One of the main challenges for a drilling operation is to comply with Mexico's Zero Discharge policy where the process of logistics and drill cuttings waste handling/transportation is a key part for the pre-drill planning to ensure that ongoing drilling operations are maximized. Any delays in chain of events can result in bottlenecking the drilling performance, thus increasing drilling cost and time for the project. This part of the project requires a dedicated integrated strategy to deliver the drill cuttings from the rig, to the workboat, and transported back to the shore base facility even in rough weather conditions.BHP BILLITON collaborating with Schlumberger deployed an alternative waste management process that replaced the “skip and ship” or conventional cutting boxes method. The conventional method uses numerous cutting boxes and many crane lifts to move waste from the rig to the workboat, but presents a higher HSE risk and potential bottlenecks to drilling performance. The new solution, CleanCut technology pneumatically transports cuttings from the shale shakers to specially designed storage unit (ISO-Pumps) located on the rig that also serve as buffer storage in the event of bad weather. The cuttings can then be pumped from the ISO units on the rig to waiting ISO units on the boat or other storage containers on the supply vessel. The transportation of the cuttings from the shale shakers on the rig to the shore base is achieved with minimal or zero crane lifts thus minimizing harm to personnel.The CleanCut system achieves a safer work condition and ensures that drilling operations can continue unimpaired to achieve the drilling performance. The successful application on the BHP BILLITON Trion 2-DEL well enabled the project to reach Rate-of-penetration (ROP) approximately 58% higher than the average Deepwater well drilled in similar zero discharge condition (*referencing Schlumberger Database). A total of 1108 tons of cuttings were transported safely during the first well operation.","PeriodicalId":335882,"journal":{"name":"Second EAGE Workshop on Deepwater Exploration in Mexico: Knowledge transfer and collaboration from shelf to deepwater","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134165957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the recent popularity and emergence of machine learning in the oil and gas industry there has been a renewed appreciation of the importance of global and regional datasets. This is in part due to the fact that when implementing various machine learning codes, it is apparent that the availability of training data and the quality control (sense-checking) of the outcomes play an important role on the validity of the algorithms ( Naeini and Prindle, 2018 ). In this paper we introduce one concept of a regional study that focuses entirely on subsurface pressure assessment and we seek to highlight how these types of studies can be of high value importance throughout the entire exploration, development and production cycle ( Edwards and O'Connor, 2015 ). We focus particularly on the value of regional datasets viewed as analogous information to help de-risk new acreage for example, in the largely un-explored deep-water, Offshore Mexico acreages.","PeriodicalId":335882,"journal":{"name":"Second EAGE Workshop on Deepwater Exploration in Mexico: Knowledge transfer and collaboration from shelf to deepwater","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115170015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Winter","doi":"10.3997/2214-4609.201900336","DOIUrl":"https://doi.org/10.3997/2214-4609.201900336","url":null,"abstract":"Summary Historical paleogeographic maps and sedimentary models of the Upper Miocene to Pliocene Sureste shelf margin describe middle to outer shelf, wave-dominated deltaic systems, inboard of their coeval shelf-edges and updip of significant deepwater slope reservoirs. The mechanism of sedimentary delivery from the shelf to the slope is shown to be shelf-incising submarine canyons, which tap into perched shelf deltas that do not prograde to the margin/upper slope. While a geological model of sediment delivery from the shelf to deepwater via shelf-indenting submarine canyons is sound, the absence of such canyons in the offshore seismic datasets, presence of laterally persistent train of growth-faults and linked counter-regional faults and anomalously thick deltaic deposits in offshore wells suggest that the Sureste deltas did indeed frequently make it to the shelf-edge and the paralic reservoirs in the Southeastern Basin are in fact shelf-edge delta systems, similar to sedimentary systems in the US Gulf Coast offshore Louisiana and the Orinoco prism offshore Trinidad. Amplitude extractions just below the present-day seafloor (a proxy for the last sea-level lowstand) on the Sureste margin show shore-parallel amplitudes inboard of the modern shelf edge and a distinct change to regional, shore-normal channel geometries beyond the margin. This supports the geologic model of shelf-edge delta systems nourishing a regional upper slope with turbiditic sands. This alternative model has two main consequences: 1) significantly thickened paralic reservoirs in the Sureste shallow water, and 2) a more ubiquitous sediment delivery mechanism to the regional slope, where underlying salt withdrawal provides a structured slope onto which turbidite deposits can be ponded. A key feature of shelf-margin deltas that is important in predicting deepwater reservoir distribution is a highly-unstable delta front to upper slope region. An interesting observation on the present-day seafloor amplitude maps in Sureste is that the observed slope channel systems do not occur directly beyond the shelf edge, but rather 5–10km further downdip. Seismic profiles in the relatively unstructured Veracruz Basin to the west show a prograding shelf-margin system with clinothems. Directly downdip of the shelf edges are highly chaotic seismic packages, interpreted as mass transport deposits (MTD's) associated with instability on the margin. These deposits are thickest on the uppermost slope and thin downdip, over a distance of 10's of km. Eventually they transition to more conformable seismic reflections, suggesting the MTD's erode much of the uppermost slope stratigraphy. This quiet zone just outboard of the shelf-edge that transitions downdip to channelized geometries in map view is also observed on the Orinoco shelf-margin. Seismic sections and piston coring of this profile confirm an upper slope, MTD-dominated setting that transitions downslope to a sandstone-prone channelized setting.

This study characterized the deposits of Fan 3 and 4 to understand the facies architecture of one of the less understood depositional environments: the deep-water deposits. Hammerkranz 1 to 3, Ongeluks River and Klip Fontein Farm outcrops, distributed across the Tanqua depocenter, were studied to gather geometric data, such as thicknesses, NGR, and facies proportions. These data will help to predict the architecture and position of each lobe within a lobe structure. Seven facies models were built to represent the geology and main heterogeneities into a reservoir perspective. A surface-based modelling, and a Sequential Indicator Simulator (SIS) method were adopted in the case of lobe architecture. In the case of channel architecture, object-based modelling and SIS method were applied. The purpose of having different modelling methods is to see which of them best honour the geology. Results showed a better representation applying surface based and object-based modelling in lobe and channel architecture, respectively. However, SIS method displayed a better distribution of small heterogeneities in both cases.

This kind of geometry is specially demanded at the early stages of field development, when velocity models may still be under refinement.

One of the questions from the ZVSP deployment is how this technology can provide decision support before the drilling is complete. Here we present a field case offshore Mexico, in the Tabasco coast shallow waters, where a ZVSP was successfully used as a geo-stopping technology in a “look-ahead” fashion, enabling the identification of an unexpected salt body ahead of the bit and a potential missing geologic formation in the sequence, which in turn allowed on-time well repositioning.","PeriodicalId":335882,"journal":{"name":"Second EAGE Workshop on Deepwater Exploration in Mexico: Knowledge transfer and collaboration from shelf to deepwater","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133957100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
