Trabajo Practico 1

A- PERFILES 1- En los perfiles a pozo abierto anexo, indique cuales serían los intervalos a cañonear. ¿Necesitaría más

información?

2- En los siguientes perfiles a pozo entubado indicar en cual podría cañonear considerando la calidad del cemento y por qué. De no poder cañonear indique las razones.

B- Curvas IPR En un reservorio que produce por energía de gas disuelto se han perforado 30 pozos. De un ensayo realizado en uno de ellos se obtuvieron los siguientes datos: - Presión media en el área de drenaje=2500 lb/pg - Caudal de petróleo producido=650 bbld - Presión dinámica de fondo=2000 lb/pg a) Usando la ecuación de Vogel, generar la expresión de la curva IPR

Depth shifts are according to SLB- D&M depth standard

1. Run Objetive: To Drill 12.25" hole section

2. Depth correlated to driller's Depth

3. All data was acquired while drilling, all data is from tools memory.

4. Gamma Ray is envireonmentally corrected for Bit Size, Mud weight and Collar Thickness.

5. No Potassium in the mud.

6. Resistivity is borehole compensated and environmentally corrected for bit size and mud resistivity
