Wellsite Surveillance Services

Unmatched geopressure and geomechanical expertise at your wellsite

When wellbore conditions start to change, it’s not a good time for guesswork. Tough decisions faced by drillers require solid pore pressure and wellbore stability information.

Our Wellsite Surveillance Services reduce uncertainty with unmatched geopressure expertise at your rig site. As conditions deviate from the pre-drill pore pressure and wellbore stability prediction, onsite Knowledge Systems analysts quickly provide you with actionable, real-time solutions.

We provide the industry’s most dependable predictions of pore pressure and wellbore stability to reduce drilling problems and improve efficiency.

Actionable Information

Key components of the drilling plan-casing points, mud weights and even the trajectory are based on a pre-drill prediction of pore pressure and earth stress. Data acquired while drilling brings new insights into wellbore conditions that can require a change to even the most robust wellbore design.

To remain useful, the pre-drill model must be regularly updated. The revised model results must be quickly and effectively communicated to decision makers, in actionable terms, which are converted into decisions that optimize the safety and efficiency of borehole construction.

Wellsite surveillance ensures that this high-quality communication takes place. Among its advantages are:

• 24/7 analyst availability for critical analysis when and where you need it
• Direct communications with the drilling foreman
• Hands-on analysis of drilling parameters such as cuttings, cavings and gas
• Onsite accountability with a direct link to your office staff and the full Knowledge Systems team

Reducing Uncertainty

Our surveillance services reduce uncertainty in the pre-drill model using LWD and surface logging data acquired via WITS or WITSMLTM transmission protocol. The unique technology not only computes pressure at the LWD sensor, but also updates the seismic and basin modeled predictions for revised information, ahead of the bit, while you are drilling.

Expert analysis onsite also captures valuable information from sources outside the traditional data stream. For instance, our analysts can diagnose wellbore failure
type by examining cavings, and in turn, communicating appropriate remedial action options to the people offshore that need to know.

Analysts also rapidly integrate wireline data, leak-off tests and other subsurface information such that prediction revisions can be quickly and effectively communicated directly to the drilling foreman. The result is a real-time, fully-informed drilling team that can make high-quality decisions about the drilling program.

A Powerful Process

The Knowledge Systems approach to basin modeling data integrates geology, petrophysics, geophysics and engineering for an inclusive analysis that considers all available information.
 
We develop a 3D geologic model of pore, fracture and overburden pressure using all available information. The model is refined by a multidisciplinary team of highly-experienced pore pressure analysts and geoscientists to ensure the results are exceptional, even when time is short and data is limited.

The value of this approach, born out of three joint industry projects and hundreds of consulting projects, is well documented. 

A recent joint industry project (DEA 119 P2) found the technique to be an improvement over well log and seismic-based techniques. The JIP determined that the basin model produced a pore pressure prediction within 1 ppg of the actual encountered pressures over the entire wellbore interval.

A subsequent study (SPE 96464) established that with real-time updating, the basin model could forecast pressures within 0.5 ppg up to 1,000 feet ahead of the bit.
