN PRESSURES IN THE RESERVOIR

Overburden pressure is the pressure exerted by the total weight of the overlying formation. It is a function of the height of the rock column and the bulk density of the rock.

Hydrostatic pressure is the pressure exerted by the weight of a static column of fluid that is independent of the dimension and geometry of the fluid column. It is exerted equally in all directions.

Formation pore pressure is the pressure exerted by the pore fluids within the rock/formation.

Fracture pressure is the upper limit at which a rock can withstand pressure from the mud column. It is the minimum lateral stress that must be overcome to fracture the rock.

According to a press release by AFREN (see below), this is connected to some improper/unauthorized payments.

POROSITY

Ø Ratio of the volume of space to the total volume of a rock.

Ø Porosity of a rock is a measure of its ability to hold a fluid.

Ø Porosity is expressed as a percentage of the total rock which is taken up by pore space.

       Total porosity

Ø  the ratio of the entire pore space in a rock to its bulk volume.

       Effective porosity

Ø percent of bulk volume occupied by interconnected pores spaces.

Ø A total porosity less the fraction of the pore space occupied by shale or clay

Ø In very clean sands, total porosity is equal to effective porosity.

    Primary  porosity

Ø porosity of the rock that formed at the time of its deposition.

Ø  primary porosity of a sediment or rock consists of the spaces between the grains.

Ø Primary porosity decrease due compaction and packing of grains.

Ø Intergranular pores of clastics or carbonates.

Ø Primary porosity is less than one percent in crystalline rocks like granite.

 more than 55% in some soils.

      Secondary porosity

Ø develops after deposition of the rock.

Ø Vugular spaces in carbonate rocks created by the chemical process of leaching.

Ø  fracture spaces formed due to stress distortion in reservoirs rocks.

A big congrats to her. I guess President Jonathan will smile to himself and say “this is my beloved daughter, with whom I am well pleased”….

Where does the natural energy of a reservoir come from?

1.  Liberation and expansion of solution gas

2.  Influx of aquifer water

3.  Contraction of reservoir rock skeleton

4.  Expansion of original reservoir fluids

a.  Free gas, if present

b.  Interstitial water

c.  Oil, if present

5.  Gravitational forces
