Introduction

A UK southern North Sea Well database for 600+ wells across UK quads 36-39, 41-44, 47-49 and 53-54. For each of the wells, all relevant data is worked up in single-well pressure vs. depth, and mudweight vs. depth cross-plots.

Data includes:

Formation tops
Wireline logs (GR, Lithology, Resistivity, Density, Sonic)
All pressure data (WFTs, DSTs, LOTs, FITS, Kicks, Lost Circulations)
Mudweights
Casing depths
Deviation surveys
Temperature
Check-shots/time-depth pairs
Drilling gas (connection, background and total gas etc.)

Benefits

Analysis of shales – understanding of shale lithofacies and its variation is key to safe well planning and real-time drilling in particular bore hole stability (BHS).
Interpretations of pressure data e.g. free-water levels, gradients and contacts
Interpretations of kicks for mapping purposes – influxes in the Zechstein are the biggest drilling issue in the SNS, and understanding local kick instances and overpressure magnitudes is key to safe drilling of exploration wells and plugging/decommissioning existing boreholes
Well pressure interpretation – detailed pressure analysis of any of the wells include local calibration and interpretation of the hydrostatic pressure, overburden pressure, pore pressure and fracture pressure
Understanding of pore and fracture pressures in drilled wells allows a more confident well plan to be produced in advance of drilling new wells
A full well interpretation also provides a full rock column pressure profile such that porous intervals with potential for flow and non-porous zones can be understood for decommissioning to meet new legislation
Single-consistent and QC’d well database
